Abstract To adapt to each other, plants and insect herbivores have developed sophisticated molecular interactions. Here, we summarize current knowledge about such interactions between rice, a globally important food crop, herbivores. When infested by herbivores, rice perceives herbivore- and/or damage-associated patterns (HAMPs/DAMPs) via receptors that activate early signaling events as the influx of Ca 2+ , burst reactive oxygen species, activation MPK cascades. These changes result in specific defenses networks mainly include phytohormones (jasmonic acid, salicylic ethylene, abscisic acid) transcription factors. Some compounds, including flavonoids, phenolamides, defensive proteins, herbivore-induced volatiles, been reported be used against insects. Insect can deliver effectors or factors inhibit enhance susceptibility. Although number HAMPs defense-suppressing from piercing-sucking insects has increased rapidly, none chewing identified. Moreover, herbivore induce susceptibility, immune recognizing effectors, are not well characterized. We point out future research directions this area highlight importance elucidating mechanisms for sensing counter-defenses plants.

Summary Nucleotide‐binding domain and leucine‐rich repeat (NLR) proteins are important intracellular immune receptors that activate robust plant responses upon detecting pathogens. Canonical NLRs consist of a conserved tripartite architecture includes central regulatory nucleotide‐binding domain, C‐terminal repeats, variable N‐terminal domains directly participate in execution. In flowering plants, the vast majority NLR belong to coiled‐coil, Resistance Powdery Mildew 8, or Toll/interleukin‐1 receptor subfamilies, with recent structural biochemical studies providing detailed mechanistic insights into their functions. this insight review, we focus on immune‐related biochemistries known discuss evolutionary diversity atypical nonflowering plants. We further contrast these observations against NLR‐related from microbes metazoans across tree life.

Calcium ions (Ca2+) serve as key messengers in plant immune reactions. A typical Ca2+ signaling involves three steps: encoding specific signatures by Ca2+-permeable channels, decoding signals sensors, and downstream responses. This review focuses on plasma membrane-localized channels cytosolic unraveling their roles influx during pattern-triggered immunity, effector-triggered autoimmunity. Several unresolved questions were highlighted, including the regulation of channel activity for induction mechanism behind influx-triggered hypersensitive response cell death. concise overview provides insights into complex interplay paving way future investigations molecular plant-microbe interactions.

SUMMARY Nucleotide‐binding leucine‐rich repeat (NLR) proteins are crucial intracellular immune receptors in plants, responsible for detecting invading pathogens and initiating defense responses. While previous studies on the evolution function of NLR genes were mainly limited to land evolutionary trajectory immune‐activating character algae remain less explored. In this study, genome‐wide gene analysis was conducted 44 chlorophyte species across seven classes charophyte five classes. A few but variable number genes, ranging from one 20, identified chlorophytes three charophytes, whereas no remaining algal genomes. Compared with genomes possess fewer or usually implying that expansion plants can be attributed their adaptation more complex terrestrial pathogen environments. Through phylogenetic analysis, domain composition conserved motifs profiling NBS domain, we detected shared lineage‐specific features between supporting common origin continuous green plant genes. Immune‐activation assays revealed both TNL RNL elicit hypersensitive responses Nicotiana benthamiana , indicating molecular basis activation has emerged early stage different types proteins. summary, results study suggest may have taken a role as ancestor plants.

Wheat is cultivated across diverse global environments, and its productivity significantly impacted by various biotic stresses, most importantly but not limited to rust diseases, Fusarium head blight, wheat blast, powdery mildew. The genetic diversity of modern cultivars has been eroded domestication selection, increasing their vulnerability stress due uniformity. rapid spread new highly virulent aggressive pathogen strains exacerbated this situation. Three strategies can be used for enhancing disease resistance through genome editing: introducing (R) gene-mediated resistance, engineering nucleotide-binding leucine-rich repeat receptors (NLRs), manipulating susceptibility (S) genes stop pathogens from exploiting these factors support infection. Utilizing R the common strategy traditional breeding approaches, continuous evolution effectors eventually overcome resistance. Moreover, modifying S confer pleiotropic effects that hinder use in agriculture. Enhancing paramount sustainable production food security, tools are great importance research community. application CRISPR-based editing provides promise improve allowing access a broader range solutions beyond random mutagenesis or intraspecific variation, unlocking ways crops, speeding up breeding. Here, we first summarize major context important diseases limitations. Next, turn our attention powerful applications technology creating varieties against diseases.

Late blight, caused by the oomycete plant pathogen Phytophthora infestans, is a destructive disease that leads to significant yield loss in potatoes and tomatoes. The introgression of resistance (R) genes, which encode nucleotide-binding domain leucine-rich repeat-containing receptors (NLRs), into cultivated potatoes, highly effective controlling late blight. Here, we generated transgenic 2R 3R potato lines stacking R genes Rpi-blb2/Rpi-vnt1.1 Rpi-vnt1.1/RB/R8, respectively, susceptible cv. Desiree background. resulting plants showed virulent P. infestans field isolates. We hypothesized either resulted up-regulation broader range immune-related or, more importantly, increase fold change gene expression. To test our hypotheses, performed transcriptome analysis identified subset core are induced response carrying single versus stacks multiple genes. In analysis, not only induction defense-associated but also global expression change, pathogen. further demonstrated calcium-dependent protein kinase 16 (StCDPK16) significantly contributed strain, background, activity-dependent manner. Thus, data suggest enhances blight through modulating defense-related highlights CDPK16 as novel player gene-mediated resistance.
