Overexpression of PtrMATE1 in transgenic AtMATE knockout mutant (ATMATE-KO) and wild-type Arabidopsis confers Al tolerance. (A) Wild-type and transgenic Arabidopsis in MS medium containing 20 μM Al3+ for 10 d. PtrMATE1-OX:overexpression of PtrMATE1 in wild-type Arabidopsis, PtrMATE1-R:overexpression of PtrMATE1 in AtMATE knockout mutant. (B) root growth of these transgenic plants with/without Al treated.Student’s t-test: *P < 0.05, **P < 0.01, ***P < 0.001.
