The pSPL9:rSPL9 suppressed the delayed vegetative phase change of det2-1 mutant. (A) The growth phenotype of 5-week-old wild type, det2-1, pSPL9:rSPL9 and pSPL9:rSPL9/det2-1 plants. (B) The rosette leaf numbers of wild type, det2-1, pSPL9:rSPL9 and pSPL9:rSPL9/det2-1 after flowering. Error bars represent standard deviation (n = 10). Different letters above the bars indicated statistically significant differences between the samples (ANOVA analysis followed by Uncorrected Fisher’s LSD multiple comparisons test, p < 0.05). (C) The shape phenotypes of full expanded rosette leaves of wild type, det2-1, pSPL9:rSPL9 and pSPL9:rSPL9/det2-1. (D) The 3rd leaf length of wild type, det2-1, pSPL9:rSPL9 and pSPL9:rSPL9/det2-1 after initiation different days. The leaf lengths were measure from at least 30 plants. Error bars represent standard deviation. (E) The ratio of leaf width to leaf length of full expanded rosette leaves of wild type and indicated plants. The leaf width and leaf length were measure from at least 30 plants. Error bars represent standard deviation. (F) The base angle of full expanded rosette leaves of wild type and indicated plants. The leaf base angle were measure from at least 30 plants. Error bars represent standard deviation.
