Flowering plants proliferate through sexual reproduction and seed production. Seed germination and subsequent post-germinative growth are strictly regulated and require the precise coordination of multiple environmental and internal cues, including phytohormones. Abscisic acid (ABA) represses seed germination and post-germinative growth in Arabidopsis thaliana. Auxin and jasmonic acid (JA) stimulate ABA function; however, the possible synergistic effects of auxin and JA on ABA signaling and the underlying molecular mechanisms remain elusive.
