Fig. 2.

Up-regulated genes in KEGG metabolism category in the comparison of ‘Kiyomi’ to ‘Shiranui’ (a) and in the comparison of ‘Shiranui’ to ‘Kiyomi’ (b). The orange-to-blue scale represents a decreasing log₂-fold change of gene expression. K1/S1: the comparison of ‘Kiyomi’ to ‘Shiranui’ at the first stage; K2/S2: the comparison of ‘Kiyomi’ to ‘Shiranui’ at the second stage; S1/K1: the comparison of ‘Shiranui’ to ‘Kiyomi’ at the first stage; S2/K2: the comparison of ‘Shiranui’ to ‘Kiyomi’ at the second stage
