Novel SNP identification in exon 3 of HSP90AA1 gene and their association with heat tolerance traits in Karan Fries (Bos taurus × Bos indicus) cows under tropical climatic condition

A dairy improvement program designed to develop a breed of cattle adapted to tropical environments is described. Each year young crossbred (Bos indicus x Bos taurus) bulls are screened for heat tolerance and tick resistance, and then progeny-tested in the herds of cooperating dairy farmers. Estimates of phenotypic and genetic means, variances and correlations are presented for production of milk and milk components, and the rate of genetic improvement is discussed. In particular the heritability of milk yield in the crossbred progeny is 0.27, and the theoretical rate of improvement is 2.6% per year. ____________________ *Part III, Aust. J. Agric.

The objective of this study was to characterize and validate the candidate point mutation in Calcium channel, voltage-dependent, alpha-2/ delta subunit 1 (CACNA2D1) gene in Karan Fries (Bos taurus x Bos indicus) cattle. The CACNA2D1 gene reported as one of the potential candidate gene influencing Somatic cell Score and Mastitis. A PCR product of 249 bp amplifying the exon 19 and partial 18 and 19 intronic region of CACNA2D1 gene was digested with Hae III restriction enzyme to screen the reported point mutation. A monomorphic banding pattern with genotype AA was found in Karan Fries cattle. Sequencing was also carried out to characterize and explore insilico screened mutation in the nucleotide sequence of a particular region. The result indicates highly conserved sequence in Karan Fries cattle. The Phylogenetic tree revealed that Karan Fries cattle were closer to Bos taurus cattle, Bos mutus (Yak), and Bison bison (American buffalo) compared to other species.

Background: Forebrain embryonic zinc finger-like (FEZL) gene is an important candidate associated with mastitis resistance in dairy cattle. FEZL is involved in transcriptional regulation of neuronal development and there exists a crosstalk between neuronal development and immunity via downstream cytokine expression. A single glycine insertion into glycine stretch of FEZL gene has large effect on downstream cytokine pathway making the cows susceptible to mastitis. The present study was aimed to sequence characterize FEZL gene in Sahiwal (Bos indicus) and Karan Fries (Bos inidcus X Bos taurus) cattle.Methods: Sequence characterization of bovine FEZL gene was carried out by primer walking method. Ten sets of oligonucleotide primers were designed to synthesize overlapping fragments and generate the complete sequence of about 3.7 kb covering all exons and 5’ upstream regulatory and flanking regions.Result: A total of eight nucleotide variations including three INDELS and five substitution mutations were observed among FEZL gene sequences of Bos taurus, Bos indicus (Sahiwal) and Bos taurus X Bos indicus (Karan Fries) cattle. The conceptualized amino acid sequence of bovine FEZL gene in Sahiwal and Karan Fries cattle was found to have 13 tandem Glycine residues and a serine to proline change within exon 1 region. The percent identity of FEZL gene of Sahiwal and Karan Fries cattle was 99% with that of Bos taurus, 95% with dog, horse and pig, 94% with human, 93% with rabbit, 92% with marmoset, 89% with rat and 79% with chicken. Sequence characterization of ~0.7 kb 5’ flanking region showed that it is highly conserved among bovines and resulted in prediction of six putative sites for binding of transcription factors (including Elk-1, Oct-1, HNF4, Lmo2 complex, GATA-3 and Nkx2-5). Elucidation of Bos indicus FEZL gene will further form the basis to identify candidate gene markers for association with mastitis resistance/susceptibility in cattle.

Brucella abortus S19 strain vaccination is most effectively used as a tool to control the brucellosis in cattle. To understand the genetic basis of differences in immune responsiveness after immunization in cattle of different genotypes, we assessedthe expression of MHC-DRB3 antigen receptor molecule in six each female calves of Karan Fries crossbreds (KF, Bos indicus x Bos taurus) and Sahiwal (Bos indicus) vaccinated with Brucella S19. Serum and peripheral blood mononuclear cells (PBMC) were isolated from blood collected on 0(before vaccination) and 7, 14 and 28 day of vaccination. Antigenic response was assessed for these days in both the groups using Rose Bengal Plate form Test (RBPT). At 0d, the calves of both groups showed no antigen agglutination, confirming the calves free from the infection.The serum of 7d onward started showing the agglutination with more strong response in later stages specifically in KF, indicating increased immune response against Brucella. Therefore, RBPT can be used as earliest screening (7d onward) for Brucella antigenic reactivity in both cattle groups. The expression of DRB3 gene started with slight upregulation after vaccination,in general, however without any significant differences between two different genetic groups upto14d.The significant (p Lass Than 0.01) higher expression (8 times) of DRB3was observed in KF than Sahiwal at 28d. The study indicated that antigenic reactivity and MHC-DRB3 expression elicited by Brucella S19 vaccination was more prominent in KFduring initial days, which may provide an extra advantage to the host for antigen binding, thereby better immune protection at later stage.

Abstract Background Cyclin-dependent kinases (CDKs) are protein kinases regulating important cellular processes such as cell cycle and transcription. Many CDK genes also play a critical role during adipogenic differentiation, but the role of CDK gene family in regulating bovine adipocyte differentiation has not been studied. Therefore, the present study aims to characterize the CDK gene family in bovine and study their expression pattern during adipocyte differentiation. Results We performed a genome-wide analysis and identified a number of CDK genes in several bovine species. The CDK genes were classified into 8 subfamilies through phylogenetic analysis. We found that 25 bovine CDK genes were distributed in 16 different chromosomes. Collinearity analysis revealed that the CDK gene family in Bos taurus is homologous with Bos indicus, Hybrid-Bos taurus, Hybrid Bos indicus, Bos grunniens and Bubalus bubalis. Several CDK genes had higher expression levels in preadipocytes than in differentiated adipocytes, as shown by RNA-seq analysis and qPCR, suggesting a role in the growth of emerging lipid droplets. Conclusion In this research, 185 CDK genes were identified and grouped into eight distinct clades in Bovidae, showing extensively homology. Global expression analysis of different bovine tissues and specific expression analysis during adipocytes differentiation revealed CDK4, CDK7, CDK8, CDK9 and CDK14 may be involved in bovine adipocyte differentiation. The results provide a basis for further study to determine the roles of CDK gene family in regulating adipocyte differentiation, which is beneficial for beef quality improvement.
