Abstract
Mithun (Bos frontalis) is a semi-wild rare ruminant species. A simple sensitive enzymeimmunoassay suitable for assaying FSH in the blood plasma of mithun is not available which thereby limits our ability to understand this species reproductive processes. Therefore, the aim of this article was to develop a simple and sensitive enzymeimmunoassay (EIA) for estimation of FSH in mithun plasma and apply the assay to understand the estrous cycle and superovulatory process in this species. To accomplish this goal, biotinylated FSH was bridged between streptavidin-peroxidase and immobilized antiserum in a competitive assay. Forty microlitre mithun plasma was used directly in the EIA. The FSH standards were prepared in hormone free plasma and ranged from 5-1280 pg/well/40 μL. The sensitivity of EIA was 5 pg/well FSH, which corresponds to 0.125 ng/mL plasma and the 50% relative binding sensitivity was 90 pg/well/40 μL. Although the shape of the standard curve was not influenced by different plasma volumes viz. 40 and 80 μL, a slight drop in the OD450 was observed with the increasing volume of plasma. Parallelism tests conducted between the endogenous mithun FSH and bovine FSH standards showed good homology between them. Plasma FSH estimated using the developed EIA and commercially available FSH EIA kit in the same samples were correlated (r = 0.98) and showed linearity. Both the Intra- and inter-assay CV were below 6%. Recovery of known concentrations of added FSH showed linearity (r = 0.99). The developed EIA was further validated biologically by estimating FSH in cyclic cows for the entire estrous cycle, in mithun heifers administered with GnRH analogues and in mithun cows during superovulatory treatment with FSH. In conclusion, the EIA developed for FSH determination in mithun blood plasma is simple and highly sensitive for estimation of mithun FSH in all physiological conditions.

Abstract
The mammalian major histocompatibility complex (MHC) plays important roles in pathogen recognition and disease resistance. In the present study, the coding sequence and the 5′- and 3′-untranslated regions of MHC class II DR alpha chain (the DRA gene) from rare gayal and gaytle were cloned and analyzed to dissect structural and functional variations. The nucleotide and amino acid sequences for the DRA genes in gayal (Bofr-DRA) and gaytle (Bofr × BoLA-DRA) were almost identical to those for cattle and yak (99%). Compared to yak, two amino acids substitutions in the signal peptide (SP) domain for gayal were found within all Bos animals. Except for only one replacement in the amino acid within the α2 domain of the DRA protein in gayal, the additional residues were highly conserved across the species investigated. The 20 peptide-binding sites (PBS) of Bofr-DRA and Bofr × BoLA-DRA were essentially reserved in the α1 domain among all species investigated. The lesser degree of substitution in Bofr-DRA is concordant with the concept that the DRA gene is highly conserved among all mammals. The very high degree of conservativity of the DRA gene among ruminants, including gayal, suggests its recent evolutionary separation.

Abstract
In the present study, exon 2 of major histocompatibility complex (MHC) class II DQB gene from 39 gayals (Bos frontalis) was isolated, characterized and compared with previously reported patterns for other bovidae. It was revealed by sequence analyses that there are 36 DQB exon 2 variants among 39 gayals. These variants exhibited a high degree of nucleotide and amino acid substitutions with most amino acid variations occurring at positions forming the peptide-binding sites (PBS). The DQB loci were analysed for patterns of synonymous (dS) and non-synonymous (dN) substitution. The gayals were observed to be under strong balancing selection in the DQB exon 2 PBS (dN = 0.094, P = 0.001). It appears that this variability among gayals could confer the ability to mount immune responses to a wide variety of peptides or pathogens.

Abstract
The melanocortin 1 receptor gene (MC1R) plays a crucial role in determining coat colour of mammals. To investigate the relationship of polymorphism of the MC1R with coat colour in gayal, the coding sequence (CDS), and the 5'- and 3'-untranslated regions (UTR) of the MC1R were sequenced from 63 samples from the gayal and compared with the sequences of the MC1R from other ruminant species. A sequence of 1,136 bp including the whole CDS (954 bp) and parts of the 5'- and 3'-UTR (164 and 18 bp, respectively) of the gayal MC1R was obtained. A total of nine single nucleotide polymorphisms (SNPs) including four SNPs (c.-129T>C, c.-127A>C, c.-106C>T, c.-1G>A) in the 5'-UTR and five SNPs (c.201C>T, c.583C>T, c.663T>C, c.871A>G and c.876T>C) in the CDS were detected, revealing high genetic diversity. Three novel coding SNPs including c.201C>T, c.583C>T and c.876T>C, which have not been reported previously in bovid species, were retrieved. Within five coding SNPs, c.201C>T, c.663T>C and c.876T>C were silent mutations, while c.583C>T and c.871A>G were mis-sense mutations, resulting in changes in the amino acids located in the fifth (p.L195F) and seventh (p.T291A) transmembrane regions, respectively. The alignment of amino acid sequences was found to be very similar to those for other bovid species. It was demonstrated, using the functional effect prediction, that the p.T291A amino acid replacement could have an effect on MC1R protein function but not for the p.L195F substitution. Using phylogenetic analyses it was revealed that the gayal has a close genetic relationship with the yak. However, three classical bovine MC1R loci the E (D), E (+) and e were not retrieved in the gayal, indicating other genes or factors could affect coat colour in this species.

Abstract
The gene coding for insulin-like growth factor-binding protein 3 (IGFBP3) is important for regulation of growth, development and metabolism in mammals. The present investigation was conducted to study nucleotide polymorphism of the IGFBP3 in gayal (Bos frontalis) and to compare the variations with those which occur in other ruminants. A fragment of 645 base pairs of the IGFBP3 covering a part of exon 2, the complete intron 2 and exon 3 and a part of intron 3 was amplified, sequenced (n=46) and digested (n=79) with HaeIII restriction enzyme from 125 collected gayal samples. Nine single nucleotide polymorphisms (SNPs) [C14T, A122C, C137T, G144C, C155T, G213A, C279A, G334A and G460A] were identified and located in intron 2, revealing high genetic variability. The alignment of nucleotide sequences was found to be very similar to those for other bovid species. Sequencing and HaeIII digestion showed that frequency of alleles C and A [consisting of fragments of sizes 56, 64, 228, 264, 282, 298 and 497 bp (CC genotype)] was 0.96 and 0.04 for the SNP C279A. Moreover, the genotype frequency of the SNP C279A in gayal was compared with that in other ruminants and it appears that this polymorphism may be associated with low fat content and rapid growth in this rare species.

Abstract
The gayal (Bos frontalis) is a rare semi-wild bovid species in which bovine spongiform encephalopathy (BSE) has not been reported. Polymorphisms of the prion protein gene (PRNP) have been correlated significantly with resistance to BSE. In this study, the coding region of PRNP was cloned and characterized in samples from 125 gayal. A total of ten single nucleotide polymorphisms (SNPs), including six silent mutations (C60T, G75A, A108T, G126A, C357T and C678T) and four mis-sense mutations (C8A, G145A, G461A and C756G), corresponding to amino acids T3K, G49S9, N154S and I252M were identified, revealing high genetic diversity. Three novel SNPs including C60T, G145A and C756G, which have not been reported previously in bovid species, were retrieved. There also was one insertion-deletion (187Del24) at the N-terminal octapeptide repeat region. Alignment of nucleotide and amino acid sequences showed a high degree of similarity with other bovid species. Using phylogenetic analyses it was revealed that gayal has a close genetic relationship with Zebu cattle. In short, preliminary information is provided about genotypes of the PRNP in gayal. This could assist with the study of the pathogenesis of transmissible spongiform encephalopathies and cross species transmission as well as a molecular breeding project for gayal in China.
