A Glycosylphosphatidylinositol Anchor Is Required for Membrane Localization but Dispensable for Cell Wall Association of Chitin Deacetylase 2 in Cryptococcus neoformans

mBio, 2012
Cell wall proteins (CWPs) mediate important cellular processes in fungi, including adhesion, invasion, biofilm formation, and flocculation. The current model of fungal cell wall organization includes a major class of CWPs covalently bound to β-1,6-glucan

What Are the Functions of Chitin Deacetylases in Aspergillus fumigatus?

Frontiers in Cellular and Infection Microbiology, 2020
Deacetylation of chitin by chitin deacetylases (Cda) results in the formation of chitosan. Chitosan, a polymer of β1,4 linked glucosamine, plays multiple roles in the function of the fungal cell wall, including virulence and evasion of host immune ...

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Differentiation Trajectory of Virus‐Induced Tumour Cells in Rice Revealed by Single‐Cell RNA Sequencing

Plant Biotechnology Journal, Volume 23, Issue 11, Page 4794-4812, November 2025.
ABSTRACT Many plant viruses trigger abnormal differentiation and development of host cells, causing distinct symptoms. Here, in a single‐cell RNA sequence analysis, we find transcriptional heterogeneity between cells from rice leaf sheaths that are infected with rice black streaked dwarf virus (RBSDV) and from those that are virus‐free.

Extraction, Characterization, and Antimicrobial Ability of Chitosan and Edible Oil From Ugandan Winged Termites

Food Science &Nutrition, Volume 13, Issue 10, October 2025.
This study extracted edible oil and chitosan using both chemical and green extraction techniques, from four species of edible winged termites. Yield and efficiency of the extraction techniques were compared, the extracted products characterized for physico‐chemical properties, and the antimicrobial ability of chitosan assessed against a gram‐positive ...
