Abstract Text:

This study aimed at finding some novel molecular markers associated with wool traits and providing  molecular bases for improved wool quality of sheep. Comparative study of 13 candidate genes was designed to evaluate the different fineness in skin tissue of wool sheep applying 18SrRNA,β-Actin and GAPDH as multi-reference normalization and to detect their expression. The results indicated that significant differences were observed in TXNIP, PIK3CA, TFDP1, ADAM9, FAIM and FZD3 expression in different fineness of wool in the skin tissues of sheep.  Comparing the type of wool fineness in sheep, the expression levels of TXNIP, TFDP1 and FAIM gene were higher in the skin tissues of superfine type wool sheep, the expression levels of PIK3CA, ADAM9 and FZD3 genes were higher in the skin tissues of fine type wool sheep. The rest of 7 candidate genes showed no significant difference between the two types.
