Abstract: In order to study differential expression in different tissues and period of MyoD Ⅰ gene in Guanling cattle. This study detected the expression of MyoD Ⅰ in longest back muscle, leg muscles, heart, liver, fat and small intestine tissues of Guanling cattle by Real-time quantitative PCR. Meanwhile, analyzed the expressing rules of longest back muscle in foetal, 18 and 30 months. The results showed that the MyoD Ⅰ was expression at high level in longest back muscle and in muscle tissues after birth had high expression, with the extension of born showed an upward trend. It was inferred that the reason of the high expression might be that longest back muscle was muscle enrichment place and increase of muscle fullness.

Key words: Guanling cattle; MyoD Ⅰ gene; Real-time quantitative PCR; expression level
