Viviparous-5 encodes phytoene desaturase, an enzyme essential for abscisic acid (ABA) accumulation and seed development in maize.

Molecular & general genetics : MGG - 1 Jan 1998

Hable W E, Oishi K K, Schumaker K S

Abstract excerpt

The role of synthesis in the regulation of abscisic acid accumulation was investigated in the developing maize seed. To do this, expression and regulation of the abscisic acid biosynthetic enzyme phytoene desaturase were examined. Comparison of the gene sequence encoding phytoene desaturase and its transcript in the wild-type and viviparous-5 mutant showed that the mutant gene contains multiple insertions and...
