alternanthera caracasana life cycle
Clade B2 (Node 4; Figs 1â3): A. philoxeroides and A. obovata, both formerly placed in section Bucholzia (Moquin-Tandon, 1849; Schinz, 1934; Fig. The model showed that tuber weight reached a maximum yield of 96 ton/ha in noninfested soil. 1]. Foliage: Greyish green, Heart shaped leaves, red stems, hairy fruits, 2.5 inch orange small flowers Our results depict all C4 species in Clade B3 (Figs 1, 3) with several of the species widely distributed in tropical and subtropical America, whereas A. microphylla is an endemic of dry chaparral vegetation at high elevations in the central Andes (Borsch, OrtuÃ±o & Nee, in press). When aliquots of either tomato or potato root leachate were mixed with different soil samples, hatching factors exhibiting G. pallida-selective hatching activity showed less affinity for the soil matrix than did those selective for G. rostochiensis . Plant parasitic nematodes cause significant crop damage globally. However, species with pedunculate inflorescences or both sessile and pedunculate inflorescences also occur in this clade [subclade B1 and A. philoxeroides (Mart.) For most species a linear regression accounted for >90% of the variation in germination rates for temperatures up to the thermal optimum. Type of trichomes was characterized by SÃ¡nchez-del Pino & Flores Olvera (2006). Kentucky bluegrass required a longer thermal time to germinate than the other species and exhibited conditional dormancy at 25Â°C, which affected the use of the thermal time model. This can be achieved by breaking with industrial agriculture and using an agroecological approach, whose main pillar is the 11. Potato cyst nematodes hatch in response to hatching factors (HF) present in potato root leachate (PRL). Soil amendment with high rates of urea provided some reduction in populations but was not an economically viable option for managing potato cyst nematodes. The coefficients of potato yield achieved under each initial nematode density were integrated into the SUBSTOR-DSSAT potato growth simulation model. A manifold of these units was assembled to increase operator efficiency. Though resistant cultivars to common species (M. arenaria, M. incognita, and M. javanica) are available, they are not effective against other major species of root-knot nematodes. A significant association was demonstrated between late blight infection in the foliage and tuber blight incidence under field conditions. The single MPT resulting from the plastid DNA data shows character state transformations of 11 morphological characters listed in Â Appendix 2. between 20 and 40 mm diameter). The presence of differential interaction, independent of R-gene-based resistance, indicates some adaptation of P. infestans to partial resistance and consequently adverse effects on the stability and durability of partial resistance to potato late blight. The carbon isotope ratios of the three previously identified C3âC4 intermediate taxa were in the same range as the C3 species. The fractionation of root leachates from tomato and potato on a Sephadex G-10 column revealed many similarities between the elution profiles of hatching activities towards potato cyst nematodes (PCN). The root mean square error of the model prediction was about 2 days. The PNW spans three ecoregions as defined by Omernik (1987) and outlined by the Commission for Environmental Cooperation (1997). The ILD test was conducted to evaluate if there was significant conflict in signal between plastid DNA and ITS, and between plastid DNA and morphology data. Alternanthera caracasana Kunth. Apart from considerable morphological variation among populations of many species and high phenotypic plasticity that has led to the description of many infraspecific taxa such as forms, varieties and subspecies in Alternanthera (e.g. Hence, the current review, we summarize on how hypersensitivity-like reactions can enhance plant resistance inducers in solanaceous species and their effects of various root metabolisms, chemical compounds which can act as repellents, hatching stimulants, attractant, or as inhibitors. Most of the species included in this clade [subclades B2âB4 (57% JK, 0.94 PP); Fig. Nevertheless, based on the results of this study it appears that the evolution of photosynthesis in Alternanthera does not exhibit a stepwise development from C3âC4 intermediates to C4. Outgroup taxa included Pedersenia cardenasii (Standl.) Selection for combined low thermal and photoperiod sensitivity, however, would be impractical on an experimental basis, and would therefore require genetic markers. PCN populations were treated with PRD collected weekly throughout the trials, mimicking the natural release of chemical stimulants from growing potato roots. 0 = sessile, 1 = pedunculate. The ability of the late blight pathogen Phytophthora infestans to form oospores in leaves of seven potato cultivars was examined at different incubation temperatures under controlled environmental conditions and under field conditions. These results suggest that soil micro-organisms play an important role in the production of hatching chemicals and it is proposed that the differences in HF profiles between sterile and non-sterile PRL were due, at least in part, to increased HS production in the non-sterile PRL. Amplification and cycle sequencing reactions were run on a Gene Amp PCR system 9600 (Applied Biosystems). 1) and both have pedicellate flowers, a homoplasious character [character 4(1); Â Appendix 2]. suppression were greatly reduced when using the B. juncea seed meal extract. The cultivars tested were resistant to both species of PCN. Some species of amaranths are also major noxious weeds (e.g A. palmeri). Forb Plant Description Origin: Introduced Life Cycle: Perennial Similar Species: Alternanthera sp. Various parts of the wild tomato have been widely used in prevention and treatment of numerous diseases including hypertension, diarrhoea, and respiratory and urinary tracts infections. Resistance of eggplant (Solanum melongena L.), its wild relatives and six intervarietal/interspecific hybrids of Solanum was evaluated with respect to five specialized plant pathogenic strains of Pseudomonas solanacearum. This yield reduction in total production was 6.9%, 20.5%, and 56.8%, respectively. PCR conditions for amplifications of the rpl16 intron were: one cycle at 94 Â°C for 3 min; 30 cycles each at 93 Â°C for 1 min, 55 Â°C for 1 min and 72 Â°C for 1.5 min; and one cycle at 72 Â°C for 5 min, hold at 4 Â°C. Although this attribute resolved as homoplasious, features of the gynoecium should be studied carefully with scanning electron microscopy to examine their potential importance in the taxonomy and classification of Alternanthera (see also Â Appendix 2; Fig. Rates of B. juncea seed meal greater than 2.2 t/ha and 4.5 t/ha for G. pallida and G. ellingtonae, respectively, were required for egg hatch suppression, as determined by a potato root diffusate (PRD) bioassay. Six potato (Solanum tuberosum) cultivars (Home Guard, Bintje, British Queen, Mans Piper, Pentland Dell and Saturna) were inoculated with Vaminoc (a commercial mixture of three selected arbuscular mycorrhizal fungal (AMF) isolates) and with two of the individual AMF isolates present in Vaminoc, Glomus intraradices (BioRize BB-E) and Glomus mosseae (isolate BEG 12). Three consecutive processes, i.e., germination, subcrown internode elongation, and coleoptile elongation, are involved during the period from seeding to seedling emergence. To improve amplification, bovine serum albumin (0.25 Âµg ÂµLâ1), dimthyl sulphoxide (10%) or betaine (1 m) were added. The material and content contained in the Greenbook label database is for general use information only. Purified products were cycle sequenced with dye terminator ABI Prism Ready reaction mix v.3.1 (Applied Biosystems). and A. serpyllifolia Urb. occurs along the east coasts of tropical America and three varieties in the west coast of tropical Africa (Pedersen, 1990). The eastern part of the PNW, encompassing the middle portions of Washington and Oregon and southern portion Idaho is part of the North American Desert region. The implications of these findings for the adaptation The ability to reduce the amount of material being applied to soil by using an extract has the potential for integration into a G. pallida eradication program. 9,95Mb (rv. Alternanthera filifolia is a highly variable species with numerous infraspecific taxa (Howell, 1933; Eliasson, 1971). The quantification of different periods of growth and root length of S. sisymbriifolium against the hatching of 1-and 2-year-old Globodera pallida cysts was done using potato crops with nematode inoculation densities of 288 and 578 nematodes g -1 soil. Hatching of potato cyst nematodes is induced by root exudates of Solanaceae, such as Solanum sisymbriifolium, and is therefore related to root length distribution of this crop. The rate of G. rostochiensis reproduction on both resistant and susceptible cultivars was negatively correlated with Pi. Study the parts of the plant. With the lack of a proper taxonomic treatment, especially for subclade B4 (A. tenella and relatives), the evolutionary position of plant individuals should be determined by generating sequence data from markers otherwise used in phylogenetic analyses, ideally by studying wild material from documented origins and by keeping voucher specimens that can later be analysed for features of the phenotype. Comparisons between tree topologies show a conflict with regard to the position of four species in the plastid and nuclear trees (Figs 1, 3). Seed germination rate increased with temperature up to 36 C, then declined at 40 C. Rate of rhizome bud break increased with temperature up to 32 C, then rapidly decreased with further temperature increases. GalÃ¡pagos Alternanthera spp. Sequences were electrophoresed on an ABI 377XL DNA automated sequencer. Amaranth is an ancient crop in which interest is being renewed, due to its adaptability, stress tolerance, and nutritional value. Alternanthera serpyllifolia, A. olivacea and A. geniculata occur in the Caribbean islands (Standley, 1917), and only A. olivacea has been collected outside the islands in Brazil, Venezuela, Costa Rica, Nicaragua and Panama (Burger, 1983). About one-third of the ITS sequences showed polymorphic sites that hint to introgression or hybridization (divergent paralogues; Table 4). When N was broadcast, soil mineral N measurements showed that, initially, N was preferably taken up from soil compartments near the maize row resulting in lateral gradients, that sometimes even persisted until final harvest. Four temperature response models were compared describing the emergence rate of Solanum sisymbriifolium (L.) over a broad range of suboptimal temperatures and at different soil water potentials. Edited sequences were automatically pre-aligned with Clustal X v. 2.0.12 (Larkin et al., 2007) using default settings. Model predictions of the time required for seedling emergence agreed reasonably well with the observed times, although the model preformed better at higher than at lower temperatures. Oxford University Press is a department of the University of Oxford. to 55.2Â°C for soyabean; reliable estimates could not be made for cowpea, but the results suggest higher and more variable Specific epithets of the flowering plants of central French Guiana EDMUND E HECKLAU, SCOTT A . Solanum torvum was found more resistant than S. sisymbriifolium, because grafted infected plants developed mild symptoms, as indicated by significantly lower leaf symptom index (average value 1.2 and 2.22) and disease index (average value 1.55 and 3.38), respectively. 0 = laciniate, 1 = crenate. Three levels of soil compaction were made by different combinations of artificial compaction and rotary cultivation. Midrib of bracteoles in some taxa is sharply keeled and became strongly curved, having a boat-shaped form. Thus, far the best sampling included only 13 Alternanthera spp. Trichomes on tepals are present in most of the taxa and absent in Pedersenia hassleriana, Alternanthera littoralis var. Holub, Tidestromia carnosa, T. lanuginosa and T. valdesiana Sanch. (2007) who examined a large number of Alternanthera spp. Bayesian analysis was conducted with the program MrBayes v3.1.2 (Ronquist & Huelsenbeck, 2003). However, the relation between nematode density and plant weight, as found in the experiments, could be explained without having recourse to this hypothesis, by assuming that the invasion necrosis retarded the development of the plants and delayed the moment tuber formation began but did not influence the growth of the tubers. are annual or perennial herbs, shrubs, small trees or rarely vines (Robertson, 1981; Borsch, 2001). Data were partitioned into the rpl16 intron (group II), rpl16 exon, trnL intron (group I), trnL-F spacer and ITS with an individual model assigned to each partition. All analyses indicated the monophyly of the genus Alternanthera. Ca2+ concentration increased with 35, 185 and 975 eggs/g soil, leading to an increased Ca/K ratio with 185 and 975 eggs/g soil, which was in accordance with the reduction of water consumption/g haulm/day, observed with the same nematode numbers. Diurnal temperature fluctuations did not have a differing influence on germination rates or final germination percentages compared with constant temperatures. Experiments were conducted under greenhouse conditions using five initial G. pallida soil infestation levels (0, 10, 20, 40, and 80 eggs/g soil). have been reported in the GalÃ¡pagos Islands (A. caracasana, A. lanceolata and A. sessilis; Eliasson, 1990) and nine are considered endemic to the GalÃ¡pagos (JÃ¸rgensen, 1999; Eliasson, 2004). Although distribution patterns in South and Central America, Mexico and the Caribbean are complex and biogeographical results will probably be strongly influenced by denser taxon sampling, the phylogenetic trees for Alternanthera suggest some specific biogeographical scenarios. The ITS tree congruently reveals the two major clades, Clades A (Node 6) and B (Node 1), and strongly supports the monophyly of Alternanthera (99% JK). Constant invariable characters were deactivated. The single MPT from the combined analysis using trnL-F and rpl16 data indicating sections proposed in Alternanthera by Martius (1826), Moquin-Tandon (1849) and Schinz (1934). Â© 1973, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY. maritima sister to A. crucis, in Clade B4 (Node 2, 96% JK; Fig. The latter is common in A. geniculata, A. olivacea and A. serpyllifolia as well as the outgroup taxa Pedersenia hassleriana. However, further taxon sampling is also needed to confirm the position of A. microphylla, which might in fact be resolved in the same clade but further away once all species are included, or ancient close C3 relatives might today be extinct. Flower arrangement along rachis. - contains a plants seeds.-The . In the early crop stages and especially in the clay soil experiments, banded N had a significant negative effect on the N uptake and DM yield compared to broadcast N, possibly due to salt damage. Personal narrative of travels to the equinoctial regions of the New Continent, during the years 1799-1804. Bentham & Hooker (1880) followed Moquin-Tandon's circumscription but differed in that they recognized only two of the three sections in Telanthera (Bucholzia and Brandesia) and two in Alternanthera (Allaganthera as already proposed by Moquin-Tandon and a new section Lithophila). 1. Topography and Geomorphology The Newey has red earth clay soils typical of the area. Two, A. serpyllifolia and A. geniculata, were formerly assigned to Brandesia by several authors (Martius, 1826; Endlicher, 1836â1840; Moquin-Tandon, 1849; Moore, 1895; Schinz, 1934; Fig. Flowers in Alternanthera can be sessile to short-pedicellate within the bracteoles. Taxa with polymorphic nucleotide sites and length polymorphisms in ITS. Darlu & Lecointre (2002), Lee (2001) and van der Niet & Linder (2008) suggested that the ILD test is still suitable as an explanatory method to detect significant incongruence and it produces more accurate results than other tests. In a given season, only a portion of the encysted eggs are stimulated to hatch and very few J2 hatch in the absence of a host. Because A. nesiotes is resolved in a subclade consisting of species that are distributed throughout the Americas (Clade B3; Fig. In all combinations fourth stage juveniles were mostly males. Lista comentada de las plantas vasculares de bosques secos prioritarios para l conservacin en los departamentos de Atlntico y Bolvar (Caribe colombiano Dinmica sucesional de un fragmento de bosque seco tropical del Valle del Cauca Colombia Dinmica de la vegetacin en un … Biological activities of different parts of the plant reported include anti-microbial, antioxidant, anti-inflammatory, analgesic, anti-diabetic, cytotoxicity, hepatoprotective, anti-cancer, larvicidal and piscicidal activity. Within Clade B, Subclades B3 and B4 (Node 7, Fig. Hatching factors with activity towards Globodera rostochiensis were isolated from the root leachates produced by 1500 potato plants grown in gravel. Alternanthera tenella was considered to be widespread at relatively low elevations through many parts of the Neotropics (Borsch, 2001), and in light of our trees does not appear to be monophyletic. To account for possible reticulate speciation and incomplete lineage sorting in a group with unreliable species classification, the same individuals were used for each data set, with the exceptions of Tidestromia carnosa (Steyerm.) Double-stranded DNA templates were amplified for two plastid regions (rpl16, trnL-F) and nuclear ITS. The close relationship between these species was noted by others (e.g. Seedlings: Cotyledons are hairless and oval; leaves initially form in a basal rosette. 1]. In all three species, imbibition rate and extent were reduced with decreasing Î¨, causing a prolonged lag-phase before germination, particularly in Kentucky bluegrass. maritima in trees derived from biparentally and maternally inherited markers suggests a possible hybrid origin. 0 = long, 1 = short. Although the model described the full range of temperature, it was tested for the range from 0 to about 30Â°C. Amendment of soil with T. harzianum significantly reduced Pf/Pi of G. pallida by 42-47% in the potato-following-potato but not in either the potato-after-fallow nor in the potato-after-S. sisymbriifolium cycles which supports evidence that the plant species may play a role in the biocontrol activity of this fungus. Knowledge of the host range of this nematode is limited, with only tomato (Solanum lycopersicum) and potato (Solanum tuberosum) reported as hosts. of each population was normal, except for lentil where it was log-normal. Gowik et al., 2006). Eliasson (1985, 1990, 2004) already hypothesized that two or three GalÃ¡pagos Alternanthera spp. Rob.) DNA extraction from herbarium material included 30 ÂµL of Î²-mercaptoethanol and 30 ÂµL of highly purified proteinase K solution (Roche) added to the recommended 400 mL of AP1 lysis buffer with constant mixing and incubation at 42 Â°C for 12â24 h based on the methods of Motley, Wurdack & Delprete (2005). Our results corroborate the hatch-inducing effect of S. sisymbriifolium, underline the importance of growth duration and root length density as determinants of the reduction in PCN population that can be achieved and draw attention to the pitfall in methodology that can arise in the study of hatch stimulation. Among these âJamesbondiaâ spp., A. geniculata has stipitate flowers [homoplasious character 4(1); Â Appendix 2], whereas A. olivacea has sessile flowers. Although conditions of culture and storage of the nematodes, production of the diffusate and methods of hatching were standardised, there were differences in the proportion of viable eggs that hatched. Exposure of G. pallida to B. juncea seed meal extract at 4.5 t/ha reduced egg hatch by 90% compared with a nonamended control. However, A. kurtzii, which is the sister group, is most likely of hybrid origin (parental taxa are unknown); thus, the more derived position of the putative C3âC4 intermediate taxa in the plastid tree may not depict the true origin of this photosynthetic pathway if a C3 species is the paternal parent and C3 is dominant. maritima with six other species in Clade B3 (Node 3, 97% JK; Fig. ; Figs 1, 2] which have an erect habit, flowers usually arranged along a rachis to form slender spicate inflorescences, and are predominately distributed in Central America and the Caribbean islands. and found that 17 (19.5%) had C4 metabolism. We are very grateful to Damon Little (NYBG) for assistance in obtaining most of the ITS sequences of Alternanthera. Supply and stacking of plant Euphorbia caracasana (bronze colour leaves) of height 60-75 cm. The polymerase chain reaction (PCR) was performed with 25-ÂµL reactions containing 1 Ã Taq buffer with 1.5 mm MgCl2, 1 mm dNTP mix (2.5 mm each), 0.4 Âµm of each primer, 1 U Taq DNA polymerase (Qiagen) and 1 ÂµL of DNA template. The review provides data on sources of potato resistance to parasitic nematodes identified in collections of wild and cultivated species. In comparison with control plants, AMF-inoculated plants accelerated the in vitro hatch (21% mean increase) of the potato cyst nematode (PCN) species Globodera pallida (but not of G. rostochiensis) in potato root leachate collected 3 weeks after shoot emergence. Alternanthera littoralis (= A. maritima) grows in moist dunes, with three varieties considered to be vicariant along the coasts of the Caribbean, South America and western tropical Africa, respectively (Pedersen, 1990), and has succulent leaves without Kranz anatomy (T. Borsch, pers. Â© 2008-2021 ResearchGate GmbH. Potato cyst nematodes (PCN) have been known to occur in the UK for nearly a hundred years. 0 = absent, 1 = present. Alternatively, in the nrITS tree (Fig. To obtain insight into the phylogenetic distribution of currently known types of photosynthetic pathways in Alternanthera, data were taken from published works. This group corresponds to A. caracasana, A. chacoÃ«nsis, A. filifolia, A. flavicoma, A. galapagensis, A. geniculata, A. halimifolia, A. macbridei, A. littoralis var. The duration from seed soaking to the appearance of the first leaf depended linearly on water temperature, with a base temperature of about 8Â°C. 7 vols. Three check cultivars were replicated four times per date, and the others were not replicated. or H. pallida Stone. Differences in germination response to environmental conditions often result in different establishment success. After an additional 16 weeks, few cysts were found in the potato-after- S. sisymbriifolium treatments regardless of initial infestation rate. into English by Helen Maria Williams. Striga asiatica (Scrophulariaceae) is a parasitic plant requiring a host-derived signal, xenognosin, to initiate a cascade of events necessary for the establishment of host contact. Alternanthera galapagensis is the closely related sister species to A. crucis and the five bushy species from the GalÃ¡pagos. PP distributions of trees and branch lengths were obtained using the Markov Chain Monte Carlo (MCMC) method (Metropolis et al., 1953; Hastings, 1970) and transferred on the resulting phylogenetic trees. One regards the colonization of the GalÃ¡pagos Islands and the subsequent radiation of species. Unfortunately, our samples of A. tenella were not included in any physiological study, so their precise photosynthetic pathway is not known. Howell (1933) and Eliasson (1971) suggested that A. snodgrassii is closely related to A. vestita. progress curves in 33 different hydrothermal environments (8â26Â°C and 0 to â1.2 MPa) could be described according to a new To read the full-text of this research, you can request a copy directly from the authors. Eco-regions are defined as areas where the type, quality and quantity of environmental resources are generally similar. To clarify species limits further, a geographically representative sampling of populations from both entities will be needed. The effects of planting date and growing period of potato cultivars on their efficiency as trap crops for potato cyst nematodes (PCN) were studied. The grass Setaria parviflora has been naturalized in the Šibenik area (Solaris, Zablaće) for some time now but the grass Bromus catharticus has been found only recently, in Zadar (Voštarnica). The decline of Globodera rostochiensis (Woll.) Alternanthera tenella is sister taxon to the species from the GalÃ¡pagos and A. crucis. of the group the authors prefer to retain the family name Chenopodiaceae in addition to Amaranthaceae] are the major lineage with C4species in eudicots (Kadereit et al., 2003; Sage, Christin & Edwards, 2011). A pure correlation of such primary research data to our individuals here identified as A. tenella is in such a situation rather speculative.
