Influence of bioprocess variables on the production of extracellular chitinase under submerged fermentation by Streptomyces pratensis strain KLSL55

open access: yesJournal of Genetic Engineering and Biotechnology, 2018
Chitinases are the enzymes which are capable of hydrolyzing chitin to its monomer N-acetyl glucosamine (GlcNac). Present study emphasizes on the impact of critical process variables on the production of chitinase from Streptomyces pratensis strain KLSL55.

Expression of a Serratia marcescens Chitinase Gene in Sinorhizobium fredii USDA191 and Sinorhizobium meliloti RCR2011 Impedes Soybean and Alfalfa Nodulation

open access: yesMolecular Plant-Microbe Interactions, 1999
A gene encoding chitinase from Serratia marcescens BJL200 was cloned into a broad-host-range vector (pRK415) and mobilized into Sinorhizobium fredii USDA191. Chitinolytic activity was detected in S.

Glucanases and Chitinases

open access: yes, 2019
In many yeast and fungi, β-(1,3)-glucan and chitin are essential components of the cell wall, an important structure that surrounds cells and which is responsible for their mechanical protection and necessary for maintaining the cellular shape. In addition, the cell wall is a dynamic structure that needs to be remodelled along with the different phases

Defense heterosis as a novel plant protection strategy: From theory to breeding practice

open access: yesNew Plant Protection, EarlyView.
Defense heterosis, the enhanced disease resistance of hybrids compared to their parents, has evolved from early observations of hybrid vigor to a novel research concept. Advances are now clarifying its diverse genetic and molecular mechanisms across various plant–pathogen interactions.

Factors Associated With Liver Fibrosis in Patients With Type 2 Diabetes and the Predictive Value of CHI3L1

open access: yesPortal Hypertension &Cirrhosis, EarlyView.
In a retrospective cohort of 236 patients with type 2 diabetes (T2DM), metabolic dysfunction‐associated steatotic liver disease (MASLD) was common and significant fibrosis (liver stiffness measurement [LSM] ≥8 kPa) was frequently observed. Serum chitinase‐3‐like protein 1 (CHI3L1) correlated with LSM (r = 0.48) and remained an independent predictor of ...

First genome sequence of a European Alternaria brassicae isolate and genes involved in early development of alternaria leaf spot on Brassica juncea

open access: yesPest Management Science, EarlyView.
This article reports the first genome sequence of a UK Alternaria brassicae isolate. Dual RNA‐sequencing profiling of A. brassicae‐infected Brassica juncea leaves identified differentially expressed genes involved in pathogenicity and host response pathways in moderately resistant Sej‐2 (2) and moderately susceptible Pusa Jaikisan cultivars.

Lecanicillium aphanocladii: a biocontrol agent against insect pests and phytopathogens

open access: yesPest Management Science, EarlyView.
Recent research findings on the biocontrol potential of Lecanicillium aphanocladii fungus against insect‐pests and plant diseases were highlighted. This review indicates that several L. aphanocladii strains show great potential to be developed as multipurpose biocontrol agents active against several insect‐pests, plant diseases and plant parasitic ...
