Variation in expression levels and pattern of hormone-related genes in SN and LGR. Genes related to hormone signaling that showed different expression pattern between SN and LGR and hence were present in separate clusters in Additional file 2- Figure S10, were extracted. Their expression levels (log₂FPKM) in SN and LGR were compared in a stage-wise manner. Number of genes, which had higher expression values (difference in log₂FPKM ≥ 0.5) in a stage in either SN or LGR, was counted. A–H Graphs represent the number of genes in different functional categories (biosynthesis, signal transduction, degradation, and response as mentioned below each graph) with higher expression in either SN or LGR for auxin, ABA, GA, ethylene, BR, CK, JA, and SA, respectively, in the five stages of seed development. This means in A there are 16 auxin responsive genes whose log₂FPKM value is at least 0.5 more in SN S1 stage than in LGR S1 stage, while reverse is true for 8 genes. Blue and orange lines indicate SN and LGR, respectively, as shown in the figure legends in each graph
