Abstract: The objective of this research was to clone the histone deacetylases 1 (HDAC1) gene of yak and identify its expression patterns in various tissues and oocytes during meiosis process, respectively, which would provide theoretical basis for studying the role mechanism of HDAC1 in reproductive development of yak. The samples of yak heart, liver, spleen, lung, kidney, small intestine, brain, muscle, ovary and uterus were collected after slaughtering. Total RNAs in different samples were extracted. The coding sequence of HDAC1 gene was cloned by RT-PCR. Its structure and function were analyzed by bioinformatics softwares. The mRNA expression of HDAC1 in different tissues and oocyte during meiosis process was detected by quantitative real-time PCR (qRT-PCR). The results showed that the open reading frame HDAC1 was 1 302 bp, encoding 433 amino acids. It had high homology with cattle, sheep and goat. HDAC1 gene of yak was widely expressed in various tissues, the expression level of which was significantly higher in spleen, kidney and small intestine(P<0.01). The expression level of HDAC1 in MI and MⅡ stages was significantly higher than that in GV stage in oocytes of yak(P<0.01). This study suggested that HDAC1 was involved in meiosis process of oocytes in yak, which provided basic data for studying the role of HDAC1 in reproductive development of yak under the harsh natural environment of the plateau.
