Summary: The history of the genus Copemetopus has been complicated and plagued with misattributions. Initially classified as a heterotrich, further systematic revisions have revealed that Copemetopus belongs to the subphylum Intramacronucleata. However, its taxonomic status remains uncertain and it is currently considered as incertae sedis. In this study, a new species, Copemetopus mystakophoros, is described in detail, and a new class, Copemetopea, is proposed to accommodate the unique molecular and morphological characteristics of Copemetopus.

Summary: A new species of Penicillium, Penicillium vietnamense, was isolated from Nha Trang Bay, Vietnam in June 2017. It is phylogenetically distinct from its sister species and represents a unique marine fungi species discovered in Vietnam. The data obtained from this study are significant for understanding the taxonomy and geographical distribution of marine fungi in tropical coastal systems like Vietnam.

Summary: The pollen morphology of 20 species from Blumea and Cyathocline Cass. was investigated using a light microscope (LM) and scanning electron microscopy (SEM) to explore their taxonomic significance. Different types of pollen grains were distinguished based on their exine sculpture characters and the number of apertures. Cyathocline was easily distinguished from species of Blumea s. str. based on its smaller size and sparse and longer spines with acute apex. Palynological characteristics indicated that Section Macrophllae and Section Paniculatae of Blumea were not monophyletic groups.

Summary: This article proposes a new method for serial section registration using an unsupervised optical flow network to measure feature similarity and eliminate nonlinear deformation. The optical flow network is also used to estimate and compensate for cumulative registration error, enabling the reconstruction of biological tissue structures. Experimental results demonstrate that this method effectively improves the spatial continuity of serial sections and enhances the accuracy of registration and reconstruction for biological tissue structures.

Summary: This study utilized scanning electron microscopy to describe the microtrichia of labral fan primary rays and the posterior proleg hooks in 14 Neotropical black fly species for the first time. It found four patterns of microtrichia and two types of hooks barbs disposition, suggesting that posterior proleg hooks barbs are common among black fly species and not related to larval habitat or microtrichial patterns. Additionally, it indicated that flow conditions may influence the microtrichial patterns of last-instar larvae in most Neotropical species studied.

Summary: This study examines the roles of two saprophytic fungi in soil aggregation and finds that they can effectively promote the formation of macroaggregates and the accumulation of organic carbon and nitrogen. Compared to microbial communities, fungi of the same or similar species are more conducive to mutual attraction and linkage between hyphae, which more strongly promote soil aggregation.

Summary: The morphology of stigma in the family Asteraceae has taxonomic significance. In this study, the morphological characteristics of stigma in 28 genera, 32 species, and two varieties of Asteraceae were observed using scanning electron microscopy. The results revealed the existence of 10 types of stigma morphology, including eight types that were reported for the first time. The morphological characteristics of stigma supported the relationships between genera Aster and Erigeron, as well as among genera Sonchus, Taraxacum, and Youngia. This study expanded the diversity data of stigma types and provided a morphological basis for the phylogenetic evolution study of Asteraceae.

Summary: This study investigates the kinetics and morphology of bacterial cellulose production by Leifsonia soli. The cellulose layer formation was observed to increase until the 7th day of incubation. X-ray diffraction analysis confirmed the semi crystalline nature of cellulose and identified its structure as allomorphs of I alpha and I beta. The study provides insights into the mechanism of cellulose formation and predicts the maximum cellulose synthesis.

Summary: This study used scanning electron microscopy to investigate the ultrastructure of macrophages in different regions of the cochlea and analyzed their phagocytic activities and immune molecule expression. The results showed that basal macrophages exhibited greater phagocytic activities in aging and noise-induced damage. Differences in the expression of immune molecules were also observed between the apical and basal cochlear tissues of young mice. Additionally, the study found that macrophages in the apical and basal regions undergo a transformation in their morphologies as the cochlea ages.

Summary: Fusarium fujikuroi, the pathogen of rice bakanae disease, can be subclassified into two groups: gibberellin (G) and fumonisin (F). Thiophanate-methyl (TM), a benzimidazole fungicide, has been widely used to control F. fujikuroi. In Japan, it was found that F-group strains are TM sensitive (TMS), while most G-group strains are TM resistant (TMR). The TMR strains have mutations E198K and F200Y in beta(2)-tubulin. A diagnostic method using loop-mediated isothermal amplification with fluorescent loop primers was developed and applied to identify these mutations in 37 TMR strains and 56 TMS strains. The results showed that 100% of the TMR strains had either the E198K mutation (41%) or the F200Y mutation (59%), while none of the TMS strains had these mutations. Interestingly, a TMR strain in the F group with an F200Y mutation was discovered. These findings suggest that the E198K and F200Y mutations in beta(2)-tubulin contribute to TM resistance in F. fujikuroi.

Summary: This study investigated the EcM fungal spore bank communities in soil in remnant patches of Japanese Douglas-fir forest. The results showed that these spore banks were not restricted to Douglas-fir forests and extended to surrounding forest dominated by arbuscular mycorrhizal trees. The community structure of EcM fungal spore banks differed significantly between study sites but not between forest types.

Summary: The purpose of this study was to investigate why the cation exchange capacity (CEC) was not enhanced in low acid buffering capacity (ABC) soils despite higher fine-root biomass and total carbon (TC) content. The results showed that increased SOM degradation in the low ABC soils prevented the increase in carboxyl group content in the stabilized SOM fraction, leading to no increase in CEC.
