Forskningsöversikt (refereegranskat)abstract
- Recent molecular phylogenetic analyses and morphological Studies have shown that it is necessary to revise the present morphology-based generic delineation of the lichen family Verrucariaceae in order to account for evolutionary relatedness between species. Consequently, several genera were recently described or resurrected, and others were re-circumscribed. As an additional step toward this generic revision, three new genera (Hydropunctaria, Parabagliettoa, Wahlenbergiella) and eleven new combinations are proposed here. A summary of the Current taxonomic and morphological circumscription of all genera investigated so far is also presented. Several monophyletic groups are identified for which further taxonomical changes will be required, but for which taxon and gene sampling is presently viewed as insufficient. Clear morphological synapomorphies were found to be rare for newly delimited genera. In some cases (reduced morphology or plesiomorphism), even the combinations of slightly homoplasious phenotypic characters do not allow a clear morphological generic circumscription. Molecular features are envisioned as characters for delimiting these taxa.

- Three species, Lobothallia brachyloba Paukov & I. V. Frolov, L. epiadelpha Paukov & A. Nordin and L. zogtii Paukov & Davydov, from arid regions of Eurasia (Russia, Kazakhstan, Kyrgyzstan, China and Mongolia) are described as new to science. Lobothallia brachyloba has flat, firmly attached lobes, immersed apothecia lacking a distinct thalline margin, and contains norstictic acid. Both Lobothallia epiadelpha and L. zogtii contain stictic acid and have a brown thallus and sessile apothecia. Lobothallia epiadelpha initially develops on crustose Circinaria spp, has thick lobes loosely attached to the substratum, and brown apothecial discs with constant thalline margins. Lobothallia zogtii is a free-living species with brownish black to jet black apothecial discs surrounded by a receding thalline margin. Lecanora bogdoensis is synonymized with Lobothallia praeradiosa and Lobothallia helanensis is synonymized with L. subdiffracta. Three new combinations, Lobothallia hedinii (H. Magn.) Paukov, A. Nordin & Sohrabi, L. lacteola (Oxner) Senkardesler, Paukov, Davydov & Sohrabi, and L. subdiffracta (H. Magn.) Paukov, are proposed. Phylogenetic analyses of Lobothallia brachyloba, L. epiadelpha and L. subdiffracta (ITS, mtSSU) are presented, showing their relationships within Lobothallia. The lectotype of the name Aspicilia lacteola Oxner is designated. A key to 18 species of Lobothallia is provided.

- In his pioneering work on the genus Aspicilia, Hue (1910) described among others 23 species on a basis of specimens collected by Urbain Jean (Abbé) Faurie in Korea and Japan in 1899–1906. Hue provided his descriptions with carefully made characteristics of thalli as well as measurements of spores and conidia. However Hue’s systematic arrangement of species, which used only anatomical characteristics such as branching of cortical hyphae, form of cells in paraphyses and presence or absence of lateral cortex, gained criticism from Magnusson (1939) for neglecting morphology. Nevertheless, both Hue and Magnusson used very narrow species concept in Aspicilia s.l. (Nordin 2015). Moreover, some species were described on a basis of a single collection and are only known from the type locality. Therefore, critical assessment of Aspicilia species described that time is necessary.

- Aspicilia farinosa sensu auct. (syn. Lecanora farinosa sensu Nyl.) is a species well distinguished from the type of Aspicilia farinosa (Florke) Flagey. Since no valid name is available, it is here described as Lobothallia controversa CI.Roux & A.Nordin, and a detailed description is provided. The new species is closely related to L. chadefaudiana Cl. Roux and has two chemotypes.

- The nomenclature of the Aspicilia anatomy is reconsidered and six species are described. Two of these are new to science (A. calcitrapa and A. prestensis), two are poorly known (A. spermatomanes and A. subdepressa), one is new to Europe (A. brucei), and one is very variable and often confused with other species (A. cinerea). The phylogenetic relationships are assessed by use of PAUP and SplitsTree analyses based on ITS data. In an appendix A. bricconensis discussed.

- Vascular homeostasis is impaired in various diseases thereby contributing to the progression of their underlying pathologies. The endothelial immediate early gene Apolipoprotein L domain-containing 1 (APOLD1) helps to regulate endothelial function. However, its precise role in endothelial cell biology remains unclear. We have localized APOLD1 to endothelial cell contacts and to Weibel-Palade bodies (WPB) where it associates with von Willebrand factor (VWF) tubules. Silencing of APOLD1 in primary human endothelial cells disrupted the cell junction-cytoskeletal interface, thereby altering endothelial permeability accompanied by spontaneous release of WPB contents. This resulted in an increased presence of WPB cargoes, notably VWF and angiopoietin-2 in the extracellular medium. Autophagy flux, previously recognized as an essential mechanism for the regulated release of WPB, was impaired in the absence of APOLD1. In addition, we report APOLD1 as a candidate gene for a novel inherited bleeding disorder across three generations of a large family in which an atypical bleeding diathesis was associated with episodic impaired microcirculation. A dominant heterozygous nonsense APOLD1:p.R49* variant segregated to affected family members. Compromised vascular integrity resulting from an excess of plasma angiopoietin-2, and locally impaired availability of VWF may explain the unusual clinical profile of APOLD1:p.R49* patients. In summary, our findings identify APOLD1 as an important regulator of vascular homeostasis and raise the need to consider testing of endothelial cell function in patients with inherited bleeding disorders without apparent platelet or coagulation defects.
