Genetics of isozymes in grasspea.
We studied the inheritance and linkage of ACO-1, ACO-2, AAT-1, AAT-2, EST-3, EST-6, FDH, LAP-1, PGD-2, SKDH, and TPI-1 in four F2 populations of grasspea (Lathyrus sativus L.) using horizontal starch-gel electrophoresis. Mendelian inheritance was observed for all of the isozymes studied. All isozymes showed codominant gene expression except for EST-3, which was expressed in a dominant fashion due to the presence of a null allele. Monomeric quaternary structure was observed for ACO-1, ACO-2, EST-6, LAP-1, and SKDH. Dimeric quaternary structure was observed for AAT-1, AAT-2, FDH, PGD-2, and TPI-1. The isozyme loci Aat-2 and Skdh were linked with a map distance of 28 cM.
