Hypothetical model for regulation of seed dormancy by OsWRKY29. (A) In the absence of ABA, OsWRKY29 binds to the OsVP1 and OsABF1 promoters to repress their expression, thus weakening the ABA response and permitting seed germination. (B) The presence of ABA represses OsWRKY29 expression to relieve its repression on the expression of OsVP1 and OsABF1, thus resulting in the high expression of OsVP1 and OsABF1 to strengthen ABA response and promote seed dormancy.
