Fig. 5

Volcano plot of DEGs and eggshell ultrastructure at the initiation (8.5 h PO) and growth (18.5 h PO) stages of eggshell calcification. A shows a mimetic diagram of sampling, the uterus and eggshell were removed to determine the transcriptome and ultrastructure, respectively. B and D at the initiation stage of eggshell calcification; C and E at the growth stage of eggshell calcification. SM, shell membrane; MK, mammillary knob; TT, total thickness; ET, effective layer thickness; MT, mammillary layer thickness; PO, post-oviposition; HBS, high eggshell breaking strength group; LBS, low eggshell breaking strength group. Asterisk (*) denotes significant difference (P < 0.05) between the HBS and LBS
