RNA interference in crop protection: opportunities and challenges during the transition to commercialization

open access: yesPest Management Science, Volume 82, Issue 7, Page 5971-5986, July 2026.
RNA interference (RNAi) technologies, host‐induced gene silencing (HIGS) and spray‐induced gene silencing (SIGS), potentially offer sustainable crop protection. However, efficacy, costs, regulatory clarity, and socio‐environmental impacts require further evaluation for broader use.

The Chitin Connection

open access: yesmBio, 2012
Chitin, a polymer of N-acetylglucosamine, is an essential component of the fungal cell wall. Chitosan, a deacetylated form of chitin, is also important in maintaining cell wall integrity and is essential for Cryptococcus neoformans virulence.

Wheat's war against stripe rust: Integrating host immunity, genomics and breeding for durable resistance

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Wheat (Triticum aestivum L.), a foundation of global food security, faces persistent threats from stripe rust caused by Puccinia striiformis f. sp. tritici (Pst). The pathogen thrives in cool and humid environments and regularly causes epidemics that lead to severe yield losses.

Perspectives of Chitin Deacetylase Research

open access: yes, 2011
Chitin and chitosan are copolymers of N-acetyl-D-glucosamine (GlcNAc) and D-glucosamine (GlcN) units linked with β-(1-4) glycosidic bond, where the predominant units are GlcNAc for chitin or GlcN for chitosan in their polymeric chains (Fig. 1).

Host‐Induced Silencing of Rhizoctonia Solani 5‐Enolpyruvylshikimate‐3‐Phosphate Synthase Impairs Its Virulence in Rice

open access: yesPlant Biotechnology Journal, Volume 24, Issue 6, Page 3573-3593, June 2026.
ABSTRACT Sheath blight disease of rice caused by the fungal pathogen R. solani AG1‐IA remains a big threat to rice production worldwide. A limited genetic variation in rice for tolerance to this pathogen and little success in understanding how it defeats host defence are major reasons behind it.

The influence of chitin structure on its enzymatic deacetylation

open access: yesChemical and Process Engineering, 2016
The possibility of producing chitosan by enzymatic deacetylation of chitin has been the subject of numerous investigations over the last twenty years, but to date no satisfactory method has been developed.

A Conserved Magnaporthe oryzae Effector Counteracts the Rice Ubiquitin‐Proteasome System by Disrupting the E2 Function to Suppress Immunity

open access: yesPlant Biotechnology Journal, Volume 24, Issue 6, Page 4302-4316, June 2026.
ABSTRACT Pathogens commonly secrete effectors into host cells to facilitate invasion. In the host ubiquitin‐proteasome system (UPS), E3 ubiquitin ligases often target pathogen effectors for degradation, thereby enhancing immune responses. In turn, pathogen effectors frequently disrupt E3 ligase function to promote virulence. However, it remains largely

Bioconversion of chitin to chitosan: purification and characterization of chitin deacetylase from Mucor rouxii. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1993
Chitin deacetylase, the enzyme that catalyzes the hydrolysis of acetamido groups of N-acetylglucosamine in chitin, has been purified to homogeneity from mycelial extracts of the fungus Mucor rouxii and further characterized. The enzyme exhibits a low pI (approximately 3).

Acetylation Activity and Specificity of Peptidoglycan Deacetylase BsPdaC Acting in Reverse on Chitooligosaccharides

open access: yesChemCatChem, Volume 18, Issue 10, 27 May 2026.
Bacillus subtilis PdaC is the first peptidoglycan deacetylase able to act in reverse, acetylating a glucosamine oligomer (chitopentaose) with a pattern of acetylation mirroring the natural deacetylation reaction with unique final regioselectivity, acetylating all but the reducing end of D5.
