Intragenomic variations of the harmful algal bloom species Phaeocystis globosa through single-strain metabarcoding analysis.

Marine pollution bulletin - 1 Dec 2024

Wang Yifei, Chen Nansheng

Abstract excerpt

Recent studies demonstrated that the existence of high-levels intragenomic variations (IGVs) may lead to overinterpretation of species diversity and genetic diversity in metabarcoding analysis. In this study, IGVs of the V4 region of 18S rRNA gene (18S rDNA V4) in Phaeocystis globosa were ascertained through metabarcoding analysis results of 54 P. globosa strains. Each P. globosa strain harbored over 200 ASVs, in...
