Organophosphate esters uptake, translocation and accumulation in rice (Oryza sativa L.): impacts of lipid transporters and chemical properties

Abstract

To explore key factors involved in the uptake, translocation and accumulation of organophosphate esters (OPEs), computer simulation analysis and hydroponic experiments were executed. Lipid transporters with stocky-like active (SAC) cavities usually showed stronger binding affinities with the OPEs, especially when the SAC cavities belong to the Fish Trap model according to molecular docking. In our hydroponic trial, the binding affinity and gene expression of the lipid transporters and log Kow of the OPEs could be charged to the uptake, translocation and accumulation of the OPEs; however, these three factors played various important roles in roots and shoots. In detail, the effect of gene expression and binding affinity were stronger than log Kow in roots uptake and accumulation, but the result was the opposite in the shoots translocation. Transporters OsTIL and OsLTPL1 among all investigated transporters could play key roles in transporter-mediated OPE uptake, translocation and accumulation in the roots and shoots. OsMLP could be involved in the bidirected vertical translocation of the OPEs. OsLTP2 and OsLTP4 mainly acted as transporters of the OPEs in roots.
