Abstract

Arsenic contamination is a major problem in South Asia particularly in Bangladesh and West Bengal. It is important to investigate how the As is transported to rice plants. Arsenite transporter in rice and Arabidopsis has recently been reported. It is also reported in Arabidopsis that arsenate is taken by plants through phosphate transporters. Here we investigated possible roles of phosphate transporter in arsenate transport in rice. There are 13 putative rice phosphate transporters (OsPTs) in rice and their patterns of expression vary in terms of induction by phosphate conditions and tissue specificity. We found that a T-DNA insertion mutant for one of the transporter gene accumulate less As in plant body, suggesting involvement of the phosphate transporter(s) in arsenate transport in rice.
