Knockout or overexpression of OsHAC1;1 or OsHAC1;2 affect arsenic accumulation in rice grain under aerobic soil conditions. A, As concentration in brown rice of OsHAC1;1 or OsHAC1;2 knockout mutants and wild-type (WT1, Zhonghua 11) plants. B, As concentration in brown rice of OsHAC1;1 or OsHAC1;2 overexpression lines and wild-type (WT3, Nipponbare) plants. Plants were grown in a soil amended with 20 mg As(V) kg−1 under aerobic conditions and rice grain were harvested at maturity. Data are means ± se (n = 4 biological replicates). Different letters above bars represent significant difference at P < 0.05.
