Population genetic analysis of branchiostoma from three regions of China based on SLAF-SEQ

Key Points

• This research aims to analyze the genetic diversity and structure of Branchiostoma populations in three regions of China using SLAF-seq technology.
• Conducted genome-wide SNP marker development and genetic analysis based on SLAF-seq technology.
• Compared COI sequences from sampled populations to assess genetic relationships.
• Performed population structure analysis to evaluate genetic differentiation among locations.
• Xiamen population exhibited the highest genetic diversity, followed by Qingdao and Changli.
• All populations had observed heterozygosity (Ho) lower than expected heterozygosity (He), indicating potential genetic constraints.
• Moderate genetic differentiation was found between Xiamen and the other two populations (Fst), while Changli and Qingdao showed weak differentiation.
