Vitamin B₁₂-auxotrophy in dinoflagellates caused by incomplete or absent cobalamin-independent methionine synthase genes (metE).

ABSTRACT: Dinoflagellates are responsible for most marine harmful algal blooms (HABs) and play vital roles in many ocean processes. More than 90% of dinoflagellates are vitamin B₁₂ auxotrophs and that B₁₂ availability can control dinoflagellate HABs, yet the genetic basis of B₁₂ auxotrophy in dinoflagellates in the framework of the ecology of dinoflagellates and particularly HABs, which was the objective of this work. Here, we investigated the presence, phylogeny, and transcription of two methionine synthase genes (B₁₂-dependent metH and B₁₂-independent metE) via searching and assembling transcripts and genes from transcriptomic and genomic databases, cloning 38 cDNA isoforms of the two genes from 14 strains of dinoflagellates, mea
