Abstract
The molecular mechanisms which regulate the
developmental processes of ovary and result in increased reproductive efficiency
of beef cattle need further investigations for optimum beef production. The
study was designed to screen the signaling pathways and to investigate the genes
related to development of ovarian tissues of Xiangxi cattle at different age (6,
18 and 30 months) by transcriptome sequencing and bioinformatics analysis.
Illumina II high-throughput sequencing technology was used to seq transcriptomes
of nine Xiangxi cattles ovarian tissues at different ages. The total number of
ovarian genes assembled were compared with reference genome sequences,
differentially expressed gene analysis, KEGG and GO enrichment analysis and
finally the candidate genes screening were performed. The results showed that
about 68.51 Gb clean data was obtained and clean data of each sample reached to
the 6.10 Gb. A total of 26243 expressed genes were screened, of which 4866 genes
were new and have not been annotated in any database. A total of 594
differentially expressed genes were annotated between 6 and 30-months groups.
Similarly, a total of 141 differentially expressed genes were annotated between
18and 30-mths groups. Among these, the members of G-protein coupled receptors
family like follicle-stimulating hormone receptor (FSHR) and Insulin-like 3
peptides (INSL3) participate in signaling pathways. These results suggest that
FSHR and INSL3 may be related to the reproductive development and reproductive
performance of ovarian tissues in Xiangxi cattle and play an important role.
