WebMay 12, 2014 · Gibberellin (GA)-dependent degradation of DELLA protein, a key negative regulator, is essential for GA action. However, it is unclear how DELLA regulates downstream gene expression. Although possessing strong transactivation activity, DELLA lacks a DNA-binding domain. WebThe plant hormone gibberellin (GA) controls major aspects of plant growth such as germination, elongation growth, flower development, and flowering time. In recent years, a number of studies have revealed less apparent … The GA signal is perceived by the GA receptor GID1 (for GA INSENSITIVE DWARF1), which is a soluble protein that is localized to both cytoplasm and nucleus. DELLA proteins are nuclear transcriptional regulators, which repress GA signaling and restrict plant growth presumably by causing transcriptional … See more The biochemical pathway of GA biosynthesis and catabolism in plants is well defined, and genes encoding most enzymes in this pathway have been identified … See more DELLA proteins belong to the GRAS family of plant-specific nuclear proteins, which do not contain any canonical DNA-binding domain and therefore, are likely to regulate expression … See more Recent genetic, biochemical, and structural studies have elucidated the molecular mechanism of GA perception and initial steps in GA signaling in plants (Fig. 1; Ueguchi-Tanaka et al., 2007; Sun, 2008). The GA signal … See more To understand how the GA-GID1-DELLA module regulates plant growth and development, it will be necessary to monitor the sites and timing of the actions of this module.
