| The exon 2-3 region of bovine major histocompatibility complex (MHC) class I BoLa-A gene was investigated for polymorphisms in three breeds of cattle originated in the Indian subcontinent namely Sahiwal, Tharparkar, Hariana, as well as crossbred (Bos taurus x Bos indicus) cattle and Jersey, the exotic breed (Bos taurus). The PCR amplified fragment of 714 bp showed distinct DdeI-, TaqI- and HinfI- RFLP patterns, thus confirming a higher degree of polymorphism in this region. To our knowledge this is the first report of HinfI restriction patterns for BoLa-A exon 2-3. The sequencing results revealed a number of nucleotide substitutions in this region, which resulted in amino acid changes. The present investigation confirmed that MHC class I BoLa-A exon 2-3 is... |

| Leptin plays an important role in the regulation of feed intake, energy metabolism, growth and reproduction of cattle. We used the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique to screen for DNA polymorphisms of the leptin gene in 403 cattle belonging to various breeds of Bos indicus (Hariana, Sahiwal, Gir and Nimari cattle), Bos taurus (Holstein Friesian (HF) and Jersey cattle) as well as Bos taurus x Bos indicus crossbreds (½ HF x ½ Hariana). In all the cattle we amplified two regions of the leptin gene, a 522 bp fragment comprising the partial intron 2 and exon 3 and another 94 bp fragment consisting of part of exon 2. Digestion of 522 bp PCR products with the BsaAI restriction enzyme revealed three genotypes in... |
