AWD could induce the formation of iron plaque on root surface of rice seedlings significantly. However, differentially expressed genes (DEG) of rice roots remains unknown in the process of AWD induced formation of iron plaque. 【Method 】In this study, DEG of rice roots were investigated in response to waterlogging (CK), AWD, CK+Fe, AWD+Fe treatments in sand-culture experiments. 【Results 】Compared with CK, AWD induced up-regulated expression of 506 DEG and down-regulated expression of 687 DEG. Compared with CK+Fe, AWD+Fe induced u
