- Key message
- Results indicate that TRAB1 is a true trans-acting factor involved in ABA-regulated transcription and reveal a molecular mechanism for the VP1-dependent, ABA-inducible transcription that controls maturation and dormancy in plant embryos
- The rice basic domain/Leu zipper factor TRAB1 binds to abscisic acid (ABA) response elements and mediates ABA signals to activate transcription
- We had shown previously that a chimeric promoter containing GAL4 binding sites became ABA inducible when a GAL4 binding domain-TRAB1 fusion protein was present
- This expression system allowed us to assay the ABA response function of TRAB1
- Our results suggest that the terminal or nearly terminal event of the primary ABA signal transduction pathway is the phosphorylation in the nucleus of preexisting TRAB1
