GID1 — Sorghum bicolor

Summary

SORBI_3009G134600 (SbGID1) on chromosome 9 encodes a protein with a lipase domain, an alpha/beta hydrolase fold, and carboxylesterase activity, and is associated with gibberellin binding, gibberellin-mediated signalling and metabolism. The gene is linked to a wide range of traits including stem length, whole plant size, leaf area, shoot system elongation rate, seed set percent, photoperiod-sensitive flowering time, plant male sterility, pre-harvest sprouting, and responses to light quality, blue light, UV light, temperature stress, and viral and powdery mildew diseases. It is associated with drought stress, stomatal conductance, abscisic acid biosynthesis, auxin homeostasis, and root gravitropism. Related genes in other species are linked to primary root growth, ent-kaurene oxidation, and IAA biosynthesis, and to submergence tolerance and brown planthopper resistance.
