Abstract
Aluminum(Al) ion inhibits root growth and main constraint to crop growth in acid soils. Al tolerance in wheat and rye has been attributed to their ability to exude organic acids from roots to chelate and detoxify Al. We have recentry isolated wheat ALMT1 gene which encodes Al-activated malate transporter and is Al tolerant gene in wheat. In this study, we detected ALMT1 homologue in rye. Time-dependent enhancement of the ALMT1 homologue expression was correlated with the enhanced efflux of citrate and malate during Al treatment. The structure and functions of ALMT1 homologue(s) will be discussed.
