Comparing signaling mechanisms engaged in pattern-triggered and effector-triggered immunity.

Current Opinion in Plant Biology, 2010
Plants employ two modes of their innate immune system to resist pathogen infection. The first mode of immunity is referred to as pattern-triggered immunity (PTI) that is triggered by molecular patterns common to many types of microbes. The second mode is triggered by recognition of pathogen effectors and is called as effector-triggered immunity (ETI ...

XYLEM CYSTEINE PEPTIDASE 1 and its inhibitor CYSTATIN 6 regulate pattern-triggered immunity by modulating the stability of the NADPH oxidase RBOHD.

The Plant Cell, 2023
Plants produce a burst of reactive oxygen species (ROS) after pathogen infection to successfully activate immune responses. During pattern-triggered immunity (PTI), ROS are primarily generated by the NADPH oxidase RESPIRATORY BURST OXIDASE HOMOLOG D ...

NLRs guard metabolism to coordinate pattern- and effector-triggered immunity

Nature, 2021
Pattern-triggered immunity (PTI) and effector-triggered immunity (ETI) in plants enable them to respond to pathogens by activating the production of defence metabolites that orchestrate immune responses1-4. How the production of defence metabolites is promoted by immune receptors and coordinated with broad-spectrum resistance remains elusive.

The study of pattern-triggered immunity in Arabidopsis

Canadian Journal of Plant Pathology, 2017
AbstractThe initial stage of plant defence against pathogen challenge is dependent on the perception of microbe-associated molecular patterns (MAMPs) by cognate pattern recognition receptors (PRRs), leading to a basal plant immune response referred to as pattern-triggered immunity (PTI).

Engineering plant leucine rich repeat-receptors for enhanced pattern-triggered immunity (PTI) and effector-triggered immunity (ETI)

2020
This chapter presents the cutting-edge knowledge on the immune mechanisms of plants in responding to microbial pathogens: bacteria, fungi, oomycetes and viruses. In the wide range of mechanisms of plant immunity, several approaches to enhance or alter the resistance conferred by PTI and ETI have been tested in various laboratories, such as transfer of ...

Repression of pattern-triggered immune responses by hypoxia in Arabidopsis

2023
AbstractBiotic and abiotic stresses frequently co-occur in nature, yet, relatively little is known about how plants co-ordinate the response to combined stresses. Previous research has shown that protein degradation by the ubiquitin/proteasome system is central to the regulation of multiple independent stress response pathways in plants.

The GSK3/Shaggy-Like Kinase ASKα Contributes to Pattern-Triggered Immunity.

Plant physiology, 2016
The first layer of immunity against pathogenic microbes relies on the detection of conserved pathogen-associated molecular patterns (PAMPs) that are recognized by pattern recognition receptors (PRRs) to activate pattern-triggered immunity (PTI). Despite the increasing knowledge of early PTI signaling mediated by PRRs and their associated proteins, many

Current understanding of pattern-triggered immunity and hormone-mediated defense in rice (Oryza sativa) in response to Magnaporthe oryzae infection.

Seminars in Cell and Developmental Biology, 2018
Plant pathogens represent a huge threat to world food security, affecting both crop production and quality. Although significant progress has been made in improving plant immunity by expressing key, defense-related genes and proteins from different ...

Cell cycle regulation under pattern-triggered immunity

In a world with a constantly growing population, improving crop yields is necessary to ensure food security. However, plant diseases severely impact crop yields, and breeding efforts to enhance plant immunity can be limited by trade-offs between immune activation and growth.

OsWRKY7 contributes to pattern-triggered immunity against Xanthomonas oryzae pv. oryzae

Biochemical and Biophysical Research Communications
Rice is a staple crop continually threatened by bacterial and fungal pathogens. OsWRKY transcription factors are involved in various disease responses. However, the functions of many OsWRKYs are still elusive. In this study, we demonstrated that OsWRKY7 enhances rice immunity against Xanthomonas oryzae pv. oryzae (Xoo). OsWRKY7 localized in the nucleus,
