DIM — Oryza sativa Indica Group

Summary

BGIOSGA031980 (OiDIM, also known as BRD2, DWF1, and CBB1) on chromosome 10 of indica rice encodes a diminuto-like protein with D24-sterol reductase activity (EC 1.3.1.72) and FAD binding. The gene is associated with brassinosteroid anabolism, steroid metabolism, lignin metabolism, chlorophyll anabolism, homogalacturonan biosynthetic process, secondary cell wall biogenesis, polar cell growth, and response to light stimulus. It has been connected to grain size, grain shape, and grain quality in rice, as well as plant height, flowering time, chlorophyll content, grain yield, seed growth and development, leaf senescence, jasmonic acid content, abscisic acid sensitivity, and stomatal closure time. The encoded protein localizes to the Golgi complex, trans-Golgi network, endosome, vacuole, plastid, membrane, and cytosol. Studies of related genes in other species link the family to dwarfism, cell elongation, pectin biosynthesis, and herbivory resistance.
