- Abstract
This study was conducted to analyze the regulation mechanisms of TAC1, TACR1, TACR2 and TACR3 genes on reproduction of goat under different photoperiods. The expression conditions of TAC1, TACR1, TACR2 and TACR3 genes in 12 tissues (oviduct, ovary, uterus, gluteus, mesenteric fat, brain, cerebellum, medulla oblongata, hart, lung, liver, kidney) of adult Henan Huai goat under different photoperiods (short day light, Light 8 h:dark 16 h, and long day light, light 16 h dark 8 h) were analyzed by q-PCR method. TTC1, TACR1, TACR2 and TACR3 genes were expressed in all the 12 tissues of goats, with different expression characteristics; and the expression levels of all the genes were affected by photoperiod and changing of light signal between light and dark under short photoperiod. Shifting of light signal from dark to light was more conductive to the expression of these genes in all tissues than that of light signal from light to dark. There were significant differences in the expression levels of genes between light shifting from light to dark and from dark to light when the genes were expressed at a higher level in some tissues. TTC1 and TACR2 genes were expressed at a higher level than TACR1 and TACR3 genes in the various tissues, which implied that TACR2 is a receptor given priority to combine with TAC1 when TAC1 is functional.
