IAA Biosynthesis in Auxin and Cytokinin Signal Transduction Mutants.

De novo IAA biosynthesis rate (A) and IAA concentration (B) were analyzed in root tips of auxin and cytokinin signal transduction mutants after treatment of 6 DAG seedling roots for 24 h with liquid medium containing 30% 2H2O with or without 5 μM t-Z. Data are mean ± sd of three independent experiments (n = 3). P values (+ t-Z versus – t-Z) were determined by two-tailed Student’s t test assuming equal variances (* P < 0.05, ** P < 0.01, and *** P < 0.001).
