Shoot phenotype in ntccd8 mutant and wild-type plants. (A) Photograph of 40-day-old wild-type and ntccd8 mutant plants. The scale bars equal to 20 cm. (B) Detail of primary branches in 40-day-old ntccd8 mutant plants. Main stem length (C), leaf number (D) and internode length of the main stem (E) were determined at 20 d, 40 d and 60 d after transplanting, respectively. (F) Total number shoot branches in ntccd8 mutant plants at 20 d, 40 d, 50 d, 60 d and 90 d after transplanting. Data are represented as the means ± SD (n = 10 for wild-type plants versus n = 12 for mutant plants). The asterisks indicate statistically significant differences compared to wild-type plants (* p < 0.05, ** p < 0.01 and *** p < 0.001; Student’s t-test).
