It has the characteristics of long cashmere fiber, high net cashmere rate, moderate cashmere fineness, white cashmere, strong size, strong adaptability, stable genetic performance, and good effect in improving middle and low production cashmere goat. It is known as “National treasure of China”. With LCG as the paternal parent, five new local breeds have been cultivated, which has made outstanding contributions to the improvement and breeding of Chinese cashmere goat breeds. LCG cashmere has moderate fineness (the average fineness of cashmere of LCG population is about 16 µm).However, as a slightly coarse textile raw material, we hope to identify the key genes regulating cashmere fineness through PCR-seq and MLR, in order to reduce cashmere fineness.We collected and extracted DNA from the blood of Liaoning cashmere goats, designed primers, PCR amplification, and Statistical analysis. It was found that the the AA genotype of the G3667A locus of the <em>KRT35</em> gene, CT genotype of the T615C locus of the <em>TCHHL1</em> gene in bucks and the CC genotype of does, as well as CT genotype of the T615C locus of the <em>TCHHL1</em> gene in bucks and the CC genotype of does are dominant genotypes in cashmere fineness. The dominant haplotype combination with multiple factors and effects of cashmere fineness has been determined to be CTGG in bucks and TTGG in does. There was a significant linear regression relationship between the fineness of cashmere in LCG and the cashmere rate and cashmere quantity.

Our content might be read more properly: This review assembles current knowledge on protein-level changes related to salinity resistance in oil crops. From an extensive analysis of proteomic research, featured here are key genes and cellular pathways which react to salt stress. The literature evinces that cutting-edge proteomic approaches − such as 2D-DIGE, IF-MS/MS, and iTRAQ − have been required to reveal protein expression patterns in oil crops under salt conditions. These studies consistently uncover dramatic shifts in protein abundance associated with important physiological activities including antioxidant defence, stress-related signalling pathways, ion homeostasis, and osmotic regulation. Notably, proteins like ion channels (SOS1, NHX), osmolytes (proline, glycine betaine), antioxidant enzymes (SOD, CAT), and stress-related proteins (HSPs, LEA) play central roles in maintaining cellular balance and reducing oxidative stress. These findings underline the complex regulatory networks that govern oil crop salt tolerance. The application of this proteomic information can inform breeding and genetic engineering strategies to enhance salt resistance. Future research should aim to integrate multiple omics data to gain a comprehensive view of salinity responses and identify potential markers for crop improvement.</div></div>","PeriodicalId":53463,"journal":{"name":"Journal of Genetic Engineering and Biotechnology","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142553736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
