GID1 — Oryza sativa Japonica

Summary

Rice GID1 (Os05g0407500) encodes a protein with a gibberellin receptor domain, carboxylesterase activity, and an alpha/beta hydrolase fold, and is associated with gibberellin binding and gibberellin-mediated signalling. The gene is linked to dwarfism, submergence tolerance, resistance to brown planthopper, and responses to abscisic acid and ethylene. It has been connected to traits including stem length, leaf area, spikelet fertility, seed set, photosynthetic ability, photoperiod-sensitive flowering time, and plant male sterility. GID1 is also associated with blue light sensitivity, UV light sensitivity, temperature stress response, and viral disease response. Studies of related genes in other species link the family to dwarf phenotypes, reduced stem elongation, elevated gibberellin levels, delayed flowering, and reduced seed number.
