Assessing the utility of mitochondrial gene markers in the family Suessiaceae (Dinophyta) with phylogenomic validation

Assessment of biodiversity, global distribution, and putative ecological niches of suessiacean dinoflagellates by DNA metabarcoding

“…This is because many suessiacean species are belong to monospecific genera. Moreover, in some genera within the Suessiaceae group, the 18S rRNA gene does not have sufficient resolution (Jang et al, 2017b;Raho et al, 2018;Jang et al, 2022). Due to the above, the data were classified as "Ansanella, Asulcocephalium, Biecheleria, Biecheleriopsis, Leiocephalium, Pelagodinium, Piscinoodinium, Polarella, and Yihiella, " and sequences that did not match these genera but belonged to the Suessiaceae family were categorized as "Unidentified. "…”

“…Dinoflagellates (Alveolata: Dinophyceae) are among the most diverse and abundant groups of unicellular protists commonly found in aquatic environments. They are both evolutionarily and ecologically important since they form diverse lineages and have a variety of ecological roles such as primary producers, consumers, mutualists, and parasites; they can also cause harmful algal blooms (Coats, 1999;Jeong et al, 2010;Murray et al, 2016;Suggett et al, 2017;Jang et al, 2022). The dinoflagellate group currently consists of 18 orders, including Suessiales, and more than 2,000 extant species have so far been described (Gómez, 2012;Guiry and Guiry, 2022).…”
