(149785), a grant from the American Society of Plant Taxonomy to I.S.P., a grant from Ciencia Básica CONACYT for I.S.P. 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. To clarify species limits further, a geographically representative sampling of populations from both entities will be needed. 10. In fact, Carlquist (1974) indicated that Galápagos Alternanthera spp. Species of Alternanthera have a capitate stigma which never has two evident deeply lobes as in the outgroup taxa. pedicellate flowers [character 4(1);  Appendix 2] and crenate pseudostaminodia [character 7(1);  Appendix 2]. G. rostochiensis Ro1 and G. pallida Pa2 invaded less numerously and few developed to the third stage. Soil fumigation with the nematicide Telone II (1,3-dichloropropene; Dow Agro-Sciences) is being conducted in infested fields as part of the G. pallida eradication program, and Solanum sisymbriifolium 'litchi tomato' is under field-scale trials in infested fields (USDA-APHIS 2019). Style length. We have identified several (a)biotic stress-responsive genes of unknown function in Amaranthus hypochondriacus, including the so-called Ah24 gene. A series of field experiments was carried out to study actual root length distribution of S.¿sisymbriifolium in relation to shoot properties and to provide input into the model. The single MPT from the plastid DNA data sets shows that A. crucis, A. filifolia, A. flavicoma, A. halimifolia, A. snodgrassii and A. vestita were grouped together in a weakly supported clade (62% JK). The PNW spans three ecoregions as defined by Omernik (1987) and outlined by the Commission for Environmental Cooperation (1997). However, available recent studies of Alternanthera were limited, either regionally (in the context of treatments for national floras) and in the analysis of only gross morphological characters. Statistical values of the sequences included in the molecular matrices are summarized in Table 2. The simple form was the most common for the sampling. All model parameters can be readily determined for a given cultivar from well-defined experiments conducted in controlled environments. Golden Wonder) tubers with AMF eliminated this delay in G. pallida hatch by stimulating a mean increase of 32% (P < 0.01) in hatch within 2 wk after planting. Grafted plants were more vigorous, as measured by plant height, main stem diameter, and root system weight, than the nongrafted 'Tsakoniki'. A mechanized system which separated roots from soil materials was constructed which combines the kinetic energy of pressurized spray jets and the low energy of air flotation. Personal narrative of travels to the equinoctial regions of the New Continent, during the years 1799-1804. By attempting to model the distribution of the xenognosin around the host, the activity of the signal is shown to be strongly dependent on the presence of another component in the host exudate. Peetz, A. The soil cores collected in the first 2 weeks after plant emergence contained significantly greater hatching activity towards G. pallida than G. rostochiensis, indicating that G. pallida-selective hatching factors were produced by the host crop earlier than G. rostochiensis-selective hatching factors. nama latin Globodera rostochiensis (Woll.) Traditional classifications proposed for the genus Alternanthera and related genera. 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. Flowers in Alternanthera can be sessile to short-pedicellate within the bracteoles. These species also share a preference for aquatic environments. Crop rotation with a resistant potato cultivar was very effective in decreasing the population density of G. rostochiensis in soil. 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. I. Flower insertion. To assess the effect of temperature on germination rates, the reciprocal of the duration (1/duration) for 50% germination was calculated and regressed against temperature. Lines such as IR13240-108-2-2-3, which is adapted to several seasons, were comparatively insensitive to photoperiod and temperature. A previous study presented a model that disaggregates photothermal effects on rice phenology for the different crop development stages and the two main factors, daylength and temperature. In this study, congruence among data sets was evaluated observing topological congruence (Figs 1, 3). Oospore germination from two Scandinavian (A1 and A2) P. infestans isolates was stimulated in visible light and in 1 : 2 and 1 : 10 soil extract. Then listen and check. Rate of rhizome bud break was higher than for seed germination at temperatures of 32 C or below, but lower at higher temperatures. Alternanthera caracasana and A. pungens are sister species, which share many morphological characteristics. Previous work has shown the two species, Globodera rostochiensis and G. pallida, to be distributed throughout the UK. It is known that the organisms best adapted for long-distance dispersal are weedy plants (Carlquist, 1965). We considered each of these processes separately when simulating the combined effect of temperature and seeding depth on seedling emergence. The effect of light and nutrients on oosporogenesis is discussed. DiTera® (Valent BioSciences Corp.), a novel biological nematicide obtained from fermentation with a hyphomycete fungus, adversely affected activity and movement through sand columns of second stage juveniles (J2) of Globodera rostochiensis. Parsimony analysis of the nuclear ITS data resulted in three MPTs of 788 steps in length (CI = 0.55, RI = 0.80). Based on a single exponential decay function, a general method is presented to estimate for any PCN management measure the average reduction in the number of years needed to ensure that the PCN population falls below a given density. Schinz, A. flava (L.) Mears, A. lanceolata, A. macbridei and A. porrigens Kuntze supported by the homoplasious character of long style [character 6(0);  Appendix 2] with a reversal condition for A. pubiflora, which is supported by the presence of short styles [character 6(1);  Appendix 2]. Low divergence was found in the 5.8S gene with only nine potentially parsimony-informative characters (representing 55.2% of the variable sites). 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. This may reflect the different coevolutionary histories of nematodes and their Solanum hosts in South America. In the plastid DNA tree it diverges second after A. microphylla in clade B3 (Fig. 1), which was sister to A. laguroides. The relevance of the same model to two unrelated species from different climates and of different ecological behaviour suggests that it may be generally useful in determining optimum temperatures for seed viability testing regimes and ultimately for predicting field behaviour A power-law model was used to fit G. pallida dispersal capabilities. To test for reticulate patterns in evolution of species diversity, trees from the nuclear ribosomal internal transcribed spacer (nrITS) region were compared with trees inferred from data sets of the highly performing non-coding plastid regions trnL-F and rpl16. Over seventy years much effort has been expended by many groups to isolate these agents and to determine their structures. When these samples were fractionated on Sephadex G-10 by low pressure liquid chromatography and the fractions tested for hatching activity, the non-sterile PRL produced more hatching factors (HF) than the sterile PRL; in the fractionated sterile PRL only one significant HF (active towards G. pallida) was observed, compared to six (towards G. pallida) and three (towards G. rostochiensis) HF from the non-sterile PRL, with two HF being active towards both species. Sequence variation among the trnL-F, rpl16 and ITS regions. The highest diversity is found in South America (Mears, 1977), but many species also occur in the Caribbean, Central America and Mexico. (= Section Trommsdorffia) were transferred to Iresine P.Browne (Endlicher, 1836–1840; Moquin-Tandon, 1849; Bentham & Hooker, 1880; Schinz, 1893, 1934; Townsend, 1993). has been suggested as a trap crop for potato cyst nematodes in The Netherlands (Scholte, 2000a,b; Scholte and Vos, 2000). Tolerance limits were 1.5 eggs per g of soil for 'Libertas' at low nitrogen fertilizer level and 6 eggs per g of soil for 'Multa' at the same fertilizer level. We thank Zachary Rogers (MO) who greatly helped to improve the English text, Joseph Rachlin (Lehman College, CUNY), Henrik Nilsson (GB) and two anonymous reviewers for valuable comments on the manuscript, and Uno H. Eliasson (GB) for access to his material of Alternanthera from the Galápagos Islands. Alternanthera as currently widely accepted goes back to Schinz (1893), later adopted by Townsend (1993) who circumscribed the genus like Moquin-Tandon (1849) but excluded Pedersenia (for an overview of classification systems see Table 1). Eggplant (Solanum melongena L.) seedlings ('Tsakoniki') were grafted by hand on the Verticillium dahliae Kleb. The circumscription of Alternanthera has varied considerably (Table 1) over time among different authors. Along the same lines, Mears's annotations on herbarium specimens show that he considered A. flavicoma to be a subspecies or form of A. filifolia, but a nomenclatural change was never published. Amaranth is an ancient crop in which interest is being renewed, due to its adaptability, stress tolerance, and nutritional value. The polymerase chain reaction (PCR) was performed with 25-µL reactions containing 1 × Taq buffer with 1.5 mm MgCl2, 1 mm dNTP mix (2.5 mm each), 0.4 µm of each primer, 1 U Taq DNA polymerase (Qiagen) and 1 µL of DNA template. Methods However, all attempts have failed. The goal of this research was to evaluate the hatching effect of root exudates from Solanum sisiymbriifolium (cvs Sharp, Pion, Sis 4004 e Domino) on five Meloidogyne isolates (M. arenaria, M. chitwoodi, M. hapla, M. hispanica and M. javanica) and to contribute for the development of an alternative strategy to the use of the nematicides. 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. As non-herbivorous nematodes contribute to decomposition, nutrient mineralization, microbial community structuring and control of herbivorous insect larvae, we also review the impact of plant metabolites on these non-target organisms. When potato followed barley, numbers of cysts were similar to those found after a single cycle of potato, indicating that the barley crop had no effect on the survival of initial inoculum. Alternanthera caracasana Kunth. Alternanthera tenella and A. crucis differ from all the Galápagos species by being herbaceous rather than woody. Porter (1984) confirmed this and pinpointed many colonizers from South America, in particular the Andean region. 0 = not keeled, 1 = prominently keeled. The topics considered include the Arrhenius equation and Q10; the collision and transition-state theories of the rate constant; models with a temperature optimum; models without a temperature optimum; phase changes; diffusion, viscosity and translocation; hybrid systems (biochemistry plus transport); photosynsthesis; respiration; and development with the day-degree hypothesis. Differential responses occur as revealed by specific susceptibilities of cultivars to certain pathogen genotypes and changing rank order. London: Longman, Hurst, Rees, Orme and Brown. All C3–C4 intermediates belong to a different clade that also contains C3 species, but species limits, including the widely studied A. tenella, are unclear. Overall, these results suggest that S. sisymbriifolium has potential to significantly reduce G. pallida populations, and also that the cropping system (i.e. maritima (Mart.) The extremes were the alpine species Dryas octopetala, which had a high Tb (c. 12.0 °C) and low S (26 degree days), and Saxifraga tridactylites which had a low estimated Tb (c. −1.8 °C) and a high S (136 degree days). In the laboratory, the effects were tested on germination rates at constant (9.1–21.8°C) and diurnally fluctuating temperatures at different soil water potentials. The TVM+G model of substitution was selected for the rpl16 intron and trnL-F spacer data sets, TIM+G for the rpl16 exon, K81uf+I+G for the trnL intron and the SYM+I+G model for the ITS partition. No significant correlation was found between tuber blight incidence under field conditions and the tuber blight rating in the National List. 4. merupakan nematoda Buds and soft fruits are also taken, causing considerable damage to agriculture. Soil was amended with P. cucumerina, T. harzianum or left unamended, and then infested with nematodes at a rate of five eggs g-1 of soil. The inland forested mountainous region found in the PNW is characterized by a transition from a moist, maritime climate in the west to a drier, continental climate in the east. This paper reports the results of the first structured and statistically unbiased survey undertaken to assess their occurrence and distribution in the potato growing land of England and Wales. chacoënsis. occurs along the east coasts of tropical America and three varieties in the west coast of tropical Africa (Pedersen, 1990). Thermal times to germination Within Clade B, there are four subclades (Clades B1–B4). These two species form a strongly supported clade (100% JK, 1.0 PP; Fig. The apparent N recovery increased by circa 20-25% (absolute). If C4 photosynthesis is coded as an individual unordered character state as in our study, a reversal from a C4 ancestor of Clade B3 to C3 photosynthesis in A. littoralis requires the same number of steps as an independent acquisition of C4 photosynthesis in A. microphylla, if optimized on the plastid DNA tree. Dilution tests showed that half strength PRD consistently stimulated highest levels of nematode hatch. This character is not applicable in A. brasiliana. in life form, Eliasson (1987) argued that the genus in the latter circumscription seems to be a natural taxon characterized by capitate stigmas and a dodecahedral pollen form. 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. Field trials were performed during 2 years using the following rotation: S. tuberosum cv. High numbers of cysts were recovered with potato. The ingroup contains 33 samples representing a total of 31 out of the c. 80–200 described Alternanthera spp. 6. This suggests that Alternanthera is another classic case of derived secondary woodiness associated with insular species (Carlquist, 1962, 1974, 2010a, b). Solanum integrifolium and its hybrids with eggplants were found to be highly tolerant to two to three strains. Hatching curves differed for cysts from the same population reared at the two locations. Chromosome evidence related to number and the form of meiotic division indicated hybridization in some members of Tidestromia (Sánchez-del Pino & Motley, 2010). the sequence of non-host and host plants) may play a significant role in the efficacy of fungal biological control agents. Assessing potato yield loss caused by the Idaho G. pallida population under field conditions was not performed due to its quarantine status in Idaho, where it is prohibited by regulatory statutes to grow potato in any infested fields. Easypeel) and distilled water were used as controls. As the temperature progressively increased, the percentage of seed that germinated rapidly increased to near 100%, whereas the duration for germination progressively decreased up to the thermal optimum. podantha of the Bromeliaceae and Aloe barbadense of the Asphodelaceae. For a better understanding of the evolution of photosynthetic pathways, it will be important to clearly document the plant materials studied biochemically and physiologically. Whereas C4 photosynthesis appears to have evolved in a single clade, the position of A. littoralis var. A single year with a cultivar carrying the H1 resistance gene reduced nematode populations by 62–95%. Recently, it is best known for its use as a trap crop for potato cyst nematodes (PCN).

Apart from A. macbridei Standl., this highly supported (99% JK, 1.0 PP; Fig. The Incongruence Length Difference (ILD) test (Farris et al., 1995) assesses character conflict between data sets and calculates the significance of that conflict. The morphological characters resolved as either homologous or homoplasious for this analysis are depicted in Figure 1. maritima and A. obovata. Schinz; character 9(1);  Appendix 2]. A resistant cultivar was grown in, Access scientific knowledge from anywhere. 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. Final R = 0.117 for 3721 observed reflections. Our results suggest that two major clades can be recognized within Alternanthera based on stigma surface, bracteole form and also inflorescence type. A seed rate of 100 m−2 seems generally sufficient. Three levels of soil compaction were made by different combinations of artificial compaction and rotary cultivation. The remaining species have a distinct midrib but never prominent so that bracteoles are flattened or convex. (2007) who examined a large number of Alternanthera spp. Galápagos Alternanthera spp. BROWN Hecklau, E. E, S. A. Mori, and J. L. Brown (Institute of Systematic Botany, The New York Botanical Garden, Bronx, NY 10458-5126; email: [email protected] org). The name A. ficoidea has indeed been the source of profound confusion (often with A. tenella) but could clearly be shown to be a synonym of A. paronychioides (Mears, 1977; Eliasson, 1987; Borsch, 2001), a distantly related C4 species. Species that have inflorescences either pedunculate or sessile are common in A. laguroides, A. olivacea, A. porrigens and A. pubiflora. Moquin-Tandon (1849) recognized infrageneric taxa based on sexual expression, stem habit, inflorescence type, stamen number and fusion, stigma shape, tepal features, style size and pseudostaminodium shape. They are characterized by subglobose to short-cylindrical inflorescences with dense solitary flowers, the stamens basally united in a cup and alternating with long, laciniate, small triangular or rarely obsolete pseudostaminodia and capitate stigmas (Eliasson, 1987; Townsend, 1993). 5. (range), percentage of pairwise sequence distance (uncorrected p distance, overall means, lowest and highest values in parentheses); ts/tv ratio, ratio of transitions to transversions; %var., percentage of variable positions; %inf. Some sections previously recognized for Alternanthera were elevated to the generic level [e.g. and A. serpyllifolia Urb. Schinz (1934) used the characters stamen filaments and pseudostaminodia shape as his diagnostic units. However, species with pedunculate inflorescences or both sessile and pedunculate inflorescences also occur in this clade [subclade B1 and A. philoxeroides (Mart.) This study suggests that it might be possible for Galápagos Alternanthera spp. Soil from each treatment (containing original cysts and newly-formed cysts when present) were then planted with potato. 12set) e d o n a ic r e m a it no a L lo ta I o s s e gr XX n o C RESUMOS Realização: COMISSÃO CIENTÍFICA DO CONGRESSO Coordenação: Dr. Ely Eduardo Saranz Camargo Realização: Responsável: Dr. Jaldo de Souza Santos Presidente do CFF SEÇÃO 1 ETNOMEDICINA E ANTROPOLOGIA APRESENTAÇÃO ORAL: Segunda-feira, 19 de setembro, das 16h00-18h00 … The temperature profiles for ITS amplifications were: one cycle at 97 °C for 50 s, 30 cycles each at 97 °C for 50 s, 53 °C for 50 s and 72 °C for 1 min 50 s, and a final extension at 72 °C for 7 min. We found that in addition to some floral characteristics (stigmatic characteristics resolved relevant clades in this study), the inflorescences types and life forms are important features in the taxonomy of the genus. These phenomena suggest that in the growth room only Seinhorst's 'second mechanism of growth reduction' was effective and that his 'first mechanism of growth reduction' (the main cause for yield losses in the field) was not operating. Several weedy Alternanthera spp. The main differences in the daughter ions produced from different hatching factors after fragmentation by mass spectrometry occurred between 245 and 500 Da. Selection for combined low thermal and photoperiod sensitivity, however, would be impractical on an experimental basis, and would therefore require genetic markers. Flowers make fruits. 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. Among this set, 12 were overexpressed when G. pallida was parasitizing S. tuberosum and 29 were overexpressed when parasitizing S. sisymbriifolium.
