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.

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.

Summary Plants activate induced defenses through the recognition of molecular patterns. Like pathogen-associated patterns (PAMPs), herbivore-associated (HAMPs) can be recognized by cell surface pattern receptors leading to defensive transcriptional changes in host plants. Herbivore-induced outputs are regulated circadian clock, but underlying mechanisms remain unknown. To investigate how plant clock regulates reprogramming a specific HAMP-induced pathway, we characterized daytime and nighttime response caterpillar-derived In11 peptide, legume crop cowpea ( Vigna unguiculata ). Using diurnal free-running conditions, found that elicitation resulted stronger late-induced gene expression than nighttime. with conditional arrhythmic phenotype constant light (LL) conditions lost time-of-day dependent responses treatment, this was associated core transcription factor Late Elongated Hypocotyl VuLHY1 VuLHY2 . Reporter assays VuLHY homologs indicated they interact promoter In11-induced Kunitz Trypsin Inhibitor VuKTI ) via canonical polymorphic CCA1/LHY Binding Site (CBS), consistent mechanism direct regulation factors. This study improves our understanding time-dependent regulate herbivore-induced expression.
