Neowestiellopsis gen. nov, a new genus of true branched cyanobacteria with the description of Neowestiellopsis persica sp. nov. and Neowestiellopsis bilateralis sp. nov., isolated from Iran

Description of novel species of Aliinostoc, Desikacharya and Desmonostoc using a polyphasic approach

“…Through this study we report the first evidence of members of the genera Aliinostoc, Desmonostoc and Desikacharya from Iran. The present study along with our previous study [22] demonstrates the need to further explore the cyanobacterial diversity of Iran. We anticipate that many more novel taxa of cyanobacteria from Iran may be described in the future.…”

“…The unique geographical location and favourable climatic conditions along with almost no reports of cyanobacterial taxa make Mazandaran province one of the interesting locations to study cyanobacterial diversity. This is evident from our previous work, in which we described a novel genus of true branching cyanobacteria; Neowestiellopsis also isolated from the Mazandaran province of Iran [22].…”

When will taxonomic saturation be achieved? A case study in Nunduva and Kyrtuthrix (Rivulariaceae, Cyanobacteria)

“…The 94.5% threshold for separating genera is not achieved in many to most Rivulariaceae, Aphanizomenonaceae, Nostocaceae, or Hapalosiphonaceae. We made new threshold comparisons among Hapalosiphonaceae, which has several new genera based on recent papers (Miscoe et al 2016, Kabirnataj et al 2018, Casamatta et al 2020 and found that in that family, all eight genera recognized have average genetic identities among genera >94.5% (Table S5). It is very clear that 16S rRNA genetic identities are often uninformative at both the species and genus levels in Nostocales, and this is especially true for both Nunduva and Kyrtuthrix.…”

“…In most instances, when new genera have been described, they contain only a single new species (Casamatta et al 2006, Joosten 2006, Fiore et al 2007, Reh akov a et al 2007, Lamprinou et al 2011, 2012, Novis and Visnovsky 2011, Dadheech et al 2012, Thu et al 2012, Zammit et al 2012, Nguyen et al 2013, Ha sler et al 2014, Wilde et al 2014, Dvo rak et al 2015, Song et al 2015, Vaz et al 2015, Alvarenga et al 2016, Jahod arov a et al 2017, Sciuto et al 2017, Cai et al 2018a,b, 2019, 2020a,b,c, Zhou et al 2018, and many more). Multiple species have sometimes been described with the description of a new genus (Engene et al 2012, Gonz alez-Resendiz et al 2018a, Kabirnataj et al 2018, Mai et al 2018, Saraf et al 2018a, 2019a, Pietrasiak et al 2019, 2021, but it has been more common to have multiple species in a new genus consisting of multiple new combinations as a result of revision of polyphyletic genera (e.g., Wacklin et al 2009, Zapom elov a et al 2010, Zapom elov a et al 2012, Struneck y et al 2017. In a number of instances, after the initial description of a new genus, more species have been discovered in the genus once it has molecular definition.…”

Algal Toxic Compounds and Their Aeroterrestrial, Airborne and other Extremophilic Producers with Attention to Soil and Plant Contamination: A Review

“…Other newly described terrestrial cyanoprokaryotes, isolated from dried paddy fields of Mazandaran (Iran), Neowestiellopsis, with two species N. persica and N. bilateralis were supposed to be cryptic taxa of true-branching cyanoprokaryotes [212]. Considering that the phylogenetically close Westiellopsis prolifica has been shown as producer of toxic antibacterial westiellamide (a bistratamide-related cyclic peptide) in soils and MCs in freshwaters [66,213], it is possible to speculate similar toxigenic abilities in the aeroterrestrial Neowestiellopsis.…”
