LINKAGE, CHROMOSOMAL ASSOCIATION, AND EXPRESSION OF ADH-1 AND PGM-2 IN TOMATO

The linkage relationship and chromosomal association of two genes in tomato coding for the respiratory enzymes alcohol dehydrogenase and phosphoglucomutase are reported. Also included is a description of where in the life cycle of the plant these genes are expressed. The finding that in pollen and germinating seeds most if not all of the detected activity of these two enzymes apparently arises from these genes suggests that the two isozymes might function in the same respiratory pathway. © 1979 Plenum Publishing Corporation.
