Figure 3. Analysis by qRT-PCR of the expression of three CycD3 genes of tomato in the hypocotyl of cv. Rutgers and 7B-1 seedlings grown for 2 days in the D (0.

h BL) and transferred for 24 h in continuous BL (10 µmol.m ⁻² .s ⁻¹ ; 24 h BL). Results represent averages ± SE of three independent biological repeat. The EF1α gene was taken as housekeeping gene. The relative quantification was made against the expression of SlCYCD3;1 from the sample ‘0 h BL cv. Rutgers’. Statistics were done separately for each gene; a: significantly different from the D condition; b: significantly different from cv. Rutgers in the same light condition (two-way ANOVA, Bonferroni post-hoc test, p<0.05).
