The antagonizing effect of BR and ABA on seed germination. (A) Germination rates of BR-related mutants under ABA condition. (B) Nine-day old seedlings on 1/2 MS medium containing 0, 250 and 750 nM ABA. (C) Arrangements for genotypes in B and E. (D) Germination rates of BR biosynthetic and signaling mutants under NaCl condition. (E) Nine-day old seedlings on 1/2 MS medium containing 0, 75 and 175 mM NaCl. (F) Arrangements for genotypes in H. (G) The inhibitory effect of ABA on seed germination can be rescued by applied BL. (H) Nine-day old seedlings on 1/2 MS medium containing 500 nM ABA with 0, 1, or 100 nM BL. Germination rates were recorded at 5 days after plates were transferred to growth room. The experiments were repeated 3 times, and data are the average value (n ≈ 50) for each independent experiment. The error bars represent SE.
