Abstract As a sessile organism, plants have evolved complex and sophisticated immune system to defend against various pathogenic microbes effectively. However, also developed complicated delicate strategies suppress host immunity successfully colonize the host. Dynamic plant‒pathogen interactions require rapid fine-tuned regulation of their gene expression. Increasing evidence has revealed that epigenetic plays key roles in plant defense-related transcriptional reprogramming, as well microbe pathogenicity. In this review, we summarize highlight current progress understanding factors, including DNA/RNA modification, histone chromatin remodeling noncoding RNAs, immunity, phytopathogen pathogenicity interactions. We discuss emerges an efficient strategy for crop breeding disease control.

Plants are challenged by different microbial pathogens that affect their growth and productivity. However, to defend pathogen attack, plants use diverse immune responses, such as pattern-triggered immunity (PTI), effector-triggered (ETI), RNA silencing autophagy, which intricate regulated signaling cascades. Pattern-recognition receptors (PRRs) nucleotide-binding leucine-rich repeat (NLR) the hallmarks of plant innate because they can detect or related immunogenic signals trigger series cascades at cellular compartments. In plants, most commonly, PRRs receptor-like kinases (RLKs) proteins (RLPs) function a first layer inducible defense. this review, we provide an update on how sense pathogens, microbe-associated molecular patterns (PAMPs MAMPs), effectors danger activate responses like PTI ETI. Further, discuss role silencing, systemic acquired resistance versatile host defense response against pathogens.

Abstract RNA interference, or silencing, is an important defence mechanism against viroid infection in plants. Plants encode multiple DICER‐LIKE (DCL) proteins that are key components of the silencing pathway. However, roles different DCLs responses remain unclear. Here, we determined function tomato DCL2b (SlDCL2b) potato spindle tuber (PSTVd) using SlDCL2b loss‐of‐function mutant Compared with wild‐type plants, plants were more susceptible to PSTVd infection, developing severe symptoms earlier and accumulating higher levels RNAs. Moreover, verified feedback for regulation expression by miR6026. Functional blocking miR6026, expressing its target mimics, can enhance resistance These findings deepen current understanding RNAi‐based provide a potentially new strategy control.
