This study reevaluates Catillariaceae using phylogenetic analysis with enhanced taxon sampling and a six-marker dataset. Findings confirm Catillariaceae as monophyletic, merging Catinariaceae and Leprocaulaceae. New genera and species are described, although challenges persist in key genera. Notably, the genus Placolecis is excluded from Catillariaceae.
This study unveils two new ectomycorrhizal truffle species, Geomorium nahuelbutense and Paragalactinia nothofagacearum, from Nothofagaceae forests in southern South America. These species, derived from separate evolutionary events, highlight distinct distribution patterns tied to their host associations, emphasizing the need for conservation amidst environmental threats.
Coltricia, a genus within Hymenochaetales, plays a vital role in nutrient cycling through its wood-inhabiting nature and ectomycorrhizal associations. Recent surveys in Benin, Guinea, and Togo unveiled two new species, Coltricia langeri and Coltricia mosseboi, identified via morphological and molecular analyses. This discovery expands Africa's Coltricia diversity and underscores the genus's polyphyletic structure.
The study explores how core histones, fundamental protein components of chromatin, affect the antifungal susceptibility of Candida glabrata to echinocandins. It reveals that reduced gene dosage of core histones increases susceptibility, possibly due to heightened reactive oxygen species (ROS) levels. These insights suggest a novel approach to combat echinocandin resistance in C. glabrata by targeting histone proteins.
