Abstract

DELLA proteins act as negative regulators in gibberellin (GA) signal transduction. GA-induced DELLA degradation is a central regulatory system in GA signaling pathway. Intensive studies have revealed the degradation mechanism of DELLA and the functions of DELLA as a transcriptional regulator. Meanwhile, recent studies suggest the existence of a DELLA-independent GA signaling pathway. In this review, we summarized the DELLA-independent GA signaling pathway together with the well-analyzed DELLA-dependent pathway.

Keywords: DELLA; Gibberellin; calcium.
