We report the isolation and characterization of a cDNA-clone for gamma-tubulin from N. crassa. The deduced amino-acid sequence of the cDNA-clone most resembles that of gamma-tubulins from other fungi. Differential Southern blot analysis demonstrates that most probably a single gene represents gamma-tubulin. In addition, Northern blot analysis shows that most probably only one single mRNA encoding gamma-tubulin is transcribed in N. crassa. In a phylogenetic tree that includes all known gamma-tubulins, N. crassa gamma-tubulin is grouped, as expected, together with other fungal gamma-tubulins.

Protein interactors of Spindle Pole Body (SPB) components and septal proteins in fungus : A mass spectrometry-based dataset.
Data Brief

Article Synopsis
- Microtubule Organizing Centers (MTOC) are essential structures in eukaryotic cells for microtubule nucleation, differing in location based on species and cell type.
- The Spindle Pole Body (SPB) functions as the main MTOC in fungi, while other variants, such as the Spitzenkörper, exist but aren't present in all species.
- This study utilized mass spectrometry to analyze proteins interacting with various MTOC components tagged with fluorescent proteins, using a method called Co-IP to capture and identify these proteins.
Genome-Wide Screening and Stability Verification of the Robust Internal Control Genes for RT-qPCR in Filamentous Fungi.

In real-time quantitative PCR (RT-qPCR), internal control genes (ICGs) are crucial for normalization. This study screened 6 novel ICGs: Pre-mRNA-splicing factor cwc15 (); ER associated DnaJ chaperone (); E3 ubiquitin-protein ligase NEDD4 (); ATP-binding cassette, subfamily B (MDR/TAP), member 1 (); Exosome complex exonuclease DIS3/RRP44 (); V-type H-transporting ATPase sub-unit A () from the 22-transcriptome data of 8 filamentous fungi. The six novel ICGs are all involved in the basic biological process of cells and share the different transcription levels from high to low.

γ-Tubulin ring complexes (γ-TuRC) mediate nucleation and anchorage of microtubules (MTs) to microtubule organizing centers (MTOCs). In fungi, the spindle pole body (SPB) is the functional equivalent of the centrosome, which is the main MTOC. In addition, non-centrosomal MTOCs (ncMTOCs) contribute to MT formation in some fungi like Schizosaccharomyces pombe and Aspergillus nidulans.

Institute of Microbiology, Chinese Academy of Sciences, Beijing 100101, China.
Multidrug resistance, defined as the resistance to multiple drugs in different categories, has been an increasing serious problem. Limited antifungal drugs and the rapid emergence of antifungal resistance prompt a thorough understanding of how the occurrence of multidrug resistance develops and which mechanisms are involved. In this study, experimental evolution was performed under single-azole-drug stress with the model filamentous fungus .

Article Synopsis
- Human babesiosis is a rising health concern in China, with a study focusing on identifying Babesia infections in ticks, sheep, and humans in the northeastern region using PCR and genetic sequencing.
- Researchers found a Babesia crassa-like agent in specific tick species and confirmed 31 cases of infection in humans, where common symptoms included headache, nausea, and fever, primarily in previously healthy individuals.
- The findings point to the potential for severe outcomes in immunocompromised patients and the risk of blood supply transmission, highlighting the need for more research on these infections.
