TSN — Triticum turgidum subsp. durum

Summary

TRITD4BV1G008910 (symbol TSN, also known as TtTSN, TtTUDOR1, TtTSN2, TtTSN1, TSN2, TSN1, TtTUDOR2, TUDOR2, TUDOR1) on durum wheat chromosome 4B encodes an uncharacterized protein containing Tudor and staphylococcal nuclease domains, with annotated nuclease and hydrolase activities and RNA/mRNA binding. The gene is associated with positive regulation of gibberellin biosynthetic process, protein secretion, mRNA breakdown, cellular response to heat, response to cadmium, RNA-dependent gene silencing, mRNA processing, and salinity response. It localizes to the RNAi effector complex, perinuclear region, P body, nuclear envelope, stress granule, cell wall, ER, plasmodesma, plastid, and cytosol. TSN is linked to spot blotch and septoria nodorum blotch susceptibility in durum wheat, and to tan spot severity, grain number, salt stress tolerance, heat stress response, grain weight, and delayed GA3-rescuable germination. Related genes in other species are linked to seed germination and gibberellin biosynthesis.
