MATE — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.1HG0070210, designated HvMATE (also HvFRDL2), encodes a member of the MATE family, specifically a DinF-like protein with citrate transmembrane transporter activity, xenobiotic transmembrane transporter activity, antiporter activity, and transmembrane transporter activity. The protein localises to the plasma membrane, membrane, and root hairs, and is associated with citrate secretion and transport. HvMATE is associated with responses to aluminium, water deficit, and thirst, as well as with secondary and lipid metabolism. The gene has been linked to leaf chlorosis, manganese concentration, and aluminium response traits. Studies of related MATE family members in rice and sorghum connect the family to aluminium tolerance, root elongation, and root morphology. Additionally, sequence similarity to related genes in other species links the HvMATE family to agronomically important traits including grain yield, grain weight, grain size, seed size, plant height, and drought tolerance.
