Summary: This study investigated the phylogeography and genetic diversity of the lichen species Bryoria fuscescens in Europe and western North Africa, revealing Scandinavia as the region with the highest genetic diversity. Three gene pools were identified, with two linked to phenotypic characteristics and the third related to an American sister species. Migration routes were estimated to be from north to south, contradicting glacial refugia distributions. The presence of ancestral shared alleles in distant populations may bias phylogeographic reconstructions.

Summary: Fusarium infections are common in humans and economically important plants, with the Fusarium solani species complex (FSSC) being the most frequent cause in humans. This study analyzed the genotypic and phenotypic characteristics of FSSC isolates from Malaysia and identified eight different species. The taxonomic relationships were resolved phylogenetically, but a more precise MLST scheme is needed for reliable species assignment of FSSC isolates.

Summary: Glioblastoma, a highly lethal brain cancer, has been extensively studied. The mechanism of transformation of tumor-associated macrophages (TAMs) into glioma-associated microglia and macrophages (GAMs) is not well understood. This study found that EFHD2 is enriched in high-grade gliomas and can serve as an independent prognostic factor for overall survival in glioblastoma patients. EFHD2 also regulates the function of macrophages and correlates with immunosuppressive checkpoints.

Summary: The Qinghai-Tibet Plateau is the origin and differentiation site of O. sinensis and its host insects, and the divergence time matches with geological events. This study demonstrates that the EF-1 alpha gene can be used to estimate the divergence time of both O. sinensis and its host insects.

Summary: This study identified a new pathogen, Fusarium buharicum, that causes wilt disease in okra. The pathogen was characterized through morphological and molecular methods, and its growth and reproduction characteristics were studied in different media, temperature, and pH conditions. The study found that potato sucrose agar and potato dextrose agar were the best media for mycelial growth, and 28 degrees C was the optimal temperature for growth and germination. The pathogen only infected okra and was susceptible to the biofungicide Ecohop (Trichoderma atroviride), reducing disease incidence by 93.8% compared to the control.

Summary: Calcium-dependent actin cross-linker EFhD2/Swip-1 is identified as a promoter of rapid actin network reorganization in epithelial wound closure. EFhD2/Swip-1 is highly upregulated in macrophages during metamorphosis and its loss or gain of function affects lamellipodial cell migration. TIRF analyses demonstrate that EFhD2/Swip-1 efficiently cross-links actin filaments in a calcium-dependent manner.

Summary: Fruit rot, caused by Fusarium solani f. sp. cucurbitae, was observed on zucchini fruit in Inner Mongolia, China in August 2021. The disease resulted in corky lesions and internal necrosis of the fruit rind, with an incidence of 10% to 30%. The impact on seed quality and yield in zucchini seed production requires further investigation.

Summary: The highly distinctive Glade of giant species among Antarctic amphipods of the genus Eusirus, named 'crested Eusirus', includes two potential species complexes, the Eusirus perdentatus and Eusirus giganteus complexes, as well as the more distinctive Eusirus propeperdentatus. Molecular phylogenies and statistical parsimony networks were reconstructed, revealing that species diversity of crested Eusirus is underestimated, with DNA-based methods suggesting multiple putative species within the two complexes. The morphological analysis also identified a new species within the E. perdentatus complex, Eusirus pontomedon sp. nov.

Summary: Lichen-derived monoaromatic compounds have bioactive properties such as antioxidant, antifungal, antiviral, cytotoxicity, and enzyme inhibition. This study isolated and identified a series of monoaromatic compounds from lichen and evaluated their α-glucosidase inhibition and antimicrobial activity. Compound 4 showed the strongest α-glucosidase inhibition, while compound 9a exhibited remarkable activity against Staphylococcus aureus.

Summary: A new species, Cryphonectria carpinicola, has been identified as the etiological agent of the European hornbeam decline, distinguishing it from other Cryphonectria species. This study suggests that Cryphonectria has evolved at two evolutionary centers in Europe and Asia Minor, as well as in East Asia.

Summary: Lichens are extensively used in traditional medicine, food, and ethnic practices in the Himalayas and southwestern parts of China, with 142 species used as medicine and 42 species used as food. Understanding the use of lichens in this region is important for comprehending their uses elsewhere and providing a reference for future research on lichen uses.

Summary: This study molecularly characterized a new splipalmivirus (CnSpV1) and a novel fusagravirus (CnFGV1) in Cryphonectria naterciae, shedding light on the molecular and biological properties of these viruses. The tetra-segmented nature of CnSpV1 and its narrow host range restricted to C. naterciae and C. carpinicola were confirmed in this study.

Summary: In this study, PacBio long-read HiFi sequencing was used to characterize the intra-host populations of natural infections of the RNA mycovirus CHV1. The intra-host diversity of CHV1 was shaped by various factors including purifying selection, accumulation of mutations over time, and epistatic interactions within the host genome. Geographical landscape features impacted CHV1 inter-host relationships by restricting dispersal and causing founder effects.

Summary: A novel double-stranded RNA virus, CnFGV1, was characterized from the fungal species Cryphonectria naterciae, with 40% of tested strains being positive for the virus. The virus was able to transmit within-species and cross-species, inducing sectoring and growth reduction in infected strains. This study lays the groundwork for assessing the hypovirulence effect of CnFGV1 against the hornbeam decline in Europe.

Summary: In this study, we identified rare Cryphonectria-like species in our isolate collection from the Balkans using preserved dry mycelium and DNA data. We confirmed the presence of Cryphonectria carpinicola on a Carpinus tree for the first time in the Balkans, and extended the range of Cryphonectria radicalis on Castanea sativa to Bulgaria. The molecular analysis of the oldest specimen, dating back to 1998, confirmed the first reported finding of Cryphonectria radicalis in North Macedonia.

Summary: This study examined the phylogeography genetics and colonization history of the endemic species Lobaria pindarensis in the Himalayas and Hengduan Mountains. It found that the populations originated from the Yunnan region and colonized Bhutan, Nepal, and Xizang areas of the Himalayas. The uplift of the mountains in the late Pliocene and middle Pleistocene influenced the species' distribution pattern.

Summary: Dimelaena tibetica is a new species characterized by a grayish yellow surface, usually with a covering of white pruina, a crustose thallus, areolate at center, radiate-plicate at margin, adnate apothecia and lacking gyrophoric acid. It differs from other usnic acid-containing Dimelaena species by its plane marginal lobes and adnate apothecia. Based on the study of fresh specimens from the environment of the type locality, Dimelaena altissima is proposed as a new combination. The phylogenetic position of the genus Dimelaena was confirmed by generating a sequence from a fresh specimen of Dimelaena oreina. All three species share common characters: usnic acid content and a yellowish green upper surface. Descriptions of these species were based on a combination of morphological and phylogenetic analyses. A key and phylogram are provided for these three Dimelaena species which produce usnic acid.

Summary: This study reports the discovery of Cryphonectria carpinicola fungus in Japan and describes its sexual state on Carpinus species for the first time. Phylogenetic analysis showed that the Japanese and European isolates of C. carpinicola are monophyletic. Further research is needed to investigate the distribution, host range, and life history strategies of this fungus in Japan.
