Abstract excerpt
A new Zea mays viviparous seed mutant, viviparous15 (vp15), was isolated from the UniformMu transposon-tagging population. In addition to precocious germination, vp15 has an early seedling lethal phenotype. Biochemical analysis showed reduced activities of several enzymes that require molybdenum cofactor (MoCo) in vp15 mutant seedlings. Because MoCo is required for abscisic acid (ABA) biosynthesis, the viviparous...
