| Research Abstract |
We identified several transporter genes involved in accumulation and detoxification of toxic metals including Cd, As and Al. TcHMA3 isolated from a Cd hyperaccumulator is required for tolerating high Cd and OsHMA3 from rice is involved in Cd accumulation in grain. We also found that Lsi1, a silicon influx transporter, is able to transport methylated arsenic(DMA and MMA). Furthermore, we have identified several novel transporter genes involved in Al tolerance in rice, Arabidopsis and buckwheat.
