Gene Details:

• Gene ID: HORVU.MOREX.r3.2HG0167320
• Gene Symbol: HvALMT1
• Gene Name: Aluminum-Activated Malate Transporter 1
• Genome: MorexV3_pseudomolecules_assembly
• Species: Hordeum vulgare

Functional Descriptions:

• HvALMT1 from barley is involved in the transport of organic anions.
• HvALMT1 is located on chromosome 2H which has not been associated with Al3+ resistance in barley. The relatively low levels of HvALMT1 expression detected in root and shoot tissues were independent of external aluminium or phosphorus supply.
• GFP fused to the C-terminus of the full HvALMT1 protein localized to the plasma membrane and motile vesicles within the cytoplasm.
• Both malate uptake and efflux were confirmed in oocyte assays using [14C]malate as a radiotracer. It is suggested that HvALMT1 functions as an anion channel to facilitate organic anion transport in stomatal function and expanding cells.
