Ethylene breaks seed and bud dormancy
WebIt has long been known that the relative levels of plant hormones control seed dormancy and germination. Gibberellins (GAs) break seed dormancy and promote germination (1, 2), and several other hormones, including brassinosteroids, ethylene, and cytokinin, have also been shown to promote seed germination (3, 4).However, abscisic acid (ABA) is the only … WebEthylene signaling appears critical for grape bud dormancy release. We therefore focused on identification and characterization of potential downstream targets and events, assuming that they participate in the regulation of dormancy release. Because ethylene responding factors (ERF) are natural cand …
