Abstract excerpt
In maize, two paralogous genes, Sh1 and Sus1, encode two biochemically similar isozymes of sucrose synthase, SS1 and SS2, respectively. Previous studies have attributed the mild starch deficiency of the shrunken1 (sh1) endosperm to the loss of the SS1 isozyme in the mutant. Here we describe the f...
