Expression profiles of the lipid-related genes in sesame seed. (a) Hierarchical clustering of the sesame seed samples based on the expression levels (RPKM) of 416 predicted lipid-related genes. (b) Differently expressed genes (DEGs) of 10 DPA seeds in the downstream part of the triacylglycerol (TAG) synthesis pathway. DEGs between the high and low lipid content accessions in this pathway are marked in red. Colored squares indicate the expression level (RPKM) of the 10 DEGs encoding phosphatidylcholine:diacylglycerol cholinephosphotransferase (PDCT), phospholipid: diacylglycerol acyltransferase (PDAT), oil-body proteins (steroleosin, caleosin and oleosin) and transcription factors (ABI3, ABI4 and WRI1) in the three accessions (from left to right): ZZM4728 (high oil content, 59% of seed), ZZM3495 (low oil content, 51% of seed), and ZZM2161 (low oil content, 48% of seed). The correlation (r) of expression patterns between transcription factors and genes was calculated using Pearson’s correlation coefficients (PCCs) based on all 12 transcriptomes. Dashed arrows indicate potential positive regulation.
