LTN1 — Triticum turgidum subsp. durum

Summary

TRITD1BV1G209270 (symbol LTN1, also known as TtUBC24, TtPHO2, UBC24, PHO2) on durum wheat chromosome 1B encodes a ubiquitin-conjugating enzyme E2 24 with ubiquitin-protein transferase activity and inositol hexakisphosphate binding. It is associated with phosphate transmembrane transporter activity, intracellular phosphate homeostasis, regulation of phosphate membrane transport, and cellular response to phosphate starvation. The gene is linked to seed development, protein polyubiquitination, and ubiquitin-dependent proteolysis. Traits connected to LTN1 include shoot phosphorus content, phosphorus uptake, leaf necrosis, stem rust and stripe rust responses, low temperature stress response, abscisic acid sensitivity, and reproductive period. Phenotypic associations involve root architecture, adventitious root development, plant growth, freezing tolerance, salt stress response, flowering time, leaf senescence, and phosphate accumulation and translocation. The encoded protein localises to the nucleus, endoplasmic reticulum, Golgi, mitochondria, and plasma membrane.
