A DNA barcoding approach based on ITS sequences shows that these two groups comprise more species and phylogenetic diversity than previously known. Specimens identified as B. vernalis, the type species of the genus, appear to be paraphyletic with regard to B. chrysantha. In addition, there is a morphologically similar species belonging to the B. meiocarpa-group and tentatively named “B. orientalis” in previous publications. Biatora subduplex has for some time been known to comprise specimens from the B. vernalis-, as well as the B. meiocarpa-group. Similar to the situation in B. vernalis, samples from the meiocarpa-clade form several subclades close to B. meiocarpa. Anatomical studies reveal subtle, but recognizable morphological differences between B. subduplex s.str. and the species in the meiocarpa-clade, but not between the subclades. Here, we describe Biatora orientalis as new to science, raise B. meiocarpa var. tacomensis to species rank and provide revised identification keys for the B. vernalis- and B. meiocarpa-groups.","PeriodicalId":52151,"journal":{"name":"Plant and Fungal Systematics","volume":"9 39","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139147458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, the advancement in molecular genetics technology has given rise to the molecular method for plant identification and elucidation. One hundred twenty-five (125) gene sequences of Vanda species from the Philippines were obtained from the NCBI GenBank. Four of the 25 loci were further examined using MEGA 11 software for multiple sequence alignment, sequence analysis, and phylogenetic reconstruction. The indel-based and tree-based methods were combined to compute the species resolution. The result showed that ITS from the nuclear region obtained the highest species resolution with 66.67%. It was then followed by psbA-trnH, matK, and trnL-trnF from the chloroplast genome with a species resolution of 60%, 40%, and 30.77%, respectively. ITS and psbA-trnH satisfied the ideal length for DNA barcoding as they have 655 bp and 701 bp, respectively. The locus psbA-trnH was also considered to have a higher potential to discriminate Vanda species since only a few sequences were tested for ITS. Furthermore, ITS and trnL-trnF have the highest variable rate, which is 2.9%, while matK and psbA-trnH have 2% and 1.3%, respectively. This showed the nature of the unique sequences of various species. In this study, the indel-based method provided better results than the tree-based method. It will help support further DNA barcoding studies and strengthen the conservation and protection of Vanda spp. in the Philippines.","PeriodicalId":52151,"journal":{"name":"Plant and Fungal Systematics","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46251587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Gorce Mts flora of the order Desmidiales comprises 20 genera and 247 species. The most diverse genera in the Gorce Mts are Cosmarium with 99 taxa, Closterium with 39 taxa, Staurastrum with 38 taxa and Euastrum with 17 taxa. All reported taxa are described and documented by original hand drawings and microphotographs. Environmental data with geographical coordinates are included for all studied sites. Among the recorded taxa, eight (Actinotaenium borgeanum, Actinotaenium gelidum, Actinotaenium perminutum, Cosmarium alpestre, Cosmarium dispersum, Cosmarium paragranatoides, Closterium sublaterale, Staurastrum pyramidatum) are new for the Polish flora. An important factor affecting the biodiversity of desmids in the Gorce area is human activity. In typically anthropogenic habitats, which in the study area include roads and paths, 157 species were found (63.7% of the Gorce desmid flora). Many montane species, such as Closterium pusillum and Cosmarium decedens, associated with wet moss on rocks, had secondary habitats there. A group of 21 species found only in anthropogenic habitats can be considered anthropophytes of the studied area. There are also semi-natural habitats in the form of meadows that persist only due to human activity. The situation is similar to that of vascular plants. Clearings used until the 1980s showed significantly higher species richness than clearings where grazing has been abandoned for a long time. Overall, human activity has contributed to an increase of desmid species diversity in the Gorce region.","PeriodicalId":52151,"journal":{"name":"Plant and Fungal Systematics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42101849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Endolithic metacommunities comprise all major groups of microorganisms, such as chemo-organotrophic, chemo-lithotrophic and phototrophic, represented by bacteria, microalgae and microfungi. Their diversity is often difficult to describe and may remain underestimated. Furthermore, knowledge about the diversity of microorganisms colonizing rocks in peculiar niches is even poorer due to the difficulty to retrieve environmental specimens. Here, we report the phylogenetic and phenotypic characterization of a few endolithic fungi and algae isolated from rock fragments collected at high elevation, i.e., on the top of two mountains over 6000 m altitude, Muztagh Ata (China) and Cerro Mercendario (Argentina). The identity of the strains was confirmed by sequencing the nuclear ITS and LSU, the plastidial rbcL loci and by morphological analysis. Three fungal strains belonging to the class Dothideomycetes and one algal strain belonging to the genus Trebouxia were isolated from Muztagh Ata, while six fungal strains belonging to the order Chaetothyriales and four algal strains belonging to the genus Myrmecia were isolated from Cerro Mercedario. The detected species diversity is discussed in an evolutionary and ecological context.","PeriodicalId":52151,"journal":{"name":"Plant and Fungal Systematics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46519191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
