Statistical analysis
Seasonal flowering expression of genes was analysed by two-way ANOVA
using the prism software with the following predictors: time-point,
site, and their interaction. The detailed statistical analysis is
summarised in Table S5. Gene expression data between leaves from plants
that subsequently flowered and those from plants that remained
vegetative at different altitudes during the inductive summer period
were analysed using a two-way student’s t-test.
