HMA4 — Triticum turgidum subsp. durum

Summary

TRITD2AV1G241890 (symbol HMA4) on durum wheat chromosome 2A encodes a P-type Cu(+) transporter and Protein HEAVY METAL ATPASE 5. This gene is associated with P-type Divalent Copper Transporter Activity, P-type Monovalent Copper Transporter Activity, cadmium exporting ATPase activity, P-type Zinc Transporter Activity, and copper carrier activity. It is linked to copper ion transport, cellular copper ion homeostasis, detoxification of copper ion, and response to copper. The gene is associated with copper sensitivity, cell growth and development trait, flower development trait, leaf morphology trait, plant stress response trait, high temperature stress response, stomatal complex closure time, germination rate, root development trait, stomatal opening, leaf senescence trait, oxidative stress response, flowering time trait, plant growth and development trait, root morphology trait, and drought tolerance. It is also linked to viral resistance, copper accumulation, copper mobilization, ethylene signaling, and copper detoxification. Studies of related genes in other species connect the family to grain yield, grain zinc and iron content, panicle size, heading date, and chlorophyll content.
