This species shows a very peculiar biology and a great capacity for environmental adaptation. There has been an increasing economic interest as well as a growing demand for a more detailed knowledge of molecular features in this species. From this perspective we report a genomic, transcriptional and cytogenetic analysis of 5 master genes involved in skeletal muscle development. Of these 5 genes, <i>MYOD1</i>, <i>MYF5</i>, <i>MYF6</i> and <i>MYOG</i> belong to the basic helix-loop helix protein family while <i>MSTN</i> belongs to the TNF-B protein family. In mammals, these genes are involved in the early stages of skeletal muscle differentiation, development and regeneration. These pivotal biological functions are finely regulated in a tissue- and temporal-specific manner. We used a comparative genomic approach to obtain the buffalo specific sequences of <i>MYOD1</i> and <i>MYF6</i>. The nucleotide sequence similarity and the protein domain conservation of the newly obtained sequences are analysed with respect to bovine and other mammalian species showing sequence similarity. The presence of a polymorphism in <i>MYOD1</i> coding sequence is described and its possible effect discussed. Using a quantitative PCR approach, we compared the level of the 5 transcripts in adult and fetal muscle. These genes were physically localised on river buffalo R-banded chromosomes by FISH using bovine genomic BAC-clones. Here, we present a genomic and cytogenetic analysis which could offer a background to better characterise the buffalo genes involved in muscle function and which may be responsible for buffalo-specific meat features.
