| classification of bacteria nodulating lathyrus japonicus and lathyrus pratensis in northern quebec as strains of rhizobium leguminosarum biovar viciae. | the diversity of two populations of rhizobia isolated from lathyrus japonicus (30 strains) and lathyrus pratensis (49 strains) growing in northern regions of quebec, canada, was determined on the basis of phenotypic characteristics, multilocus enzyme electrophoresis, dna-dna homology, and 16s ribosomal dna sequencing. according to numerical analysis of phenotypic characteristics, strains were divided into four groups. strains isolated from l. pratensis fell in groups i to iii; the latter include ... | 1996 | 8863431 |
| physiological adaptation to low temperatures of strains of rhizobium leguminosarum bv. viciae associated with lathyrus spp.(1). | strains of rhizobium leguminosarum bv. viciae, isolated from the legume species lathyrus japonicus and lathyrus pratensis in northern quebec (canada), showed different capacities for growing at low temperature. in the present study, we investigated some mechanisms related to cold adaptation. two cold-adapted strains (psychrotrophs) were compared to a poorly adapted strain and to a cold-sensitive strain (reference strain) for freezing survival, protein induction and fatty acid composition under l ... | 2000 | 10817864 |
| effects of bacterial secondary symbionts on host plant use in pea aphids. | aphids possess several facultative bacterial symbionts that have important effects on their hosts' biology. these have been most closely studied in the pea aphid (acyrthosiphon pisum), a species that feeds on multiple host plants. whether secondary symbionts influence host plant utilization is unclear. we report the fitness consequences of introducing different strains of the symbiont hamiltonella defensa into three aphid clones collected on lathyrus pratensis that naturally lack symbionts, and ... | 2011 | 20843842 |
| an investigation into the antifungal property of fabaceae using bioinformatics tools. | chemodiversity in plants provides sources of great value which might be helpful for finding new leads in drug discovery programs. fabaceae as the third largest family of flowering plants was chosen to investigate its possible antifungal activity. in order to increase the effectiveness of the result, molecular similarity methods and chemical data were used. twelve plants were selected from fabaceae and collected from the north and south of iran. percolation method with 80% ethanol was used for ex ... | 2010 | 23407751 |
| [characteristics of natural selection in populations of nodule bacteria (rhizobium leguminosarum) interacting with different host plants]. | using high throughput sequencing of the noda gene, we studied the population dynamics of rhizobium leguminosarum (bv. viciae, bv. trifolii) in rhizospheric and nodular subpopulations associated with the leguminous plants representing different cross-inoculation groups (vicia sativa, lathyrus pratensis of the vetch/vetchling/pea group and trifolium hybridum of the clover group). the "rhizosphere-nodules" transitions result in either an increase or decrease in the frequencies of 10 of the 23 opera ... | 2015 | 27169225 |
| volatile fingerprints of seeds of four species indicate the involvement of alcoholic fermentation, lipid peroxidation, and maillard reactions in seed deterioration during ageing and desiccation stress. | the volatile compounds released by orthodox (desiccation-tolerant) seeds during ageing can be analysed using gas chromatography-mass spectrometry (gc-ms). comparison of three legume species (pisum sativum, lathyrus pratensis, and cytisus scoparius) during artificial ageing at 60% relative humidity and 50 °c revealed variation in the seed volatile fingerprint between species, although in all species the overall volatile concentration increased with storage period, and changes could be detected pr ... | 2012 | 23175670 |
