GID1 — Beta vulgaris subsp. vulgaris

Summary

BVRB_014220 (GID1) in sugar beet (Beta vulgaris subsp. vulgaris) encodes a protein with carboxylesterase activity, gibberellin binding, and ent-kaurene oxidase activity, belonging to the alpha/beta hydrolase and carboxylest/gibberellin receptor families. It is associated with gibberellin-mediated signalling, hormone metabolism, and responses to strigolactone and light. The gene is linked to traits including gibberellic acid sensitivity, plant male sterility, seed set percent, leaf area, shoot system elongation, and whole plant size. It has been connected to phenotypes such as dwarfism responsive to gibberellin, taproot growth, seed germination, root development, and water use efficiency. Localisation evidence places the product in the cytosol, chloroplast outer membrane, mitochondria, and amyloplast. Related genes in other species are linked to primary root growth, ent-kaurene oxidation, and IAA biosynthesis.
