DIM — Solanum tuberosum

Summary

PGSC0003DMG400021142 (StDIM, also known as StDWF1 or StCBB1) on potato chromosome 2 encodes a diminuto-like protein with D24-sterol reductase activity (EC 1.3.1.72), an oxidoreductase acting on CH-CH groups with NAD or NADP as acceptor. The gene is associated with brassinosteroid, sterol, cholesterol, ergosterol, isoprenoid and lignin metabolism, as well as secondary cell wall biogenesis and mechanical stimulus response. It has been linked to traits including amylose and protein content, self-incompatibility, pollen fertility restoration, jasmonic acid content, stomatal closure time, leaf senescence, seed development, abscisic acid sensitivity, flowering time and salt tolerance. Associations with nitrogen accumulation, root elongation, leaf size, hypocotyl growth, cell proliferation, post-embryonic growth, UV-B stress response, male fertility and seed germination have also been reported. The protein localises to the Golgi, trans-Golgi network, endosome, vacuole, plastid, membrane and cytosol.
