DIM — Solanum tuberosum

Summary

StDIM (PGSC0003DMG400011801) on potato chromosome 2 encodes a Diminuto-like protein with D24-sterol reductase activity (EC 1.3.1.72) and FAD binding. The gene is associated with brassinosteroid, sterol, steroid, isoprenoid and chlorophyll anabolism, as well as lignin metabolism, secondary cell wall biogenesis, cell growth, the cell cycle, polar cell growth, mechanical stimulus response, virus-induced PTGS, and calcium ion detection. It has been linked to traits including pollen fertility restoration, flowering time, leaf senescence, seed growth and development, stomatal complex closure time, abscisic acid sensitivity, jasmonic acid content, and salt tolerance. Associated phenotypes include dwarfism, reduced cell elongation, altered root and hypocotyl growth, nitrogen accumulation, and UV-B stress response. The protein localises to the Golgi, trans-Golgi network, endosome, vacuole, plastid, plasma membrane and cytosol. Studies of related genes in other species connect the family to plant height, drought tolerance, fruit shape and size, and lignin and cellulose content.
