Differentially expressed unigenes (DEGs) of gingers among sample comparisons (FI: potential flower bud of ginger under induced by photoperiod and light quality; LI: induction treatment of ginger leaf bud; LN: leaf bud of ginger under natural condition). A Correlation analysis of sample groups; the number in the grid represents the square of Pearson correlation coefficient (R²) and the higher R² represents the better correlation between samples. B Venn diagrams of DEGs between sample pairs
