Investigating InDels in YAP and TAZ genes and their impact on growth characteristics in goats

Abstract

Abstract. Yes-associated protein (YAP) and a transcriptional co-activator with PDZ-binding motif (TAZ) genes are crucial for regulating the size of mammalian tissues and organs as well as for many biological processes such as bone formation, cell lineage determination, tissue regeneration, and cell proliferation. The purpose of this study was to characterize the YAP and TAZ gene polymorphisms in 266 Guanzhong Dairy Goats and 299 Shanbei White Cashmere Goats and to explore their potential relationship with growth characteristics such as body weight and body length. After genotyping and using PCR amplification and Sanger sequencing to find polymorphisms in the YAP and TAZ genes, five InDels loci were found in the goat YAP gene and three InDels loci in the TAZ gene. The findings of the association analysis demonstrated that the goats' body weight, height, cannon circumference, chest depth, chest breadth, and chest circumference were all substantially influenced by five InDels loci in the YAP gene (p<0.05). Goat body height, trunk breadth, trunk length, body length, and body weight were all substantially impacted by three InDels loci in the TAZ gene (p<0.05). In conclusion, eight InDels loci of goat YAP and TAZ were found in this study, and their impacts on goat phenotype were disclosed. These results might offer fresh avenues for boosting goat molecular breeding.
