This study evaluates the theory of island biogeography (TIB) for soil microbes, finding geographic isolation as a main driver of diversity. It reports consistent negative species–isolation relationships across taxonomic groups, indicating dispersal limitation, while positive species–area relationships largely diminish after standardizing sampling, except in arbuscular mycorrhizal fungi.
This proposal advocates for conserving the name Ustilago tritici over U. passerinii and U. ehrenbergiana, crucial for consistent nomenclature in studying smut fungi affecting wheat. The proposal also addresses the typification of Tilletia caries (illegitimately referred to as T. tritici), ensuring clarity in fungal taxonomy and facilitating future research and identification efforts.
In dioecious species, male and female plants exhibit distinct internal microbiomes, influenced by plant sex. This study on four species reveals notable differences: bacterial diversity is higher in males, with Spirochaetota prevalent, while fungi like Albophoma are enriched in females. These findings highlight the crucial role of plant sex in shaping endophyte communities, offering insights for ecological and agricultural applications.
Betaine lipids, such as diacylglyceryl-N,N,N-trimethylhomoserine (DGTS), are non-phosphorus glycerolipids substituting phospholipids under phosphate deficiency. In Basidiomycete fungi, DGTS biosynthesis is non-constitutive and phosphorus-dependent. HPLC-MS/MS lipidomics revealed DGTS differs molecularly from other lipids, showing distinct odd-chain fatty acid enrichment without clear phylogenetic or ecological ties.
