MST4 — Triticum aestivum

Summary

TRAESCS1D02G343200 (symbol MST4, preferred name TaSTP6) on bread wheat chromosome 1D encodes a monosaccharide transmembrane transporter with symporter activity, belonging to the MFS_STP/MST-like plant family and localised to the membrane and plasmalemma. The gene is associated with virus-induced post-transcriptional gene silencing. It has been linked to anther extrusion and wheat stripe rust disease response. Studies of related genes in other species connect the family to spikelet number, grain number, plant height, anthesis time, heterosis, and drought tolerance, though these associations are not established for this wheat gene.
