Abstract:

Luchuan pig myoblast determining gene 1(MyoD1)was cloned,bioinformatics analysis was performed,and its expression was analyzed in different tissues of Luchuan pigs,to explore the role of MyoD1 gene in the growth and development of skeletal muscle.Published MyoD1 gene of wild boar sequence on NCBI as the template,designed specific primer,cloned the CDS region of MyoD1,and compared the similarity with wild boar,cattle,sheep,human,mouse and rat gene sequence,constructed system tree for bioinformatics analysis by online software.Then,the relative expression of MyoD1 gene in different tissues of Luchuan pigs by RT-PCR.The CDS of MyoD1 gene in Luchuan pig was 960 bp,encoding 319 amino acids,five base mutations.The similarities of MyoD1 genes between Luchuan pig and wild boar,cattle,sheep,human,mouse and rats were 99.2%,93.0%,92.3%,90.0%,84.3% and 84.0%,respectively.Total number of MyoD1 gene atoms in Luchuan pigs was 4 680,molecular mass of the protein was 33.99 ku,molecular formula was C1457H2296N442O471S14;the instability coefficient was 63.87,indicating a lack of stability;isoelectric point was 5.63,which belongs to the acidic protein;no transmembrane structure existed,found 35 phosphorylation sites and 1 glycosylation site;protein secondary structure was dominated by an irregular coil,which accounting for 60.69%.The MyoD1 gene in Luchuan pigs had the highest expression in the longest dorsal muscle,which was significantly higher than in other tissues,while kidney had the lowest expression.MyoD1 gene was expressed in all tissues of Luchuan pigs and mainly in the longest dorsal muscle,we speculated that MyoD1 gene might play a crucial role in the muscle growth and development of Luchuan pigs.

Key words: Luchuan pig, MyoD1 gene, Bioinformatics analysis, Gene cloning, Organizational expression
