Expression patterns of SlTALE genes during chloroplast development and green shoulder formation in tomato fruit. (A) Expression patterns of SlTALE genes in the shoulder pericarp of WT and GS fruits. (B) Expression patterns of SlTALE genes in the shoulder and base pericarp of AC (Ailsa Craig) fruit. The RNA-seq data were normalized by FPKM (fragments per kilobase of exon per million fragments mapped) to construct the heatmap by TBtools software. The dpa indicates days post-anthesis, and Br+5 means 5 days after the breaker stage. W-s and W-b indicate the shoulder and base of WT fruit, respectively. G-s and G-b indicate the shoulder and base of the GS mutant fruit, respectively. The colored scale varies from blue to yellow, indicating relatively low or high expression, respectively.
