Temporal expression of flower-bud late genes. qRT-PCR analysis of flower-bud late genes at five time points from January to March (samples 1–5). Flower buds were collected from ‘Big Top’ cultivar. Genes from cluster A, B and non-clustered genes show violet, brown and green background, respectively. Expression levels are relative to actin. In each graph, the highest expression value was set to one, and the rest of the values were shown relative to this one. Data are means from two biological replicates, with error bars representing ± SD.
