| 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 |
| lathyrus saponin, a new trisaccharide glycoside from lathyrus japonicus. | a new triterpenoid saponin, named lathyrus saponin (3), was isolated from the whole plant of lathyrus japonicus willd. together with two known saponins, azukisaponins ii (1) and v (2). as their methyl esters. the structure of 3 was determined to be soyasapogenol b 3-0-beta-d-glucopyranosyl(1-->2)-beta-d-glucopyranosyl(1-->2)-beta-d-glu curonopyranoside on the basis of physicochemical and spectroscopic methods. | 1998 | 9548865 |
| 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 |
| nutrient distribution and phenolic antioxidants in air-classified fractions of beach pea (lathyrus maritimus l.). | beach pea (lathyrus maritimus l.) cotyledons and hulls were air-classified into different fractions. the crude protein content (%n x 6.25) of samples ranged from 32.8 to 35.3% in cotyledons and 14.7 to 16.8% in hulls. crude fiber content was higher in hulls fraction 1 (37.13%) and fraction 2 (36.85%) than in cotyledons (2.83, 2.99, and 3.08% in fractions 1, 2, and 3, respectively). condensed tannins of cotyledons ranged from 5.76 to 6.90% and of hulls ranged from 52.49 to 57.24%, expressed as ca ... | 2001 | 11262051 |
| seasonal changes in oleosomic lipids and fatty acids of perennial root nodules of beach pea. | seasonal changes in the fatty acid composition of phospholipids (pl), monoglycerides (mg), diglycerides (dg), free fatty acids (fa) and triglycerides (tg) separated from oleosomes (lipid bodies) of perennial root nodules of beach pea (lathyrus maritimus) were analysed. thin layer chromatography (tlc) revealed that pl and mg are the major lipids in nodule oleosomes. the fatty acid profile and overall double bond index (dbi) varied among lipid classes depending upon the season. high dbi in pl and ... | 2003 | 12756915 |
| seasonal changes in carbohydrates of perennial root nodules of beach pea. | seasonal changes in amyloplast, starch, total soluble sugars, non-reducing sugars and reducing sugars of perennial root nodules of beach pea (lathyrus maritimus) were studied. ultrastructural changes in nodule cells of beach pea indicated an accumulation of large amounts of amyloplasts with multiple starch grains in summer months. as the winter season sets in, degradation of amyloplasts and starch grains was detected. the membranes of amyloplasts faded out in winter and the structure of the amyl ... | 2003 | 14610887 |

| genotypic and phenotypic diversity of rhizobia isolated from lathyrus japonicus indigenous to japan. | sixty-one rhizobial strains from lathyrus japonicus nodules growing on the seashore in japan were characterized and compared to two strains from canada. the pcr-based method was used to identify test strains with novel taxonomic markers that were designed to discriminate between all known lathyrus rhizobia. three genomic groups (i, ii, and iii) were finally identified using rapd, rflp, and phylogenetic analyses. strains in genomic group i (related to rhizobium leguminosarum) were divided into tw ... | 2010 | 20851546 |
| interactions between resources and abiotic conditions control plant performance on subarctic coastal dunes. | both abiotic conditions and resource levels affect the performance of plants on coastal dune systems. on the foredune, environmental factors are particularly limiting for plant growth and these vary along a short topographical gradient, from the foot to the ridge. on subarctic coastal dunes in northeastern canada, this topographical gradient is paralleled by a plant sequence that typically involves honckenya peploides, elymus mollis, and lathyrus japonicus. in this study, field nutrient addition ... | 1997 | 21708578 |
| isolation and characterization of microsatellite loci in the beach pea, lathyrus japonicus (fabaceae), in japan. | • premise of the study: microsatellite loci were developed for lathyrus japonicus (fabaceae) to evaluate genetic diversity, population genetic structure, and demographic patterns of this species in japan. • methods and results: in total, eight primer sets were identified in japanese populations of l. japonicus and polymorphisms were evaluated in 83 individuals from three populations, including the northern and southern geographic range in japan. the number of alleles per locus ranged from four t ... | 2011 | 22106441 |
| isolated history of the coastal plant lathyrus japonicus (leguminosae) in lake biwa, an ancient freshwater lake. | lake biwa is one of the world's few ancient lakes. formed ∼4 million years ago, the lake harbours many coastal species that commonly inhabit seashores. the beach pea lathyrus japonicus is a typical coastal species of this freshwater lake, but its inland populations are faced with the threat of extinction. here, we investigated the phylogeographical and population structures of both inland and coastal populations of l. japonicus. we also elucidated the historical isolation of the lake biwa popula ... | 2011 | 22476491 |
| rhizobium anhuiense as the predominant microsymbionts of lathyrus maritimus along the shandong peninsula seashore line. | beach pea [lathyrus maritimus bigelow, or lathyrus japonicus subsp. maritimus (l.) p.w. ball] is a wild legume distributed on the seashore line, and the rhizobia nodulating with this plant have been reported only rarely. in order to reveal the diversity of beach pea rhizobia on the seashore line of shandong peninsula, china, a total of 124 bacterial strains were isolated from the root nodules of beach pea plants collected from five sites. all the isolates were divided into five reca types after ... | 2016 | 27480059 |
| plant species introduced by foreigners according to folk tradition in norway and some other european countries: xenophobic tales or not? | in their quest to understand and interpret nature, people have frequently sought religious or divine origins for plant species and their characteristics. less often, historical events or persons are involved. this study comprises eleven cases of the latter kind, all claiming that plant species have been introduced by foreigners or at least from foreign lands. | 2015 | 26438411 |
| a new species of megoura (hemiptera, aphididae) from japan. | a new species of the genus megoura, m. lathyricola sp. n., was collected from lathyrus japonicus subsp. japonicus (leguminosae) in seashore areas of northern and southern japan. this species is described and illustrated, and a revised key to the identification of the world species of megoura is presented. | 2014 | 25061353 |
