It also affects plant response to biotic and abiotic stresses. GA metabolism and signaling in tomato ( Solanum lycopersicum) have been studied in the last three decades and major components of the pathways …
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. In the … See more WebMay 5, 2013 · Gibberellin (GA), one of the important phytohormones in higher plants, has been well-known to mediate many developmental processes, such as seed germination, vegetative growth, flowering induction and fruit development [ 1 – 4 ]. DELLA proteins are key repressors in GA signaling.
WebDOI: 10.1104/pp.104.039578 Abstract RGA (repressor of ga1-3) and GAI (gibberellin insensitive) are negative regulators of plant hormone gibberellin (GA) signaling in … WebAug 18, 2024 · Gibberellins (GAs) are phytohormones essential for various growth processes in plants, such as seed germination, stem elongation, and the regulation of flower, fruit, and seed development. GA signaling is mediated by three components, a nuclear receptor GA-INSENSITIVE DWARF1 (GID1), a DELLA protein, which …
WebHere we show that gibberellin (GA) signalling mediated by DELLA proteins inhibits rhizobial infections and controls the NF induction of the infection marker ENOD11 in Medicago truncatula. Ectopic expression of a constitutively active DELLA protein in the epidermis is sufficient to promote ENOD11 expression in the absence of symbiotic signals.
