Fig 3.

Relative expression levels of target genes in M. persicae after starvation normalized to Actin (A) and 18S (B) alone and in combination (C). Values are shown as the mean ± SEM. Bars with different letters are significantly different from each other (P < 0.05). Lowercase letters indicate the comparison among different starvation time for one target gene normalized with the same housekeeping gene. Uppercase letters represent the comparison among different normalized genes for one target gene under the same starvation time.
