Abstract
Methods are described herein for producing male-sterile plants by underexpressing the allene oxide synthase (CYP74A) gene. Fertility is restored in the plants by treatment with jasmonic acid. Hybrid seed production is simplified and improved by this invention. The present invention also includes plants transformed with an allene oxide synthase coding sequence.
