Fig. 4: Analysis of fatty acid (FA) biosynthesis genes in the Chinese tallow tree (CTT) genome.

a The development of CTT seeds. S1 to S4 indicate 1, 3, 5, and 16 weeks after pollination (WAP), respectively. The upper panels indicate transverse cross sections of CTT seeds in different developmental stages, while the bottom panels indicate the longitudinal sections of CTT seeds. b Numbers of genes involved in fatty acid biosynthesis for five plants in the Euphorbiaceae family. The monoploid genome sequence was used to perform this analysis. c Gene expression patterns of FA biosynthesis genes in leaves and S1 to S4 developmental stages. The five boxes with different colors indicate these five samples. Scaled reads per kilobase per million mapped reads (RPKM) values were used for the heat plot.
