Abstract:
:Environmental contamination of arsenic (As) and its accumulation in rice (Oryza sativa L.) is of serious human health concern. In planta speciation of As is an important tool to understand As metabolism in plants. In the present study, we investigated root to shoot As translocation and speciation in rice exposed to inorganic and methylated As. Arsenate (AsV) and methylarsonate (MAV) were efficiently reduced to arsenite (AsIII) and MAIII, respectively in rice root and shoot but no trivalent form of dimethylarsinate (DMAV) was detected. Further, up to 48 and 83% of root As in AsV and MAV exposed plants, respectively were complexed with various thiols showing up to 20 and 16 As species, respectively. Several mixed As- and MA-complexes with hydroxymethyl-phytochelatin, DesGly-phytochelatin, hydroxymethyl-GSH and cysteine were identified in rice. Despite high complexation in roots, more As was translocated to shoots in MAV exposed plants than AsV, with shoot/root As transfer factor being in order DMAV > MAV > AsV. Moreover, in shoots 78% MAIII and 71% AsIII were present as weakly bound species which is alarming, as MAIII has been found to be more cytotoxic than AsIII for human and it could also be an important factor inducing straighthead (spikelet sterility disorder) in rice.
