The tomato MYB21 acts in ovules to mediate jasmonate-regulated fertility (Microarray)

ABSTRACT: The function of the plant hormone jasmonic acid (JA) in development of tomato flowers was analyzed with a mutant defective in JA perception (jasmonate-insensitive1-1, jai1-1). In contrast to Arabidopsis JA-insensitive plants that are male sterile, the tomato mutant jai1-1 exhibits major defects in female development resulting in female sterility. To identify putative JA-dependent regulatory components, transcriptomics was performed using isolated ovules of three different stages of flower development, from both wild type and jai1-1. Among the strongly down-regulated genes in jai1-1, one encoding a MYB transcription factor (SlMYB21) was found. Its orthologue in Arabidopsis has a crucial role in JA-regulated stamen development. SlMYB21 showed transcription factor activity in yeast, interacti
