- DEFECTIVE IN ANTHER DEHISCENCE 1 (DAD1), a phospholipase A1, utilizes galactolipids (18:3) to generate α-linolenic acid (ALA) in the initial step of jasmonic acid (JA) biosynthesis in . In this study, we isolated the gene, an ortholog of in , and found that it is mainly expressed in the stems, roots, and male flowers of . -RNAi transgenic plants with low endogenous jasmonate levels in inflorescences exhibited more and larger flowers, as well as a few abortive female flowers, although anther and pollen development were normal. In addition, fruit number was increased and the seed size, weight, and oil contents were reduced in the transgenic plants. These results indicate that regulates the development of flowers and fruits through the JA biosynthesis pathway, but does not alter androecium development in . These findings strengthen our understanding of the roles of JA and in the regulation of floral development in woody perennial plants.
