(A) The distribution of gene expression was shown using a box plot: the abscissa is the sample name, the ordinate is log10 (FPKM), and the box plot of each region corresponds to five statistics (top to bottom are the maximum, upper quartile, middle value, lower quartile, and minimum). (B) Distribution of FPKM density. The expression density of each sample conforms to the normal distribution, and the expression trends of biological replicate samples are consistent. The abscissa is log10 (FPKM) and the ordinate is the density of the gene.
