Molecular phylogenies provide a framework to discuss relationships in the vast temperate herbaceous radiation of papilionoid legumes comprised of tribes Galegeae, Carmichaelieae, Cicereae, Hedysareae, Trifolieae, Vicieae, as well as among some members of the tropical tribe Millettieae (Callerya, Wisteria, and related genera). The taxa form a monophyletic group marked by the loss of the chloropl...
Most species in the Leguminosae (legume family) can fix atmospheric nitrogen (N₂) via symbiotic bacteria (rhizobia) in root nodules. Here, the literature on legume-rhizobia symbioses in field soils was reviewed and genotypically characterised rhizobia related to the taxonomy of the legumes from which they were isolated. The Leguminosae was divided into three sub-families, the Caesalpinioideae, ...
خصوصیات خامه 35 گونه شامل 26 گونه از Lathyrus ، 3 گونه از Pisum، 4 گونه از Vicia و 2 گونه از Lens با استفاده از میکروسکوپ الکترونی (SEM) بررسی شدند. نتیجه بررسی میکرومورفولوژی نشان داد که چهار جنس Lathyrus, Lens, Vicia و Pisum در ویژگیهای خامهای، متفاوت هستند. حداقل هشت نوع خامه در قبیله Fabeae حضور دارد. چهار نوع از این خامهها (1) خامه صاف، خطی و کرکها یکنواخت (Sle-type) (2) خامه صاف، قاشقی...
Evolutionary relationships were inferred among a worldwide sample of Ascochyta fungi from wild and cultivated legume hosts based on phylogenetic analyses of DNA sequences from the ribosomal internal transcribed spacer regions (ITS), as well as portions of three protein-coding genes: glyceraldehyde-3-phosphate-dehydrogenase (G3PD), translation elongation factor 1-alpha (EF) and chitin synthase 1...
The establishment of the nitrogen-fixing symbiosis between rhizobia and legumes requires an exchange of signals between the two partners. In response to flavonoids excreted by the host plant, rhizobia synthesize Nod factors (NFs) which elicit, at very low concentrations and in a specific manner, various symbiotic responses on the roots of the legume hosts. NFs from several rhizobial species hav...
