To explore variation patterns of uptake, translocation, and accumulation processes responding to organophosphate esters (OPEs) among Poaceae plants, hydroponic and computer simulation experiments were executed. Plant growth, OPEs' concentration, and bioinformation and transcript of lipid transporters in the three terrestrial barley, wheat, and maize and aquatic rice seedlings were studied after exposure to seven OPE congeners. Four types of plants could accumulate seven OPE congeners. OPEs could promote rice growth by upregulating IAA27 hormone gene. However, maize growth was inhibited due to upregulating IAA17 hormone gene. In general, OPEs with log K
