RESUMO
Mongolian pharmacy is an important part of traditional medicine for the Chinese nation, with a long history and a complete theoretical system. The Mongolian people have accumulated and summarized the types and usage of Mongolian medicines in the practice of fighting against diseases over a long history. Mongolian medicinal resources are rich and diverse, the processing is self-contained, and the methods of medication are scientific and reasonable. Mongolian pharmacy not only has a deep historical relationship with traditional Chinese medicine but has also absorbed the essence of ancient Tibetan and Indian Ayurvedic medicine in the process of its development. We can identify the historical traces of the continuous exchange, communication, and integration of various ethnic medicinal cultures from the names of Mongolian medicinal materials. Because of the differences in languages and cultures of the various ethnic groups, the names of Mongolian medicinal materials have undergone a long historical period of evolution. These need to be further standardized owing to complications caused by the existence of synonyms and homonyms.
RESUMO
Pigeon breed resources provide a genetic model for the study of phenomics. The pectoral muscles play a key role for the meat production performance of the meat pigeon and the athletic ability of the High flyers. Euro-pigeons and Silver King pigeons are commercial varieties that exhibit good meat production performance. In contrast to the domestication direction of meat pigeons, the traditional Chinese ornamental pigeon breed, High flyers, has a small and light body. Here, we investigate the molecular mechanism of the pectoral muscle development and function of pigeons using whole-genome and RNA sequencing data. The selective sweep analysis (F ST and log2 (θπ ratio)) revealed 293 and 403 positive selection genes in Euro-pigeons and Silver King, respectively, of which 65 genes were shared. With the Silver King and Euro-pigeon as the control group, the High flyers were selected for 427 and 566 genes respectively. There were 673 differentially expressed genes in the breast muscle transcriptome between the commercial meat pigeons and ornamental pigeons. Pigeon genome selection signal combined with the breast muscle transcriptome revealed that six genes (SLC16A10, S100B, SYNE1, HECW2, CASQ2 and LOC110363470) from commercial varieties of pigeons and five genes (INSC, CALCB, ZBTB21, B2M and LOC110356506) from Chinese traditional ornamental pigeons were positively selected which were involved in pathways related to muscle development and function. This study provides new insights into the selection of different directions and the genetic mechanism related to muscle development in pigeons.
RESUMO
BACKGROUND: To investigate the molecular mechanisms determining the coat color of native breed sheep in Xinjiang. METHODS: Bashibai sheep, Yemule white sheep and Tulufan black sheep were selected. Illumina HiSeq X Ten sequencing technology was used to detect the genes responsible for the white, light brown, black and cyan gray coat colors in sheep. Sequence analysis and functional gene annotation analysis were performed to analyze the results. The signal pathways and differentially expressed genes related to sheep hair color production regulation were screened and finally verified by real-time polymerase chain reaction. RESULTS: Functional annotation by Kyoto Encyclopedia of Genes and Genomes analysis revealed significant differences in enrichment of immunity-related pathways as well as melanogenesis synthetic and tyrosine metabolism pathways. Our results showed that the DCT, TYR, TYRP1, PMEL, SLC45A2 and MLANA six genes may be associated with the regulation of coat color development and provide a theoretical basis for selecting natural coat colors of sheep.
