Anlysis on the Intestinal Microbial Diversity in Gymnocypris namensis,A Typical Lake Fish on the Qinghai Xizang Plateau
The purpose of this paper was to analyze the community structure and diversity characteristics of the intestinal microorganisms in Gymnocypris namensis,and to investigate the possible roles of the intestinal microorganisms,so as to provide data supports for the healthy and stable growth,development and stability of Gymnocypris namensis,and the stability of the Namtso ecosystem.This paper used the Illumina Miseq platform for high-throughput sequencing of intestinal microorganisms in Gymnocypris namensis,the total number of optimized sequences was 554 607,and the total number of optimized bases was 229 224 641 bp.After DADA2 denoising,a total of 346 272 sequences were generated from 8 samples,and 2 598 ASVs were obtained.A total of 26 phyla,63 classes,134 orders,189 families,251 genera and 361 species were identified.There is significant difference between female and male Desulfosarcinaceae in f_Rubritaleaceae and f_norank_o_norank_c_Berkelbacteria(P＜0.05).Functional prediction results show that the genes encoded by intestinal microorganisms were mostly related to protein processing,synthesis and metabolism,and the relative abundance of translation,ribosome structure and biogenesis,as well as amino acid transport and metabolic functional groups was relatively high.
