M., and Amaral-Trusty, M. E. J., Sequence analysis of the S1PR1 gene in river buffalo, vol. 15, p. -, 2016.

Recent developments in methodologies for genomic analyses have enabled a significant advance in understanding of the river buffalo genome. The S1PR1 gene has been mapped to buffalo chromosome 6 and bovine chromosome 3; this gene is of interest as it is a candidate for marbling in meat, an important economic trait. Here, we performed next generation sequencing in a buffalo BAC DNA clone and obtained a 54.5-kb sequence encompassing the entire buffalo S1PR1 gene as well as the 27 kb upstream region and the 22 kb downstream region.

Molecular characterization of interferon regulatory factor 1 in Bubalus bubalis

N. B. Stafuzza, Borges, M. M., and Amaral-Trusty, M. E. J., Molecular characterization of interferon regulatory factor 1 in Bubalus bubalis, vol. 14, pp. 10919-10928, 2015.

Interferon regulatory factor 1 (IRF1) is functionally diverse in the regulation of immune response and is considered to be an important candidate gene for studying disease susceptibility in mammals. In this paper, we characterized the whole sequence of the IRF1 gene in river buffalo (Bubalus bubalis) and compared genomic and the amino acid sequences between different species. The buffalo IRF1 gene was 7099 bp long and organized into 10 exons and nine introns.

Comparative analysis of the river buffalo somatostatin gene

N. B. Stafuzza, Borges, M. M., and Amaral, M. E. J., Comparative analysis of the river buffalo somatostatin gene, vol. 13, pp. 10017-10024, 2014.

The somatostatin protein plays a crucial role in the regulation of multiple biological functions, such as growth, fat deposition, and nutrient absorption in vertebrates. Polymorphisms in the somatostatin gene have been associated with growth traits in livestock species, including cattle and goat. In this study, we conducted complete molecular characterization of the somatostatin gene in Bubalus bubalis (Murrah breed) by sequencing a Murrah BAC clone spanning 72,489 base pairs (bp) in length.

Sequence characterization and comparative analysis of the gastrotropin gene in buffalo (Bubalus bubalis)

N. B. Stafuzza, Borges, M. M., and Amaral-Trusty, M. E. J., Sequence characterization and comparative analysis of the gastrotropin gene in buffalo (Bubalus bubalis), vol. 13, pp. 10934-10942, 2014.

In this study, we compared the complete sequence of the FABP6 gene from an animal representing the Murrah breed of the river buffalo (Bubalus bubalis) with the gene sequence from different mammals. The buffalo FABP6 gene is 6105 bp in length and is organized into four exons (67, 176, 90, and 54 bp), three introns (1167, 1737, and 2649 bp), a 5ꞌUTR (93 bp), and a 3ꞌUTR (72 bp). A total of 22 repetitive elements were identified at the intronic level, and four of these (L1MC, L1M5, MIRb, and Charlie4z) were identified as being exclusive to buffalo.

Construction and preliminary characterization of a river buffalo bacterial artificial chromosome library

N. B. Stafuzza, Abbey, C. A., Gill, C. A., Womack, J. E., and Amaral, M. E. J., Construction and preliminary characterization of a river buffalo bacterial artificial chromosome library, vol. 11, pp. 3013-3019, 2012.

River buffalo genome analyses have advanced significantly in the last decade, and the genome sequence of Bubalus bubalis will be available shortly. Nonetheless, large-insert DNA library resources such as bacterial artificial chromosomes (BAC) are still required for validation and accurate assembly of the genome sequence. We constructed a river buffalo BAC library containing 52,224 clones with an average insert size of 97 kb, representing 1.7 × coverage of the genome.
