Pectinesterase activity and gene expression correlate with pathogenesis of .

Late blight caused by is the most devastating disease of potato. produces many secondary metabolites and effector proteins, involved in the pathogenesis, which compromise host defense mechanisms. Pectinesterase (PE) is a cell wall degrading enzyme secreted by to infect the host.

A unique Ca-inhibited C-type lectin in shrimp Fenneropenaeuschinensis.

C-type lectins (CTLs) are glycan-binding pattern recognition receptors (PRRs) that can bind to carbohydrates on pathogen surfaces, triggering immune responses in shrimp innate immunity. In this study, a unique Ca-inhibited CTL named FcLec was identified and characterized in Chinese shrimp Fenneropenaeus chinensis. The full-length cDNA sequence of FcLec was 976 bp (GenBank accession number KU361826), with a 615 bp open reading frame (ORF) encoding 204 amino acids.

Characterization and Preliminary Application of a Novel Lytic Bacteriophage vB_VpaP_SJSY21.

is one of the most economically significant aquatic species globally. However, the emergence of acute hepatopancreatic necrosis disease (AHPND) in recent years has resulted in substantial losses within the farming industry. Phage therapy holds promise as an effective strategy for preventing and controlling bacterial infections like AHPND, thereby promoting the healthy and sustainable growth of the shrimp aquaculture sector.

Development and Visualization Improvement for the Rapid Detection of Decapod Iridescent Virus 1 (DIV1) in Based on an Isothermal Recombinase Polymerase Amplification Assay.

Viral diseases have seriously restricted the healthy development of aquaculture, and decapod iridescent virus 1 (DIV1) has led to heavy losses in the global shrimp aquaculture industry. Due to the lack of effective treatment, early detection and regular monitoring are the most effective ways to avoid infection with DIV1. In this study, a novel real-time quantitative recombinase polymerase amplification (qRPA) assay and its instrument-free visualization improvement were described for the rapid detection of DIV1.
