TaOPR1 increases the ABA sensitivity of Arabidopsis. A, Delayed germination in the presence of ABA treatment. AtOE1 and AtOE2, Transgenic lines heterologously expressing TaOPR1; VC, transgenic line carrying an empty pSTART vector. B, TaOPR1 suppresses the growth of seedlings exposed to ABA for 10 d. C, Root lengths of seedlings shown in B. Data are presented as means ± sd, and columns marked with asterisks indicate significant differences from the VC line under the control or in each treatment using Student’s t test analysis (P < 0.05).
