GW5 — Oryza sativa Indica Group

Summary

BGIOSGA002928 (GW5, also known as OiIQD27) on chromosome 1 of indica rice encodes a calmodulin-binding protein containing an IQ motif and the DUF4005 domain. The gene is associated with grain size, grain shape, grain width, grain length, grain weight, and grain yield, as well as panicle weight, shoot dry weight, harvest index, and heterosis. It is linked to cell proliferation, the plasma membrane, spikelet, grain, domestication, stress tolerance, salt stress, and resistance. The encoded protein localises to the nucleus and is associated with genetic transfer and HDR processes. Studies of related genes in other species connect the IQD25 family to seed size, grain thickness, grain appearance, amylose content, protein content, drought sensitivity, and stigma exsertion.
