arr1,11,12 mutant seedlings are insensitive to the inhibition of cytokinin and ABA on primary root growth. A, Representative examples of wild-type and arr1,11,12 seedlings on MS medium plates or plates with either 10 µm 6-benzyladenine (6-BA) or 10 µm ABA. Five-day-old seedlings grown on MS medium were transferred to MS plates or plates supplemented with either 6-BA or ABA. The photographs were taken 5 d after the transfer. Bars = 10 mm. B, Primary root lengths of wild-type and arr1,11,12 seedlings at 5 d after transfer to MS medium plates or plates with either 6-BA or ABA. The data represent mean values ± se (n > 15). Asterisks indicate that the primary root length of arr1,11,12 is significantly longer than that of the wild type on MS medium plates with either 6-BA or ABA (Student’s t test, P < 0.05). C, Schematic representation of the interactions between ABA and cytokinin signaling mediated by ARR1 and PYL1.
