Summary: The study presents FUSARIUM-ID v.3.0, a database designed for the identification of Fusarium species using sequences of multiple phylogenetically informative loci. The version includes improvements in metadata annotation, taxon representation, sequence database availability, and tutorial files for local BLAST searches. FUSARIUM-ID will be regularly updated with newly identified species and more in-depth sampling of recognized species.

Summary: Tabebuia rosea, an economically important tree in Mexico, was found to be infected by F. pseudocircinatum causing floral malformation. The study identified the causal agent, analyzed its relationship to Fusarium spp. from another tree species, and examined mycotoxin production and mating type idiomorphs of the fungus recovered from T. rosea and Swietenia macrophylla.

Summary: Accurate species-level identification of Fusarium is essential for disease diagnosis and management. However, there are challenges in identifying Fusarium due to the large number of phylogenetically distinct species, many of which are not formally described, and the limitations of morphology-based identification. To address this, research groups are working on populating databases with informative genes that can accurately identify Fusarium species and outlining best practices for DNA sequence-based identification.

Summary: The study identified various Fusarium species from understory vegetation in mango orchards with mango malformation disease (MMD) in Mexico, indicating herbaceous hosts can harbor Fusarium causing MMD. This is the first report of such hosts in Mexico and the information provided will be valuable for further study on the role of weeds in the epidemiology of MMD and disease management.

Summary: Guarana cultivation in the Brazilian Amazon is hampered by the disease caused by Fusarium decemcellulare, leading to significant yield losses. This study examined the genetic diversity and population structure of F. decemcellulare isolates from eight guarana production areas. The results revealed moderate gene diversity but high genotypic diversity. Two major populations (C1 and C2) were identified, with most of the genetic diversity found within these populations. Sexual reproduction was also observed in F. decemcellulare. Human-mediated movement of seedlings may have influenced the genetic structure of this pathogen.

Summary: Stem cankers and twig dieback were observed as the most serious diseases in fig and loquat trees in Iranian fruit tree orchards. A new taxon, Stilbocrea banihashemiana sp. nov., was identified based on phylogenetic analysis and morphological observations. This novel pathogen was found to induce stem cankers, wood discoloration, and twig dieback, and may have a wide host range.

Summary: Through phylogenetic analyses of mouthless ciliates, it was found that astomy evolved independently at least three times, ranging from the Paleozoic to the Cenozoic period. Mouthless endosymbionts inhabiting mollusks, planarians, and annelids exhibit morphological differences and do not cluster together.

Summary: In this study, DNA sequencing was used to identify and characterize 290 Fusarium strains isolated from root-colonizing endophytic fungi in northern Kazakhstan. A total of 16 different Fusarium species were identified, including eight known species, four novel species, and a phylogenetically divergent lineage F. steppicola. New species were described based on molecular phylogenetic and morphological analyses.

Summary: Twelve new species of Inocybe are described and compared with 24 type specimens. Detailed morphological and molecular investigation was conducted to describe these species. The study also confirmed synonymy relationships between some species. Lastly, all new species were supported by phylogenetic analyses.

Summary: This study investigates the evolutionary relationships and species diversity within the Fusarium buharicum species complex (FBSC), as well as the potential of these species to produce mycotoxins and other bioactive secondary metabolites. The findings support the recognition of seven genetically distinct species within the FBSC, with three newly discovered species. Some of these species are phytopathogenic, while others have been found in human blood or soil. The study also analyzes the potential of FBSC isolates to produce mycotoxins, pigments, and phytohormones.

Summary: Ray-finned fishes (Actinopterygii) are the most diverse group of vertebrates, with phylogenetic relationships historically studied through morphology and more recently through genomic analyses. This study demonstrates the utility of collagen type I amino acid sequences for phylogenetic estimation of ray-finned fishes, showing high congruence with genomic studies but limited congruence within the Percomorpha. The research provides important insights for future phylogenetic analyses of extinct actinopterygian species using collagen (I) sequencing.

Summary: This study conducted a phylogenetic analysis of Oxalis subg. Thamnoxys and its sections. The results showed that Oxalis subg. Thamnoxys was monophyletic only when O. praetexta was transferred to Oxalis subg. Oxalis. This study provides new insights and updated classification criteria for the subgenus, and is important for understanding its morphological diversity and biogeographic history in South America.

Summary: The emergence of variants of concern (VOCs) in the ongoing SARS-CoV-2 pandemic can be attributed to an episodic increase in the substitution rate of the virus, which is around 4 times higher than the background rate estimate. This increase in substitution rate may have lasted for several weeks or months.
