Xu Q., and Cai R.X., 2024, Impact of domestication on nucleotide diversity in barley, Triticeae Genomics and Genetics, 15(1): 56-65 (doi: 10.5376/tgg.2024.15.0006)

As a widely cultivated crop worldwide, barley (Hordeum vulgare) has a long history of domestication and has had a profound impact on agricultural production and human life. With the development of molecular biology technology, research on nucleotide diversity in barley has gradually deepened, providing important basis for understanding the genetic structure and domestication mechanism of barley. This study aims to analyze the impact of domestication on nucleotide diversity in barley. By comparing and analyzing the nucleotide diversity of wild barley and cultivated barley, it is found that population bottlenecks and targeted breeding during domestication have a profound impact on genetic structure. Meanwhile, the changes in adaptive genes and genomic structure of barley caused by domestication were explored, revealing the impact of domestication mechanisms on crop genetics. This study aims to enhance the understanding of the genetic mechanism of barley domestication, and provide scientific basis for variety improvement and genetic resource protection. In addition, it has reference value for other crop domestication and genetic diversity research, and is of great significance for promoting the development of agricultural biotechnology.
