Comparative transcriptomic analysis of ovaries from high and low egg-laying Lingyun black-bone chickens.

ABSTRACT: Egg-laying rate is mainly determined by ovarian function and regulated by the hypothalamic-pituitary-gonadal axis; however, the mechanism by which the ovary regulates the egg-laying rate is still poorly understood. The purpose of this study was to compare the differences in the transcriptomes of the ovary of Lingyun black-bone chickens with relatively high and low egg-laying rates and screen candidate genes related to the egg-laying rate. RNA-sequencing (RNA-Seq) was conducted to explore the chicken transcriptome from the ovarian tissue of six Lingyun black-bone chickens with high (group G, n = 3) and low (group D, n = 3) egg-laying rates. The results showed that 235 differentially expressed genes (DEGs) were identified between the chickens with high and low egg-laying rates; among them, 2
