cpl1 alleles have increased JA sensitivity. (a–c) Sensitivity of wild-type (WT) and cpl1 seedlings to JA was determined by MeJA inhibition of root growth on (a) control media or (b) media containing MeJA (25 uM). (c) Root elongation of each line when grown on MeJA was calculated as a percentage relative to their root length on the control. Shown is the average ± SE of 5 biological replicates consisting of pools of 10 seedlings. Asterisks indicate values that are significantly different (**P < 0.01, Student’s t-test) from WT. Similar results were obtained in an independent experiment.
