Distribution of the protein “phaseolin“ in some representatives ofViciaceae

Using immunochemical methods the authors investigated the evolutionary taxonomic distribution of the reserve seed protein “phaseolin” in cultivars of Phaseolus vulgaris , in a series of species of Phaseolus , and in representatives of some additional genera of Viciaceae. “Phaseolin” is typical of the seed of Phaseolus vulgaris L.: it was detected in all 658 investigated cultivars — and also in species related to Phaseolus vulgaris L. (Ph. vulgaris L. ssp. aborigineus Burk., Ph. polyanthus Green, Ph. dumosus Macf., Ph. coccineus L., and in an undescribed species from the group of Ph. vulgaris L. - Ph. coccineus L.). A protein immunochemically somewhat similar to „phaseolin“ occurs in Ph. acufifolius A. Gray. In all other taxa“phaseolin” is absent.
