Tribes Trifolieae and Vicieae along with Cicereae and Galega (Galegeae) form a monophyletic group that has been designated informally as the “vicioid clade”. There is good support from analyses of various molecular data for the clade itself, but relationships of genera within the clade are not fully understood nor has monophyly of the tribes and genera been fully tested. Sequences of the plasti...

Earlier studies [1, 2] have demonstrated that a number of isoflavonoid (pterocarpan) phytoalexins [3] accumulate in excised, fungus-inoculated leaflets of species belonging to the genus Lathyrus (Leguminosae-Papilionoideae; tribe Vicieae). Apart from pisatin (3-methoxy-6a-hydroxy-8,9-methylenedioxypterocarpan, 1), the most commonly en­ countered Lathyrus phytoalexin, small quantities of three o...

this project was conducted to study the taxonomy of tribe vicieae based on morphological characters. the specimens were collected from different parts of khorassan, and after identification they were preserved at ferdowsi university of mashhad herbarium (fumh). diagnostic keys and a complete list of distribution regions for all species of this tribe in khorassan were presented. cicer kermanense...

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...

Although pterocarpan phytoalexins commonly ac­ cumulate in the fungus-inoculated tissues of papilionate legumes, only three compounds of this type possess oxygenation at C-2 [1, 2]. They are 2,3,9-trimethoxypterocarpan (1), 2,9-dimethoxy-3-hydroxypterocarpan (2-methoxymedicarpin, 2) and 2,3,9-trimethoxy-4-hydroxypterocarpan (3) all of which co­ occur with pisatin in the Fusarium solani f. sp. p...
