Comparative evaluation of 18S rDNA V4 and 28S rDNA D1–2 regions for resolving Alexandrium species diversity to improve its use for metabarcoding
Key Points
Resolution of alexandrium species diversity improved using the 18S rDNA V4 region.
The 28S rDNA D1–2 region also effectively identifies species but with some limitations.
Comparative evaluation includes analysis of genetic markers across various samples.
Enhanced metabarcoding capabilities can lead to better monitoring of harmful algal blooms.
