Abstract:

Cashmere fineness is the key quantitative trait to evaluate cashmere quality and cashmere price.In recent years,with the intensive study of cashmere fineness functional marker genes and through the genome-wide association analysis,the candidate genes of fineness traits of cashmere were gradually screened out.But the key regulated genes,their expression levels and molecular regulation mechanisms of cashmere fineness have not been resolved.Gene expression is regulated by a variety of regulatory factors.The regulation of non-coding RNA is more active,it mainly includes microRNA,lncRNA and circRNA.High throughput sequencing and biological information analysis discovered that non-coding RNA is differential expressed and regulated of related target genes of skin,secondary hair follicle and the development of secondary hair follicle in periodic growth in different cashmere fineness of individual in cashmere goat breeds and varieties.At present,the related researchs of using SNP marker,transcriptional screening,high throughput analytical non-coding RNA and genome-wide association analysis to selected differential genes of cashmere fineness have found that the same cashmere fineness target genes focus on two pathways were more,but it was very rare to cover two or more passages.In this paper,the authors mainly discussed the research progress on molecular regulation mechanism of cashmere fineness candidate genes,and microRNA,lncRNA and circRNA on cashmere fineness related target genes at transcriptional level.

Key words: cashmere fineness; target gene; microRNA; lncRNA; circRNA
