Abstract: -The objective of this work was to estimate the allelic and genotypic frequencies of CAST/XmnI, a calpastatin gene polymorphism, and CAPN530, a calpain 1 large subunit gene polymorphism, in different beef genetic groups (Nelore and Nelore x Bos taurus), and to investigate associations between these polymorphisms and carcass and meat traits. Three hundred animals -comprising 114 Nelore, 67 Angus x Nelore, 44 Rubia Gallega x Nelore, 41 Canchim, 19 Brangus three-way cross and 15 Braunvieh three-way cross -were ge… Show more

“…Most studies on the evaluation of different genes (LEP, HSP90AA1, FABP4, GH1, HSPB1, MYF5, MYF5, DNAJA1, DGAT1, HRSP12, ADAMTS4, etc., mainly CAPN, CAST and their isoforms) and their SNPs as markers for tenderness traits were performed until about 2010 (e.g., [ 45 , 46 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 ]), but later, related papers were also published on cattle of different breeds and in other geographic locations [ 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 ]. The new research groups are especially focused on the use and improvement of genomic selection [ 32 , 44 , 77 , 78 , 79 , 80 , 81 ] and also on the use of RNA sequencing technology to identify the mechanisms involved in gene expression for beef tenderness [ 82 , 83 , 84 ].…”
