Overexpression of JUB1 Confers Tolerance to H2O2.
(A) Two-week-old RD29A:JUB1 and EV seedlings grown on solid MS medium were transferred to liquid medium containing 10 mM H2O2 and incubated for 24 h. RD29A:JUB1 seedlings remained green, whereas EV lines bleached in the presence of H2O2.
(B)
JUB1-IOE lines treated with 15 μM EST survived better than plants treated with 0.15% ethanol (mock treatment) after transferring 3-week-old plants to fresh medium containing 10 mM H2O2 for 6 d.
