Positive Selection in Plant Evolution
植物进化中的正选择作用

Positive selection fixes an allele harboring an advantageous mutation that increases individual fitness. Research into positive selection helps us understand processes of evolution. This paper reviews positive selection found in plant genes in recent years. Positive selections discovered in genes of land plants and algae are summarized, respectively. The positive selection genes found in land plants are mainly related to reproduction and resistance. This review will help further research into the search for loci under positive selection.
