as defined by its type species is a genus of , and a member of the group known as 'black yeasts and relatives'. has been reported from mutilating human infections such as chromoblastomycosis, disseminated phaeohyphomycosis and mycetoma, while morphologically similar fungi are rather commonly isolated from the environment. Phenotypes are insufficient for correct species identification, and molecular data have revealed significant genetic variation within the complex of species currently identified as or . Multilocus analysis of 118 strains revealed the existence of five reproductively isolated species apparently having different infectious potentials. Strains of the sexual morph cluster within . The newly defined taxa differ markedly in their predilection for the human host.

Article Synopsis
- Distantly related organisms, like cactophilic yeasts, can evolve similar traits and lifestyles to survive in comparable environments, with this study analyzing over 1,000 yeast species to understand their convergent evolution.
- Researchers found that cactophily (association with cacti) evolved independently about 17 times and could be predicted with 76% accuracy using genomic and phenotypic data, with thermotolerance being the most significant factor.
- The study also revealed horizontal gene transfer and duplications in genes related to plant cell wall degradation, indicating that these adaptive traits arose from different molecular pathways, and highlighted a potential link between cactophilic lifestyles and yeast becoming human pathogens.

Microbial infection as a type of environmental risk factors is considered to be associated with long-term increased risk of dementia, including Alzheimer's disease (AD). AD is characterized by two neuropathologically molecular hallmarks of hyperphosphorylated tau and amyloid-β (Aβ), the latter generated by several biochemically reactive enzymes, including γ-secretase. However, how infectious risk factors contribute to pathological development of the AD core molecules remains to be addressed.

Many distantly related organisms have convergently evolved traits and lifestyles that enable them to live in similar ecological environments. However, the extent of phenotypic convergence evolving through the same or distinct genetic trajectories remains an open question. Here, we leverage a comprehensive dataset of genomic and phenotypic data from 1,049 yeast species in the subphylum Saccharomycotina (Kingdom Fungi, Phylum Ascomycota) to explore signatures of convergent evolution in cactophilic yeasts, ecological specialists associated with cacti.

Microplastics (MPs) ubiquitous in environments promote the dissemination of antibiotic resistance genes (ARGs), threatening ecosystem safety and human health. However, quantitative assessments of the health risks of ARGs (HRA) in plastisphere and an in-depth exploration of their driving mechanisms are still lacking. Here, the microbiomes, ARGs, and community assembly processes of five types of MPs in an urbanizing watershed were systematically investigated.
