Abstract:
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.

Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...
