Comparison of phenotypes and expression differences in CCRI24 and pag1. a Phenotypes of WT (CCRI24) and pag1 plants at late development stages. b Mature leaves. c Phenotypes of stems in WT and pag1 plants. Green arrows indicate branch nodes. d Seedlings of WT and pag1 plants, showing short hypocotyl phenotype. e Adult fiber length of WT and pag1 plants. f-k the expression difference of GhGH3 genes in root (R), stem (S), leave (L), hypocotyl (H), 10 and 20 DPA fibers in WT and pag1 plants. The relative expression level of GhGH3 in WT organs/tissues was designated as 1, GhHis 3 was used as an internal control to normalize the expression data. Error bars show standard deviation calculated from three replications. Data points marked with asterisks (* P ≤ 0.05, ** P ≤ 0.01, and *** P ≤ 0.001) indicate statistically significant differences between control (GS) and other tissues
