Abstract ：
Members of the genus Moelleriella (Hypocreales, Clavicipitaceae) are insect pathogens with specificity for scale insects and whiteflies. However, no mitochondrial genomes are available for these fungi. Here, we assembled seven mitogenomes from M. zhongdongii, M. libera, M. raciborskii, M. gracilispora, M. oxystoma, Moelleriella sp. CGMCC 3.18909, and Moelleriella sp. CGMCC 3.18913, which varied in size from 40.8 to 95.7 Kb. Synteny and codon usage bias was relatively conserved, with the mitochondrial gene arrangement being completely homologous to the gene order of 21 other species within the Hypocreales. Nevertheless, significant intron polymorphism was observed between Moelleriella species. Evolutionary analyses revealed that all 15 core protein-coding genes had ka/ks < 1, indicating purifying selection pressure. Sequence variation within the mitochondrial ATP synthase F0 subunit 6 (atp6) gene showed the largest genetic distance, with the ATP synthase F0 subunit 9 (atp9) gene showing the smallest. Comparative analyses of mitogenomes revealed that introns were the primary factor contributing to the size variation in Moelleriella and, more broadly, within Hypocreales mitogenomes. Phylogenetic analyses indicated that the seven Moelleriella species examined form a well-supported clade, most closely related to Metarhizium. These data present the first mitogenomes from Moelleriella and further advance research into the taxonomy, origin, evolution, and genomics of Moelleriella.

Abstract ：
Introduction Entomopathogenic fungi play a crucial role in the ecological regulation of insect populations and can be exploited as a resource for pest control, sustainable agriculture, and natural products discovery. These fungi and their infected hosts are sometimes highly coveted as part of traditional medicine practices. Here, we sought to examine the biodiversity of entomogenous fungi in subtropical forests of China.Methods Fungal-infected insect specimens were collected from various sites in Fujian Province, China, and purified isolates were obtained through laboratory cultivation and isolation techniques. Molecular characterization of specific target genomic loci was performed on the fungal isolates, and used for phylogenetic analyses using Bayesian inference and maximum likelihood methods to elucidate their taxonomic relationships. Microscopy was used to describe the morphological features of the isolates.Results Through a comprehensive two-year survey of Fujian Province via multilocus molecular phylogenetic analysis targeting the nrSSU, nrLSU, tef1-alpha, rpb1, and rpb2 loci of collected specimens, we identified three novel species within the Clavicipitaceae herein described as: Albacillium fuzhouense sp. nov., Conoideocrella gongyashanensis sp. nov. and Neoaraneomyces wuyishanensis sp. nov., as well as the recently recorded, Metarhizium cicadae. Each new species was also distinguished from its closest relatives by unique morphological characteristics.Discussion These discoveries enrich our understanding of biodiversity within the Clavicipitaceae family and can contribute to the development of new pest control strategies and natural products discovery.

Abstract ：
Neopestalotiopsis and Pseudopestalotiopsis are classified as pestalotioid fungi, include a diverse range of plant pathogenic, endophytic and saprobic species and are widely distributed in tropical and temperate climates. These fungi are associated with a wide variety of plants worldwide and are exemplified by multi-septate conidia with appendages at both ends. Phytopathogenic members cause various plant diseases, for example, leaf spot, fruit rot, canker, blight and various infections affecting palm, mango, blueberry, tea and other important crops. In this study, six isolates were collected from diseased leaves of Litsea verticillata, Ixora chinensis and an unidentified shrub in Fujian Province, China. Based on morphological characteristics and molecular phylogenetic analyses of combined nucleotide sequences of internal transcribed spacer regions of rDNA (ITS), the partial translation elongation factor 1-alpha gene (tef1) and partial beta-tubulin gene (tub2), three new species Neopestalotiopsis litseae sp. nov., Neo. longqishanensis sp. nov. and Pseudopestalotiopsis zhangzhouensis sp. nov. are described and illustrated herein.

Abstract ：
Introduction Bamboo is the largest member of the family Poaceae, and these fast-growing plants have many beneficial ecological effects. Both mutualistic and pathogenic fungi associate with bamboo, however, only a limited number of such fungal species have been identified, and information concerning the diversity of fungi that parasitizes bamboo leaves is sparse.Methods Fungi were isolated from diseased leaves of bamboo from Fujian Province, China. Nucleotide sequences of four genetic loci were used for taxonomic and phylogenetic reconstruction. In addition, the morphological characteristics of fungal structures as well as growth parameters were characterized.Results We report two new fungal species, one each within the Didymosphaeriaceae and Magnaporthaceae, both diverse genera that include saprophytes, endophytes, and pathogens. Based on combined morphological and phylogenetic analyses, including the nucleotide sequences of the internal transcribed spacer (ITS), the 28S large subunit of ribosomal RNA (LSU), the 18S small subunit of nuclear ribosomal RNA gene (SSU), the large subunit of RNA polymerase I (rpb1), and the translation elongation factor 1-alpha gene (tef1-alpha), the two new species described herein have been named as Bifusisporella magnum sp. nov., and Letendraea bambusae sp. nov. Detailed descriptions and morphological features of the species are provided.Discussion These data identify and describe new species within the Didymosphaeriaceae and Magnaporthaceae, expanding the diversity and distribution of fungi associating with bamboo.

Abstract ：
Tomato chlorosis virus (ToCV), first reported in Florida, USA, in 1998, has since emerged in multiple regions worldwide, posing a significant threat to global tomato production. However, its origin, migration patterns, and evolutionary history remain poorly understood. In this study, we used Bayesian phylogeographic analysis of coat protein gene sequences from 155 ToCV isolates to reconstruct its phylogeographic history. Our results show that ToCV evolves at a rate of 6.24 x 10-4 subs/site/year (95% credibility interval: 4.35 x 10-4-8.28 x 10-4), with the most recent common ancestor dating back to 1882. The maximum clade credibility (MCC) tree revealed three major clades, with Clade 1-whose most recent common ancestor dates to approximately 1975-comprising over 90% of the isolates. Although the exact origin of ToCV remains uncertain, we identified five distinct migration pathways: one from Europe to the Americas, one from Europe to South Asia, one from the Middle East to East Asia, one from East Asia to mainland China, and one from mainland China to Europe. These findings underscore the complex global spread of ToCV and suggest that multiple geographic areas have contributed to its ongoing evolution and dissemination.

Abstract ：
Fungal biota represents important constituents of phyllosphere microorganisms. It is taxonomically highly diverse and influences plant physiology, metabolism and health. Members of the order Diaporthales are distributed worldwide and include devastating plant pathogens as well as endophytes and saprophytes. However, many phyllosphere Diaporthales species remain uncharacterized, with studies examining their diversity needed. Here, we report on the identification of several diaporthalean taxa samples collected from diseased leaves of Cinnamomum camphora (Lauraceae), Castanopsis fordii (Fagaceae) and Schima superba (Theaceae) in Fujian province, China. Based on morphological features coupled to multigene phylogenetic analyses of the internal transcribed spacer (ITS) region, the large subunit of nuclear ribosomal RNA (LSU), the partial beta-tubulin (tub2), histone H3 (his3), DNA-directed RNA polymerase II subunit (rpb2), translation elongation factor 1-alpha (tef1) and calmodulin (cal) genes, three new species of Diaporthales are introduced, namely, Diaporthe wuyishanensis, Gnomoniopsis wuyishanensis and Paratubakia schimae. This study contributes to our understanding on the biodiversity of diaporthalean fungi that are inhabitants of the phyllosphere of trees native to Asia.

Abstract ：
建兰花叶病毒（Cymbidium mosaic virus,CymMV）是危害兰花并造成重要经济损失的病毒之一。为揭示CymMV的遗传变异及其适应性进化特征，新测定了16个CymMV石斛兰（Dendrobium nobile）分离物的外壳蛋白基因（coat protein,CP）序列，并结合已报道的52个CymMV中国分离物CP基因序列进行遗传变异及进化分析。遗传多样性分析结果显示，68个CymMV分离物CP基因的核苷酸多样性（P_i）和单倍型多样性（Hd）平均值分别为0.039和0.992，表明该病毒具有较高的遗传多样性。分子变异分析（analysis of molecular variance,AMOVA）显示，CymMV变异源主要来自于病毒个体，约占总变异的71.72%。群体遗传结构分析显示，该病毒可以分为两个大簇（Cluster）,CymMV建兰（Cymbidium ensifolium）分离物独立为一簇（Cluster 1），其他寄主分离物聚为另一大簇（Cluster 2）,Cluster2内相同寄主来源的病毒分离物倾向于相聚成簇。进一步的系统发育与性状关联分析结果显示CymMV与寄主来源存在显著的关联性。上述结果表明，CymMV的遗传变异具有寄主特异性，其适应性进化主要受寄主因素所驱动。

Abstract ：
Bamboo is an economically important crop that has gained prominence as an alternative to wood to reduce deforestation and ecosystem destruction. Diseases of bamboo that typically occur on leaves and stems can cause significant loss, reducing the quality and yield of the bamboo. However, there are few reports identifying the fungal species diversity and potential pathogens of bamboo. Here, we describe four new species of plant fungi from the leaves of bamboo within Fujian provinces, China. Fungi were isolated from diseased leaves collected within Fujian province and identified based on their morphological characteristics and multilocus phylogenies using nucleotide sequences derived from combined datasets of the intervening 5.8S nrRNA gene (ITS), the 28S large subunit of nuclear ribosomal RNA gene (LSU), the large subunit of RNA polymerase I (rpb1), the translation elongation factor 1-alpha gene (tef1-alpha), and the partial beta-tubulin gene (tub2). These analyses helped reveal and clarify taxonomic relationships in the family Magnaporthaceae. The new species of bambusicolous fungi identified include two species of Bifusisporella, described as B. fujianensis sp. nov. and B. bambooensis sp. nov., and two species of Apiospora, described as A. fujianensis sp. nov. and A. fuzhouensis sp. nov. This study further expands the characterization and distribution of fungi associated with bamboo.
