Abstract
Simple SummaryAKAP12, the family of A-kinase anchoring proteins (AKAPs), plays an important role in the regulation of growth and development. There have been no corresponding studies of the effect of the AKAP12 gene on growth traits in goats. In our previous study, 7 bp (intron 3) and 13 bp (3′UTR) indels within the AKAP12 gene significantly influenced AKAP12 gene expression. This study expected to identify the association between these two genetic variations and growth-related traits in 1405 Shaanbei white cashmere (SBWC) goats. The P1–7 bp indel locus was significantly correlated with height at hip cross (HHC; p < 0.05) and the P2–13 bp indel locus was associated with body weight, body length, chest depth, chest width, hip width, chest circumference and cannon (bone) circumference in SBWC goats (p < 0.05). These results prove that the AKAP12 gene plays an important role in the growth and development of goats.The A-kinase anchoring protein 12 gene (AKAP12) is a scaffold protein, which can target multiple signal transduction effectors, can promote mitosis and cytokinesis and plays an important role in the regulation of growth and development. In our previous study, P1–7 bp (intron 3) and P2–13 bp (3′UTR) indels within the AKAP12 gene significantly influenced AKAP12 gene expression. Therefore, this study aimed to identify the association between these two genetic variations and growth-related traits in Shaanbei white cashmere goats (SBWC) (n = 1405). Herein, we identified two non-linkage insertions/deletions (indels). Notably, we found that the P1–7 bp indel mutation was related to the height at hip cross (HHC; p < 0.05) and the P2–13 bp indel was associated with body weight, body length, chest depth, chest width, hip width, chest circumference and cannon (bone) circumference in SBWC goats (p < 0.05). Overall, the two indels’ mutations of AKAP12 affected growth traits in goats. Compared to the P1–7 bp indel, the P2–13 bp indel is more suitable for the breeding of goat growth traits.
Highlights
The Shaanbei white cashmere (SBWC) goat is among the well-known breeds for both cashmere and meat in Northwest China
Thereby we provide a theoretical basis for the application of molecular marker breeding in SBWC goats
Two indel loci were found to be polymorphic in SBWC goats and named P1–7 bp indel (NC_030816:g.83323del ACTGCTG, intron 3) and P2–13 bp indel (NC_ 030816.1: g.110266del TGGTCTTTTTGTG, 30 UTR) in the A-kinase anchoring protein 12 gene (AKAP12) goats, respectively
Summary
The Shaanbei white cashmere (SBWC) goat is among the well-known breeds for both cashmere and meat in Northwest China. The population of SBWC goats in Yulin is nearly 10 million. Is among the most accurate and repaid methods which could satisfy the need to screen genes and consider the relationship between polymorphisms and growth-related traits. We propose that establishing an MAS system will speed up the development of goat breeding [2]. It can be applied to the identification of functional genes that control traits, which is conducive to the further development and utilization of excellent genes, and is widely used in the fields of animal and plant population genetic analysis, molecular assisted breeding and human forensic genetics [4,5,6]
