In nature, plant growth and production are adversely affected by plant pathogens. To cope with pathogens, plants evolved a complex defense system that can be classified into two layers: pattern-triggered immunity (PTI) and effector-triggered immunity (ETI). The first layer is activated by the plasma membrane-localized pattern recognition receptors (PRRs) by sensing the conserved microbe-associated molecular patterns (MAMPs) or damage-associated molecular patterns (DAMPs). The second layer is mediated by the intracellular nucleotide-binding site (NBS) leucine-rich repeat (LRR) domain receptors (NLRs) by recognizing some of the pathogen effectors. Both PRRs and NLRs belong to the immune receptors that play important roles in activating and initiating plant immune networks. Although many excellent studies have been performed to demonstrate the function of immune receptors in plant defense, the underlying mechanism by which immune receptors contribute to resistance is still being investigated in current research. Moreover, many novel PRRs and NLRs have been identified and cloned recently. In this case, identifying new pathogen MAMPs and effectors could also be helpful in elucidating the plant–pathogen interaction.
The aim of this research topic is to highlight recent advances in understanding the mechanism of plant defense response activated by immune receptors. New molecular approaches or tools (including omics or multi-omics) to study plant-pathogen interactions are also welcome. The topic accepts original research articles, reviews, and opinions/hypotheses on the following themes but not limited to:
• Identification of novel PRRs/MAMPs and NLRs/effectors.
• Activation mechanism of defense responses to biotic stress by immune receptors.
• Role of proteins downstream of immune receptors in plant defense.
• Dynamic distribution of immune receptors upon pathogen infection.
• Structure and function of PRRs and NLRs.
• Interactions between immune receptors in plant defense.
• The post-translational modification of immune receptors.
• The transcriptional regulation of immune receptors in plant immunity.
• Target and modification of immune receptors by pathogen effectors.
