Total seed protein variability in a sample of 163 entries of year-bean (Phaseolus polyanthus), including wild, feral and cultivated forms of the whole range of distribution in Latin America was studied using 1-dimensional SDS/PAGE and 2-dimensional IEF-SDS/PAGE. Ten different patterns were observ...

A geographic frequency distribution of seed protein patterns of 306 individuals belonging to Phaseolus polyanthus is presented. Plant material covered the range of distribution of P. polyanthus from Veracruz, Mexico to Cajamarca, Peru. (CIAT)


Debouck, Daniel G.Schmit, VéroniqueLibreros, DimaryRamírez, Hernando[Biochemical evidence for a fifth cultigen within the genus Phaseolus]Biochemical evidence for a fifth cultigen within the genus Phaseolus

A total of 96 accessions (82 cultivated and 14 wild) of lima beans, Phaseolus lunatus, from CIAT`s collection, were analyzed for their seed`s CP composition. So far, 2 major families of electrophoretic patterns can be distinguished in the cultivated materials, showing that they come from 2 differ...


Debouck, Daniel G.Maquet, A.Posso, C.E.[Biochemical evidence for two different gene pools in lima beans, Phaseolus lunatus L]Biochemical evidence for two different gene pools in lima beans, Phaseolus lunatus L

Background: The wild relatives of crops represent a major source of valuable traits for crop improvement. These resources are threatened by habitat destruction, land use changes, and other factors, requiring their urgent collection and long-term availability for research and breeding from ex situ...
