Heatmap of the 94 DEGs associated with hormonal pathways after TSA treatment. The heatmap of FPKM (fragments per kilobase of transcript per million reads mapped) of 94 DEGs associated with hormone signal transduction in three biological replicates of Mock and TSA treatment ovules. The DEGs were then divided into four groups (a–d) according to the expression profiles in ovules of mock and TSA treatments. a The genes significantly up-regulated in response to TSA treatment; b the genes that showed a weak difference with less FPKM values; c the genes that showed a weak difference with more FPKM values; d the genes significantly down-regulated in response to TSA treatment. Log10-transformed (FPKM + 1) expression values were used to create the heat map. The red and green colors represent the higher and lower relative abundance of each transcript in each sample, respectively
