Ovarian Development and Vitellogenin Gene Expression under Heat Stress in Silkworm, Bombyx mori

Figure 3

Vitellogenin mRNA expressions in spinning larvae upon heat shock. (a) Fat body. (b) Ovary. The upper panel showed expression of vitellogenin and rp49 as revealed by semiquantitative RT-PCR. The lower panel showed relative expression level of vitellogenin. The transcript level of the vitellogenin gene was calculated relative to rp49 expression for each sample. Each histogram bar represents the mean relative expression of vitellogenin (–7) and the error bar represents standard error of the mean (SEM). The asterisks show the data which are significantly different from control sample (unpaired -test; , , and ). The abbreviations used are as mentioned for Figure 1.
