Due to the phenotype-based artificial selection in domestic cattle, the underlying functional genes may be indirectly selected and show decreasing diversity in theory. The growth hormone receptor (GHR) gene has been widely proposed to significantly associate with critical economic traits in cattle. In the present study, we comparatively studied the genetic(More)
ATP synthase 8 (ATP8) and ATPase synthase 6 (ATP6) play an important role in mitochondrial ATPase assembly. Mutations in either of these units could affect the ATP processing and the respiration chain in mitochondria. To find out if there were differences in gene diversity between Tibetan yaks and domestic cattle, we sequenced the ATP8 and ATP6 genes in 66(More)
The objective of this study was to compare carcass composition and meat quality traits in the longissimus dorsi and biceps femoris muscles in the Hyla, Champagne and Tianfu Black rabbit breeds. Tianfu Black rabbits had the heaviest head, skin, thoracic viscera and commercial carcass percentage (p<0.05). In addition, Tianfu Black had the highest pH0 h value,(More)
It is widely acknowledged that transcriptional diversity largely contributes to biological regulation in eukaryotes. Since the advent of second-generation sequencing technologies, a large number of RNA sequencing studies have considerably improved our understanding of transcriptome complexity. However, it still remains a huge challenge for obtaining(More)
The transcript assembly is essential for transcriptome studies trom next-generation sequencing data. However, there are still many faults of algorithms in the present assemblers, which should be largely improved in the future. According to the requirement of reference genome or not, the transcript assembly could be classified into the genome-guided and de(More)
Although various computer tools have been elaborately developed to calculate a series of statistics in molecular population genetics for both small- and large-scale DNA data, there is no efficient and easy-to-use toolkit available yet for exclusively focusing on the steps of mathematical calculation. Here, we present PopSc, a bioinformatic toolkit for(More)
The leptin (LEP) gene encodes a protein that greatly affects the regulation of body weight, energy balance, and food intake in mammals. The objective of the present work was to identify genetic variants of the caprine LEP gene in 411 individuals from five Chinese goat breeds. Six novel single nucleotide polymorphisms (SNPs) (g.117T > C, g.1642G > A, g.2883G(More)
Clustering of 16s rRNA amplicon sequences into operational taxonomic units (OTUs) is the most common bioinformatics pipeline for investigating microbial community by high-throughput sequencing technologies. However, the existing algorithms of OTUs clustering still remain to be improved at reliability. Here we propose an improved method (bioOTU) that first(More)
The objective of this study was to investigate the effect of the polymorphism in the Myf5 gene on meat quality traits in the Ira and Tianfu Black rabbit breeds using polymerase chain reaction and DNA sequencing. A total of six SNPs and four haplotypes were found in Ira rabbits and only two SNPs were found in Tianfu Black rabbits. The two rabbit breeds had(More)
Owing to wide application of RNA sequencing (RNA-seq) technology, more and more eukaryotic genomes have been extensively annotated, such as the gene structure, alternative splicing, and noncoding loci. Annotation information of genome is prevalently stored as plain text in General Feature Format (GFF), which could be hundreds or thousands Mb in size.(More)
