Fig. 7.

Relative expression patterns of BOACO1 and ethylene receptor genes (a) and ethylene biosynthesis genes (BOACS1, BOACS3, BOACS4, BOACS5, BOACS7, BOACS9, and BOACS11) (b, c) in secondary dormant Brassica oleracea seeds incubated in water at 21 °C. Transcript levels for each gene were estimated by qRT-PCR. The fold changes indicate the expression patterns of analyzed genes relative to their transcript levels in dry seeds (0 h of incubation) with assumed value of 1. Statistical analyses: two-way ANOVA with post hoc Tukey’s (HSD) test with confidence interval 0.05, significance between groups indicated as * for P ≤ 0.05 and ** for P ≤ 0.01
