Genetic relationships in the genus Cicer L. as revealed by polyacrylamide gel electrophoresis of seed storage proteins

Total seed storage protein of the cultivated chickpea, C. arietinum L., and eight other wild annual Cicer species (all 2n = 16) was separated and compared by sodium dodecyl sulphate polyacrylamide gel electrophoresis. The seed-protein profile was a conservative and species-specific trait. Relative i...

Description
Summary:Total seed storage protein of the cultivated chickpea, C. arietinum L., and eight other wild annual Cicer species (all 2n = 16) was separated and compared by sodium dodecyl sulphate polyacrylamide gel electrophoresis. The seed-protein profile was a conservative and species-specific trait. Relative interspecific similarities of protein patterns were estimated using Jaccard's similarity index, and a cluster analysis was performed. The resultant dendrogram generally agreed with the limited data already available on interspecific relationships in Cicer based on morphological characteristics, crossability, genome pairing in hybrids, karyotypes and isozyme analysis. The difference between the profiles of C. judaicum and C. pinnatifidum supported the idea that they are indeed two separate species. The closest relative of C. arietinum was C. reticulatum, followed by C. echinospermum and other species, while C. cuneatum was the farthest relative. In general, C. cuneatum was also genetically the farthest removed from any other species. The suggestion that C. reticulatum is the wild progenitor of the cultivated chickpea was therefore further supported.
