Distribution of the protein “phaseolin“ in some representatives ofViciaceae

Abstract

Using immunochemical methods the authors investigated the evolutionary taxonomic distribution of the reserve seed protein “phaseolin” in cultivars ofPhaseolus vulgaris, in a series of species ofPhaseolus, and in representatives of some additional genera ofViciaceae. “Phaseolin” is typical of the seed ofPhaseolus vulgaris L.: it was detected in all 658 investigated cultivars — and also in species related toPhaseolus 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 ofPh. vulgaris L. -Ph. coccineus L.). A protein immunochemically somewhat similar to „phaseolin“ occurs inPh. acufifolius A. Gray. In all other taxa“phaseolin” is absent.
