Morphologies of GhCEN-Dt over-expression plants. a Jimian 14 (wild-type) with an indeterminate phenotype. Scale bars, 15 cm. b Jimian 14 overexpressing GbCEN-Dt from Hai 170 with normal flowering time. Scale bars, 15 cm. c Jimian 14 overexpressing GhCEN-Dt from CCRI 35 with delayed flowering time. Scale bars, 15 cm. d Relative GhCEN transcript levels in transgenic lines and WT. **P < 0.01, error bars are SD of three biological replicates. e Position (node) of the first fruiting branch formed in WT, 35S::cen and 35S::CEN cottons. **P < 0.01, error bars are SD of three biological replicates; n.s., not significant. f and g Branching phenotypes of the 10th node in 35S::cen (f) and 35S::CEN (g) over-expressed cotton. Scale bars, 60 cm
