A polysaccharide deacetylase from Puccinia striiformis f. sp. tritici is an important pathogenicity gene that suppresses plant immunity

Plant Biotechnology Journal, Volume 18, Issue 8, Page 1830-1842, August 2020., 2020
Summary The cell wall of filamentous fungi, comprised of chitin, polysaccharide and glycoproteins, maintains the integrity of hyphae and protect them from defence responses by potential host plants. Here, we report that one polysaccharide deacetylase of Puccinia striiformis f. sp.

Structure and function of a broad-specificity chitin deacetylase from Aspergillus nidulans FGSC A4

Scientific Reports, 2017
Enzymatic conversion of chitin, a β-1,4 linked polymer of N-acetylglucosamine, is of major interest in areas varying from the biorefining of chitin-rich waste streams to understanding how medically relevant fungi remodel their chitin-containing cell ...

Rim Pathway-Mediated Alterations in the Fungal Cell Wall Influence Immune Recognition and Inflammation

mBio, 2017
Compared to other fungal pathogens, Cryptococcus neoformans is particularly adept at avoiding detection by innate immune cells. To explore fungal cellular features involved in immune avoidance, we characterized cell surface changes of the C.

Plant species‐specific recognition of long and short β‐1,3‐linked glucans is mediated by different receptor systems

The Plant Journal, Volume 102, Issue 6, Page 1142-1156, June 2020., 2020
Summary Plants survey their environment for the presence of potentially harmful or beneficial microbes. During colonization, cell surface receptors perceive microbe‐derived or modified‐self ligands and initiate appropriate responses. The recognition of fungal chitin oligomers and the subsequent activation of plant immunity are well described.

Rational protein design of Bacillus sp. MN chitosanase for altered substrate binding and production of specific chitosan oligomers

Journal of Biological Engineering, 2019
Background Partially acetylated chito-oligosaccharides (paCOS) have a variety of potential applications in different fields, but to harness their benefits, pure paCOS or well-defined paCOS mixtures are essential.

Microbial Valorization of Chitinous Bioresources for Chitin Extraction and Production of Chito-Oligomers and N-Acetylglucosamine: Trends, Perspectives and Prospects

, 2018
Chitin, the crystalline polymer of N-acetylglucosamine (GlcNAc) is the world’s second most abundant carbohydrate and principal structural component of cell wall of fungi, yeasts and algae, insect exoskeletons, shells of crustaceans and the microfilarial sheath of nematodes. GlcNAc is present in peptidoglycan, hyaluronic acid and keratin sulfate.

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

Mass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Examining the interplay between Streptococcus agalactiae, the biopolymer chitin and its derivative

MicrobiologyOpen, Volume 8, Issue 5, May 2019., 2019
Chitosan at concentrations of 0.2% or higher, inhibits the growth of S. agalactiae. However, lower than inhibitory level of chitosan stimulates the growth of the bacterium. Abstract Streptococcus agalactiae is a highly pathogenic bacterium of aquatic species and terrestrial animals worldwide, whereas chitin and its derivative chitosan are among the ...

A journey into the world of small RNAs in the arbuscular mycorrhizal symbiosis

New Phytologist, Volume 242, Issue 4, Page 1534-1544, May 2024.
Summary Arbuscular mycorrhizal (AM) symbiosis is a mutualistic interaction between fungi and most land plants that is underpinned by a bidirectional exchange of nutrients. AM development is a tightly regulated process that encompasses molecular communication for reciprocal recognition, fungal accommodation in root tissues and activation of symbiotic ...
