We here describe the molecular characteristics of rRNA gene, including the internal transcribed spacers (ITS) in this genus and a comparison was made with associated species sequences registered in the GenBank. Like many other species of this genus, Caulerpa taxifolia has some unique growth characteristics, besides being siphonous, that promote its … Introduction. Despite recent advances in taxonomy and phylogeny, there is still confusion about the delimitation and identification of some species due to tremendous phenotypic plasticity. Crossref Nicholas A.
