网页2018年5月20日 · Gibberellin is type of plant and fungal hormone. While its role in fungal development is not as clearly understood, it has been extensively studied in plants. Gibberellin is one of 5 major groups of plant hormones, the others being auxins, cytokinins, ethylene and abscisic acid.
Gibberellin - an overview | ScienceDirect Topics
网页Gibberellin (GA) is a plant hormone existing widely in nature, which promotes plant growth and cells division. Meanwhile, gibberellin modulates the regulation of anthocyanin biosynthesis. For instance, exogenous GA applications decreased anthocyanin content in tomato (Micro-Tom) hypocotyls (Carvalho et al., 2010).
Gibberellin | Definition, Function, & Uses | Britannica
网页gibberellin, any of a group of plant hormones that occur in seeds, young leaves, and roots. The name is derived from Gibberella fujikuroi, a hormone-producing fungus in the phylum Ascomycota that causes excessive growth and poor yield in rice plants. Evidence suggests that gibberellins stimulate the growth of main stems, especially when applied ...

网页2018年3月1日 · Gibberellins (GAs) are considered phytohormones and conform a large family of diterpenoids that possess the tetracyclic ent -gibberellane carbon skeletal structure arranged in either four or five ring systems where the variable fifth ring is a lactone.
Gibberellin Metabolism in Flowering Plants: An Update and …
网页2020年5月18日 · Recent advances in downstream GA biosynthesis (after GA 12 formation) suggest that species-specific gibberellin modifications were acquired during flowering plant evolution. Here, we summarize the current knowledge of GA metabolism in flowering plants and the physiological functions of GA deactivation, with a focus on GA 13 hydroxylation.
Plant Development and Crop Yield: The Role of Gibberellins
网页2022年10月9日 · The nuclear receptor GIBBERELLIN-INSENSITIVE DWARF1 (GID1) is responsible for the perception of GA. The GA–GID1 interaction enables the ubiquitination and degradation of DELLA proteins, which act as repressors of GA signaling.
