A revised classification of the tribe Phaseoleae (Leguminosae: Papilionoideae), and its relation to canavanine distribution

Abstract

The subtribal classification of the tribe Phaseoleae has drifted into disorder since Bentham's (1865) scheme in the Genera Plantarum. A revised classification is here proposed, which for the first time accounts for all of the currently recognized genera. This classification has seven subtribes: Cajaninae, Diocleinae, Kennediinae, Phaseolinae, Glycininae, Ophrestiinae, and Erythrininae, of which the Ophrestiinae is new. A survey for the free amino acid, canavanine, shows that it is most often present in the Diocleinae and Kennediinae and frequently absent in the rest of the tribe.

Resolution of polyphyly in Pueraria (Leguminosae, Papilionoideae): The creation of two new genera, Haymondia and Toxicopueraria, the resurrection of Neustanthus, and a new combination in Teyleria

“…Lackey also recognized that species in group B were distinct enough from group A to warrant the creation of a new genus. Lackey also suggested that group D should be excluded from Pueraria based on morphology (1977b) and, in particular, that P. wallichii was anomalous in the genus based on the presence of canavanine, a non-proteinogenic α-amino acid (Lackey, 1977a). In spite of all these recommendations, Lackey did not formally revise the genus according to his groupings.…”

Distribution of Leaf Flavonoid Aglycones and Glucuronides in the Genus Phaseolus and Related Genera

“…For example, seed extracts of Lathyrus yielded amino acid patterns which reflect species differences (Bell, 1962). Lackey presented a classification of the tribe Phaseoleae based on canavanine amino acid distribution in seeds of species (Lackey, 1977). Ingham studied the systematic significance of phytoalexin compounds in the Phaseoleae (Ingham, 1990).…”

Genetic Diversity of Bulgarian Phaseolus vulgaris L. Germplasm Collection Through Phaseolin and Isozyme Markers

“…It in turn is a member of the tribe Phaseoleae of the subfamily Papilionoideae and the family Leguminosae (Fabaceae) (van Eseltine, 1931;in Lackey, 1977;Maréchal et al, 1978). The neotropical genus Phaseolus includes about 50 to 60 species of wild bean (Toro et al, 1990), most of them distributed in Mesoamerica, five of which are cultivated: P. vulgaris (L.) Savi (common), P. dumosus Macfady (tepari), P. coccineus L. (multicolored, scarlet-coloured), P. lunatus L. (Lima) and P. polyanthus Green (Debouck, 1989;Caicedo et al, 1999;Delgado-Salinas et al, 1999;Gutiérrez Salgado et al, 1995).…”
