Melanin in Fonsecaea pedrosoi: a trap for oxidative radicals

BMC Microbiology, 2010
Background The pathogenic fungus Fonsecaea pedrosoi constitutively produces the pigment melanin, an important virulence factor in fungi. Melanin is incorporated in the cell wall structure and provides chemical and physical protection for the fungus.

Beta diversity of Arctiinae moths (Lepidoptera: Erebidae) along a recovering tropical forest gradient

Journal of Animal Ecology, EarlyView.
Using novel approaches of Hill‐number based and coverage‐standardized dissimilarity metrics and community‐weighted traits, we show that tiger moth communities exhibit various traits prone to land‐use intensity and undergo a complex and non‐linear response to tropical rainforest recovery, corroborating recent findings on biotic differentiation (Keck et ...

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Hair Degradation Patterns in Aquatic and Soil Environments

Archaeometry, EarlyView.
ABSTRACT Hair is a biological material that can provide information in archaeology and forensics. Previous studies have mainly examined changes occurring post‐mortem. In this study, we focused on hair pulled out ante‐mortem. The aim of the study was to identify patterns in the degradation of hair in water and soil.

Comparative genomics of dark septate endophytes: shedding light on the enigmatic lifestyle and biology of DSEs

New Phytologist, EarlyView.
Ancestral lifestyle reconstruction across the phylogeny of the 107 analysed fungal genomes. Summary Dark septate endophytes (DSE) are widespread root‐colonising fungi with poorly understood lifestyle and ecological functions. We investigated their genomic traits, sexual reproduction signatures, carbohydrate‐active enzyme (CAZyme) and secondary ...

Pinus‐derived membrane vesicles disrupt pathogenic metabolism in fungi

Plant Biology, EarlyView.
Needle‐derived vesicles from pine trees impair fungal metabolism and growth, offering a sustainable strategy to control pine pitch canker disease. Abstract Much of what we know about the biological impacts of vesicles (MVs) is derived from Arabidopsis thaliana.

Tricyclazole alleviates Fonsecaea pedrosoi-induced immune suppression of neutrophils by inhibiting DHN-melanin biosynthesis

Frontiers in Cellular and Infection Microbiology
IntroductionChromoblastomycosis (CBM) is a chronic cutaneous infection caused by dematiaceous fungi, characterized by therapeutic challenges such as difficulty in pathogen clearance and high recurrence rates. Fonsecaea pedrosoi (F.

Biosynthetic Pathways and Regulation of Antibacterial Compounds From Endophytic Fungi: From Chemistry to Genomics and Biotechnology

Chemistry &Biodiversity, Volume 23, Issue 11, November 2026.
Endophytic fungi encode abundant cryptic biosynthetic gene clusters that remain largely silent under conventional cultivation. This review highlights how genome mining, multi‐omics, and cluster activation strategies bridge the BGC‐to‐metabolite gap, enabling the discovery of structurally diverse antibacterial natural products with activity against ...

Nuclear Functional Divergence and Genetic Basis of Cap Colour Variation Revealed by T2T Genomes of Two Compatible Monokaryons in Pholiota adiposa

Microbial Biotechnology, Volume 19, Issue 11, November 2026.
T2T genomes of two compatible monokaryons reveal nuclear functional specialization and identify two candidate loci on chromosomes 6 and 12 associated with red cap colour in the edible mushroom Pholiota adiposa. ABSTRACT Basidiomycete fungi maintain a dikaryotic state throughout their life cycle, in which two genetically distinct haploid nuclei coexist ...

α‐1,3‐Glucan Is Required for Cell Wall Integrity and Full Virulence of Colletotrichum graminicola, but Not for Evasion of PAMP‐Triggered Immunity

Molecular Microbiology, Volume 126, Issue 5, Page 482-502, November 2026.
Abbreviated Summary The role of the major fungal cell wall polymer α‐1,3‐glucan in plant infection is poorly understood. Deletion mutants of the maize anthracnose fungus Colletotrichum graminicola lacking all three α‐1,3‐glucan synthase genes differentiated severely distorted biotrophic hyphae in planta, and virulence was strongly reduced.
