Transcriptome analysis of lipid synthesis genes in developing seed and the caruncle. The expression levels of key classes of genes involved in fatty acid and TAG synthesis are listed in fragments per kilobase per million mapped reads (FPKM) with fold change of expression level of the caruncle vs. seed (log2). S4, seed stage 4; C4, the caruncle stage 4. The FPKM and fold change values are color coded with the scale shown in inlet.
