Dual actions of chloroinconazide on pepper blight in Capsicum annuum: disruption of Phytophthora capsici mycelium and activation of CaCNGC9-mediated SA signaling.

Background: Pepper blight, caused by Phytophthora capsici, is a devastating disease that seriously threatens pepper production worldwide. With the emergence of resistance in P. capsici against conventional fungicides, there is an urgent need to explore novel alternatives for pepper blight management.

Chitin nanocrystals supported copper: a new nanomaterial with high activity with P. syringae pv. Tabaci.

Background: The application of chemical pesticides in control of plant bacterial disease may cause potential environmental pollution. Herein, based on the resistance-inducing ability and the special rod-like structure with high aspect ratio of bio-derived chitin nanocrystals (ChNC), a new Cu composite rod-like nanoparticle was fabricated (ChNC@Cu). The antibacterial activity of the composite nanoparticle was systematically studied, and its safety was evaluated.

Fabrication of CuO nanoparticles composite ε-polylysine-alginate nanogel for high-efficiency management of Alternaria alternate.

Although ε-poly-l-lysine (ε-PL) has a good potential as a green fungicide, high concentration is usually required during its controlling of plant disease. On the other hand, same problems also appeared in the study of CuONP based nano pesticides. In this manuscript, a new composite alginate nanogel (ALGNP) that containing CuONP and ε-PL was fabricated via in situ reduction of CuONP in nanogel and ε-PL surface coating.

Polymorphic Microsatellite Development, Genetic Diversity, Population Differentiation and Sexual State of Phytophthora capsici on Commercial Peppers in Three Provinces of Southwest China.

Pepper blight, caused by the oomycete pathogen Phytophthora capsici (P. capsici), is one of the most destructive soilborne diseases worldwide. Between 2019 and 2020, 235 single spore isolates of P.

Transcriptome analysis reveals the mechanism of zinc ion-mediated plant resistance to TMV in Nicotiana benthamiana.

Zinc ions (Zn) are used to promote plant growth and treat multiple diseases. However, it is still unclear which pathways in plants respond to Zn. In this study, we found that supplying (CHCOO)Zn can effectively delay tobacco mosaic virus (TMV) replication and movement in Nicotiana benthamiana.

Genome-wide analysis of NDR1/HIN1-like genes in pepper ( L.) and functional characterization of under biotic and abiotic stresses.

Plant NDR1/HIN1-like () genes play an important role in triggering plant defenses in response to biotic stresses. In this study, we performed a genome-wide identification of the genes in pepper ( L.) and characterized the functional roles of these genes in response to abiotic stresses and infection by different pathogens.
