SUMMARY Late blight, caused by Phytophthora infestans ( P. ), seriously compromises tomato growth and yield. PAMP‐induced peptides (PIPs) are secreted that act as endogenous elicitors, triggering plant immune responses. Our previous research indicated the exogenous application of PIP1 from Solanum pimpinelifolium L3708, named SpPIP1, enhances resistance to . However, little is known about roles additional family members in In addition, there remains a significant gap understanding receptors SpPIPs transcription factors (TFs) regulate signaling defense, combination TFs defending against pathogens rarely studied. This study demonstrates SpPIP‐LIKE1 (SpPIPL1) also strengthens affecting phenylpropanoid biosynthesis pathway. Both SpPIP1 SpPIPL1 trigger defense responses manner dependent on RLK7L. Tomato plants overexpressing precursors (SpprePIP1 SpprePIPL1) exhibited enhanced expression pathogenesis‐related genes, elevated H 2 O ABA levels, increased lignin accumulation. Notably, SpWRKY65 was identified transcriptional activator SpprePIP1 SpprePIPL1 Disease assays gene analyses revealed overexpression (OEWRKY65) confers , while wrky65 knockout led opposite effect. Intriguingly, transgenic studies showed either spraying OEWRKY65 with or co‐overexpressing further augmented resistance, underscoring potential stacking enhancing disease resistance. summary, this offers new perspectives controlling late blight developing varieties improved The results emphasize an eco‐friendly strategy for crop protection, laying theoretical foundation advancing breeding.

Understanding the plant immune system is crucial for using genetics to protect crops from diseases. Plants resist pathogens via a two-tiered innate detection-and-response system. The first Resistance (R) gene was cloned in 1992 . Since then, many cell-surface pattern recognition receptors (PRRs) have been identified, and R genes that encode intracellular nucleotide-binding leucine-rich repeat (NLRs) cloned. Here, we provide list of characterized PRRs NLRs. In addition receptors, components signaling networks were discovered over last 30 years. We review pathways, physiological responses, molecular regulation both PRR- NLR-mediated immunity. Recent studies reinforced importance interactions between two systems. an overview immunity, highlighting challenges perspectives future research.

One of the most important phytohormones is salicylic acid (SA), which essential for regulation plant growth, development, ripening, and defense responses. The role SA in plant–pathogen interactions has attracted a lot attention. Aside from responses, also responding to abiotic stimuli. It been proposed have great potential improving stress resistance major agricultural crops. On other hand, utilization dependent on dosage applied SA, technique application, status plants (e.g., developmental stage acclimation). Here, we reviewed impact saline responses associated molecular pathways, as well recent studies toward understanding hubs crosstalk between SA-induced tolerances biotic stress. We propose that elucidating mechanism SA-specific response various stresses, rhizosphere-specific microbiome modeling, may provide more insights support coping with

Summary Plants face a relentless onslaught from diverse array of pathogens in their natural environment, to which they have evolved myriad strategies that unfold across various temporal scales. Cell surface pattern recognition receptors (PRRs) detect conserved elicitors or endogenous molecules released during pathogen invasion, initiating the first line defence plants, known as pattern‐triggered immunity (PTI), imparts baseline level disease resistance. Inside host cells, effectors are sensed by nucleotide‐binding/leucine‐rich repeat (NLR) receptors, then activate second defence: effector‐triggered (ETI), offering more potent and enduring mechanism. Moreover, PTI ETI collaborate synergistically bolster resistance collectively trigger cascade downstream responses. This article provides comprehensive review plant responses, an overview stepwise activation interactions between PTI‐ETI synergistic signal transduction.

Abstract Cell-surface receptors play pivotal roles in many biological processes, including immunity, development, and reproduction, across diverse organisms. How cell-surface evolve to become specialised different processes remains elusive. To shed light on the immune-specificity of receptors, we analyzed more than 200,000 genes encoding from 350 genomes traced evolutionary origin immune-specific leucine-rich repeat receptor-like proteins (LRR-RLPs) plants. Surprisingly, discovered that motifs crucial for co-receptor interaction LRR-RLPs are closely related those LRR-receptor-like kinase (RLK) subgroup Xb, which perceives phytohormones primarily governs growth development. Functional characterisation further reveals initiate immune responses through their juxtamembrane transmembrane regions, while LRR-RLK-Xb members regulate development cytosolic domains. Our data suggest involved immunity share a common origin. After diversification, ectodomains, juxtamembrane, transmembrane, regions have either diversified or stabilised recognise ligands activate differential downstream responses. work mechanism by plants perceive signals appropriate rapidly changing environment.

Plant stress is one of the most significant factors affecting plant fitness and, consequently, food production. However, may also be profitable since it behaves hormetically; at low doses, stimulates positive traits in crops, such as synthesis specialized metabolites and additional tolerance. The controlled exposure crops to doses stressors therefore called hormesis management, a promising method increase crop productivity quality. Nevertheless, management has severe limitations derived from complexity physiological responses stress. Many technological advances assist science overcoming limitations, which results extensive datasets originating multiple layers defensive response. For that reason, artificial intelligence tools, particularly Machine Learning (ML) Deep (DL), have become crucial for processing interpreting data accurately model genomic variation, gene protein expression, metabolite biosynthesis. In this review, we discuss recent ML DL applications science, focusing on their potential improving development protocols.
