Hierarchical cluster analysis of the 1805 differentially expressed genes in the SPL. Expression was increased or decreased at a significance level of p < 0.05. Gene tree (Pearson correlation: left tree) shows correlated groups of genes and their expression patterns across all individual samples (bottom axis). The 3 groups highlight the separation of the gene clusters. MGP analysis was performed for each cluster and the top 1 ~ 3 GO categories (BP, MF, or/and CC) were listed. Colors show the range of expression from blue (decreased expression) to yellow (increased expression).
