Rice (Oryza sativa) is a crucial staple crop for global food security, particularly in Asia. However, rice production faces significant challenges from various diseases that can cause substantial yield losses. This review explores the role of genetic resistance disease management, focusing on molecular mechanisms underlying plant–pathogen interactions and strategies developing resistant varieties. The paper discusses qualitative quantitative resistance, emphasizing importance (R) genes, defense-regulator trait loci (QTLs) conferring broad-spectrum resistance. Gene-for-gene relationships rice–pathogen are examined, Xanthomonas oryzae pv. Magnaporthe oryzae. also covers recent advancements breeding techniques, including marker-assisted selection, engineering, genome editing technologies like CRISPR-Cas. These approaches offer promising avenues enhancing while maintaining potential. Understanding exploiting durable disease-resistant varieties, essential ensuring sustainable security face evolving pathogen threats changing environmental conditions.

Abstract In reaction to a stimulus, signaling molecules are made, generate response, and then degraded. Nucleotides classically associated with central metabolism nucleic acid biosynthesis, but there number of nucleotides nucleotide derivatives in plants which this simple definition molecule applies whole or at least part. These include cytokinins chloroplast guanosine tetraposphate (ppGpp), as well extracellular canonical such ATP (eATP) NAD+ (eNAD+). addition, is series compounds derived from ADP ribose (ADPR), ATP–ADPR dinucleotides their hydrolysis products (e.g. pRib-AMP) together different variants cyclic ADPR (cADPR, 2´-cADPR, 3´-cADPR), also 3´,5´-cAMP 2´,3´-cyclic nucleoside monophosphates. Interestingly, some these have recently been shown play role pathogen defense. review, we highlight exciting new developments. We review that considered candidates for molecules, example purine deoxynucleosides, discuss more controversial cases.

In Arabidopsis thaliana, the POWDERY MILDEW RESISTANT4 (PMR4)/GLUCAN SYNTHASE LIKE5 (GSL5) callose synthase is required for pathogen-induced deposition in cell wall defense. Paradoxically, pmr4/gsl5 mutants exhibit strong resistance to both powdery and downy mildew. The mildew of has been attributed upregulated salicylic acid (SA) signaling based on its dependance PHYTOALEXIN DEFICIENT4 (PAD4), which controls SA accumulation, abolishment by bacterial NahG salicylate hydroxylase. Our study revealed that disruption PMR4/GSL5 also leads early senescence. Suppressor analysis uncovered PAD4 N-hydroxypipecolic (NHP) biosynthetic genes ABERRANT GROWTH AND DEATH2-LIKE DEFENSE RESPONSE PROTEIN1 (ALD1) FLAVIN-DEPENDENT MONOXYGENASE1 (FMO1) are senescence mutants. critical role NHP was supported greatly increased accumulation pipecolic contrast, gene ISOCHORISMATE SYNTHASE1/SA-INDUCTION DIFFICIENT 2 (ICS1/SID2), reduces had little effect impaired growth pmr4/gsl5. Furthermore, while completely abolished pmr4/gsl5, mutations ICS1/SID2, ALD1, or FMO1 only a minor mutant plants. However, ICS1/SID2 enhanced immunity against fungal pathogen. Therefore, plays crucial mutants, have important roles induced loss synthase.

Silicon nanoparticles (SiNPs) have emerged as multifunctional tools in sustainable agriculture, demonstrating significant efficacy promoting crop growth and enhancing plant resilience against diverse biotic abiotic stresses. Although their ability to strengthen antioxidant defense systems activate systemic immune responses is well documented, the fundamental mechanisms driving these benefits remain unclear. This review synthesizes emerging evidence propose an innovative paradigm: SiNPs remodel redox signaling networks stress adaptation by forming protein coronas through apoplastic adsorption. We hypothesize that extracellular may elevate reactive oxygen species (ROS) levels adsorbing inhibiting enzymes, thereby intracellular buffering capacity activating salicylic acid (SA)-dependent pathways. Conversely, smaller infiltrating symplastic compartments risk oxidative damage due direct suppression of cytoplasmic systems. Additionally, indirectly influence heavy metal transporter activity state regulation broadly modulate physiological functions via transcription factor regulatory networks. Critical knowledge gaps persist regarding dynamic composition under varying environmental conditions transgenerational impacts. By integrating existing SiNPs, this provides insights potential strategies for developing novel agrochemicals stress-resistant crops.

Many agrochemicals designed to help plants withstand abiotic and biotic stresses can negatively impact the environment. Soil, as an essential natural resource, offers organic matter, nutrients, microbial diversity thrive in challenging environmental conditions. The soil contains plant growth-promoting bacteria that play important role plant/crop productivity, assisting through a variety of mechanisms, including nitrogen fixation, phosphate solubilization, phytohormone production, induction resistance against wide range pathogens, production microbe-to-plant signals regulate aspects responses stress. Plant such Bacillus Paenibacillus contribute sustainable agriculture by enhancing nutrient uptake, acting biocontrol agents, producing lytic enzymes with potential disrupt or destroy pathogenic organisms agricultural medicinal crops soybean cannabis. This review explores mechanisms action bacteria, focusing on species, their enhance, optimize growth promote agriculture.

Plant has an inherent or induced immunity to counter any abiotic biotic stress. Such a response is possible due physiological, molecular and cellular adaptations. Combined effect of stress can provoke cross-tolerance in plants, which may be synergistic antagonistic with the involvement protein kinases, transcription factors, phytohormones, reactive oxygen species (ROS). Priming plant's immune system leads accumulation certain biomolecules like phytoalexins PR proteins inside plant system.

In this study, we show that the potato ( Solanum tuberosum ) pattern recognition receptor (PRR) NEMATODE-INDUCED LEUCINE-RICH REPEAT (LRR)-RLK1 (StNILR1) functions as a dual receptor, recognizing both nematode-associated molecular ascaroside #18 (Ascr18) and plant hormone brassinosteroid (BR) to activate two different physiological outputs: pattern-triggered immunity (PTI) BR response. Ascr18/BR-StNILR1 signaling requires coreceptor BRASSINOSTEROID INSENSITIVE 1-ASSOCIATED RECEPTOR KINASE 1 (StBAK1) perception of either ligand strengthens StNILR1 interaction with StBAK1 in cells. Significantly, parasitically successful cyst nematode Globodera pallida utilizes effector RHA1B, which is functional ubiquitin ligase, target for ubiquitination-mediated proteasome-dependent degradation, thereby countering Ascr18/BR-StNILR1-mediated PTI facilitating parasitism. These findings broaden our understanding PRR specificity reveal parasitic mechanism targets pathway.
