Gene Details:

• Gene ID: TraesCS4D02G283600
• Gene Symbol: ALMT1-2
• Gene Name: aluminum-activated malate transporter
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Here, we report on the cloning of a wheat gene, ALMT1,that co-segregates with Al tolerance in F2 and F3 populations derived from crosses between near-isogenic wheat lines that differ in Al tolerance.
• The ALMT1 gene encodes a membrane protein, which is constitutively expressed in the root apices of the Al-tolerant line at greater levels than in the near-isogenic but Al-sensitive line.
• ALMT1 increased the tolerance of tobacco cells to Al treatment. These findings demonstrate that ALMT1 encodes an Al-activated malate transporter that is capable of conferring Al tolerance to plant cells.
• Taken together, these results indicate that both ALMT1-1 and ALMT1-2 genes encode Al-activated transporters that facilitate malate efflux from tobacco cells, and that the expression of both ALMT1 genes increases Al tolerance by decreasing the accumulation of Al in cells.
