Gene co-expression network and hub gene expression analysis. Gene co-expression network of the positively correlated turquoise (a) and green (b) modules and of the negatively correlated blue module (c). The size of the circle represents the number of linked genes (i.e., a bigger circle has more linked genes); the circle color represents the gene connectivity, and orange and blue represent the strongest and weakest connectivity, respectively; the lines between circles indicate correlations between genes. (d–g) Gene expression levels from qRT-PCR for the four hub genes LOC107422279 (d), LOC107432609 (e), LOC107415595 (f) and LOC107420503 (g). The vertical bars show the standard error and a significance level of 0.05 was used for different letters above bars
