Gapless near Telomer-to-Telomer Assembly of Neurospora intermedia, Aspergillus oryzae, and Trichoderma asperellum from Nanopore Simplex Reads

mycolabadmin

Scientists developed an automated computer workflow that can assemble complete fungal genomes using data from a single type of DNA sequencer. They tested this method on three industrially important fungi and successfully created high-quality, gap-free genome maps for all three. This breakthrough means researchers can now generate high-quality fungal genome sequences faster and more cheaply than before, which will help improve our understanding of these organisms.

Targeted long-read sequencing analysis and antifungal susceptibility profiles of Sporothrix schenckii isolates from Thailand

mycolabadmin

Researchers in Thailand studied a fungal infection called sporotrichosis that affects both cats and people. They used advanced DNA sequencing technology to identify the specific type of fungus and understand how it’s related to similar fungi found in other parts of the world. They also tested how well common antifungal medications work against these fungi and found that some isolates are becoming harder to treat.

What Quality Suffices for Nanopore Metabarcoding? Reconsidering Methodology and Ectomycorrhizae in Decaying Fagus sylvatica Bark as Case Study

mycolabadmin

This study shows that Nanopore DNA sequencing can reliably identify fungi in decaying wood. Researchers developed guidelines for quality filtering of Nanopore data to ensure accurate identification of fungal species. They found that specific mycorrhizal fungi, particularly Laccaria amethystina and Tomentella sublilacina, colonize young beech trees growing on decaying logs and help them obtain nutrients.

Researchers developed a new method to create complete, high-quality genetic maps of fungi using a single affordable sequencing technology from Oxford Nanopore. They created an automated computer program that processes the sequencing data without human intervention and successfully assembled complete genomes for three industrially important fungal species. This breakthrough could make it much easier and cheaper for scientists to study and use fungi for producing medicines, food ingredients, and other useful compounds.

De Novo Genome Assembly and Comparative Genome Analysis of the Novel Human Fungal Pathogen Trichosporon austroamericanum Type-Strain CBS 17435

mycolabadmin

Scientists sequenced the complete genome of a dangerous fungal species called Trichosporon austroamericanum that can cause serious infections in humans, particularly transplant patients. Using advanced long-read sequencing technology, they assembled the organism’s 21 million base pair genome and compared it to a closely related fungal species. The analysis showed this species is genetically distinct and has interesting characteristics that help it survive at higher temperatures than most other fungi. This genetic information will help doctors and researchers better understand and treat infections caused by this emerging pathogenic yeast.
