Characterization of Genes for Beef Marbling Based on Applying Gene Coexpression Network
Figure 3
Analysis results of gene expression data by regression model and PCA. (a) Biplot of the first two principal components. The symbols of L (left) and H (right) represent low- and high-marbled samples in the plot, respectively. (b) Regression analysis between expression level (-axis) and intramuscular fat content (%, -axis) for each sample. CEBPa and PPARG were used as indicators of marbling (intramuscular fat).
