Plant immunity inducers: from discovery to agricultural application

Stress Biology, 2022
While conventional chemical fungicides directly eliminate pathogens, plant immunity inducers activate or prime plant immunity. In recent years, considerable progress has been made in understanding the mechanisms of immune regulation in plants.

Plant NLRs: The Whistleblowers of Plant Immunity

Plant Communications, 2020
The study of plant diseases is almost as old as agriculture itself. Advancements in molecular biology have given us much more insight into the plant immune system and how it detects the many pathogens plants may encounter.

Characterization of the Roles of SGT1/RAR1, EDS1/NDR1, NPR1, and NRC/ADR1/NRG1 in Sw-5b-Mediated Resistance to Tomato Spotted Wilt Virus

Viruses, 2021
The tomato Sw-5b gene confers resistance to tomato spotted wilt virus (TSWV) and encodes a nucleotide-binding leucine-rich repeat (NLR) protein with an N-terminal Solanaceae-specific domain (SD).

Wheat Straw Return Influences Soybean Root-Associated Bacterial and Fungal Microbiota in a Wheat–Soybean Rotation System

Microorganisms, 2022
Roots hold complex microbial communities at the soil–root interface, which can affect plant nutrition, growth, and health. Although the composition of plant microbiomes has been extensively described for various plant species and environments, little is ...

Evaluating Cross-Resistance to Cry and Vip Toxins in Four Strains of Helicoverpa armigera With Different Genetic Mechanisms of Resistance to Bt Toxin Cry1Ac

Frontiers in Microbiology, 2021
Evolution of resistance by pests has diminished the efficacy of transgenic crops producing insecticidal proteins from Bacillus thuringiensis (Bt). In China, where transgenic cotton producing Bt toxin Cry1Ac has been planted since 1997, field control ...

Phytophthora infestans RxLR Effector PITG06478 Hijacks 14-3-3 to Suppress PMA Activity Leading to Necrotrophic Cell Death

Molecular Plant-Microbe Interactions, 2023
Pathogens often induce cell death for their successful proliferation in the host plant. Plasma membrane H+-ATPases (PMAs) are targeted by either pathogens or plant immune receptors in immune response regulation.

GmPAO-mediated polyamine catabolism enhances soybean Phytophthora resistance without growth penalty

Phytopathology Research, 2022
Plant immunity is activated upon perception of pathogens and often affects growth when it is constitutively active. It is still a challenge to balance plant immunity and growth in disease resistance breeding.

Oxicam-type non-steroidal anti-inflammatory drugs inhibit NPR1-mediated salicylic acid pathway

Nature Communications, 2021
The plant defense hormone salicylic acid has structural similarity to oxicam-type non-steroidal antiinflammatories. Here the authors show oxicams, as well as endogenous salicylic acid, can alter cellular redox state and immune signaling without affecting

Type 2 Nep1-Like Proteins from the Biocontrol Oomycete Pythium oligandrum Suppress Phytophthora capsici Infection in Solanaceous Plants

Journal of Fungi, 2021
As a non-pathogenic oomycete, the biocontrol agent Pythium oligandrum is able to control plant diseases through direct mycoparasite activity and boosting plant immune responses. Several P.

New insights into pathogen-mediated modulation of host RNA splicing

Stress Biology, 2022
Alternative splicing (AS) regulation of pre-mRNA has been proven to be one of the fundamental layers of plant immune system. How pathogens disrupt plant AS process to suppress plant immunity by secreted effectors remain poorly understood.
