Plant Disease Resistance-Related Signaling Pathways: Recent Progress and Future Prospects

International Journal of Molecular Sciences, Год журнала: 2022, Номер 23(24), С. 16200 - 16200

Опубликована: Дек. 19, 2022

Plant–pathogen interactions induce a signal transmission series that stimulates the plant’s host defense system against pathogens and this, in turn, leads to disease resistance responses. Plant innate immunity mainly includes two lines of system, called pathogen-associated molecular pattern-triggered (PTI) effector-triggered (ETI). There is extensive exchange recognition process triggering plant immune signaling network. messenger molecules, such as calcium ions, reactive oxygen species, nitric oxide, hormone salicylic acid, jasmonic ethylene, play key roles inducing In addition, heterotrimeric G proteins, mitogen-activated protein kinase cascade, non-coding RNAs (ncRNAs) important regulating transduction This paper summarizes status progress pathway research recent years; discusses complexities of, among, pathways; forecasts future prospects provide new ideas for prevention control diseases.

Molecular tug-of-war: Plant immune recognition of herbivory

The Plant Cell, Год журнала: 2022, Номер 34(5), С. 1497 - 1513

Abstract Plant defense responses against insect herbivores are induced through wound-induced signaling and the specific perception of herbivore-associated molecular patterns (HAMPs). In addition, can deliver effectors that suppress plant immunity. Here we review immune recognition HAMPs effectors, argue these initial interactions upon a plant–herbivore encounter mediate structure effective resistance. While number distinct from both chewing piercing–sucking has expanded rapidly with omics-enabled approaches, paired receptors targets in host still not well characterized. Herbivore-derived may also be recognized as depending on species, potentially evolution novel receptor functions. We compile examples where natural variation between species inform evolutionary mechanisms interactions. Finally, discuss combined effects wounding HAMP recognition, potential hubs, which integrate sensing Understanding precise for will critical engineering resistance agriculture.

Pathogen perception and signaling in plant immunity

The Plant Cell, Год журнала: 2024, Номер 36(5), С. 1465 - 1481

Abstract Plant diseases are a constant and serious threat to agriculture ecological biodiversity. Plants possess sophisticated innate immunity system capable of detecting responding pathogen infection prevent disease. Our understanding this has grown enormously over the past century. Early genetic descriptions plant disease resistance virulence were embodied in gene-for-gene hypothesis, while physiological studies identified pathogen-derived elicitors that could trigger defense responses cells tissues. Molecular these phenomena have now coalesced into an integrated model involving cell surface intracellular detection specific molecules proteins culminating induction various cellular responses. Extracellular receptors engage distinct signaling processes but converge on many similar outputs with substantial evidence for integration pathways interdependent networks controlling outcomes. Many molecular details recognition known, providing opportunities bioengineering enhance protection from Here we provide overview current main principles immunity, emphasis key scientific milestones leading insights.

Magnaporthe oryzae is the causal agent of rice blast disease, most widespread and serious disease cultivated rice. Live cell imaging quantitative 4D image analysis have provided new insight into mechanisms by which fungus infects host cells spreads rapidly in plant tissue. In this video review article, we apply live approaches to understanding developmental biology disease. To gain entry plants, M. develops a specialised infection structure called an appressorium, unicellular dome-shaped generates enormous turgor, translated mechanical force rupture leaf cuticle. Appressorium development induced perception hydrophobic surface nutrient deprivation.

Host Adaptation and Virulence in Heteroecious Rust Fungi

Annual Review of Phytopathology, Год журнала: 2021, Номер 59(1), С. 403 - 422

Опубликована: Июнь 2, 2021

Rust fungi (Pucciniales, Basidiomycota) are obligate biotrophic pathogens that cause rust diseases in plants, inflicting severe damage to agricultural crops. Pucciniales possess the most complex life cycles known fungi. These include an alternation of generations, development up five different sporulating stages, and, for many species, requirement infecting two unrelated host plants during parts their cycle, termed heteroecism. have been extensively studied past century through microscopy and inoculation studies, providing precise descriptions infection processes, although molecular mechanisms underlying unique biology poorly understood. In this review, we cover recent genomic cycle transcriptomic studies several heteroecious which provide insights into genetic tool kits associated with adaptation virulence, opening new avenues unraveling evolution.

Future of Bacterial Disease Management in Crop Production

Annual Review of Phytopathology, Год журнала: 2022, Номер 60(1), С. 259 - 282

Опубликована: Июль 6, 2022

Bacterial diseases are a constant threat to crop production globally. Current management strategies rely on an array of tactics, including improved cultural practices; application bactericides, plant activators, and biocontrol agents; use resistant varieties when available. However, effective remains challenge, as the longevity deployed tactics is threatened by constantly changing bacterial populations. Increased scrutiny impact pesticides human environmental health underscores need for alternative solutions that durable, sustainable, accessible farmers, environmentally friendly. In this review, we discuss strengths shortcomings existing practices dissect recent advances may shape future disease management. We conclude resistance through genome modification be most arsenal against diseases. Nonetheless, more research necessary developing novel meet food demand growing global population.

Transcriptomic and Metabolomic Approaches Deepen Our Knowledge of Plant–Endophyte Interactions

Frontiers in Plant Science, Год журнала: 2022, Номер 12

Опубликована: Янв. 27, 2022

In natural systems, plant-symbiont-pathogen interactions play important roles in mitigating abiotic and biotic stresses plants. Symbionts have their own special recognition ways, but they may share some similar characteristics with pathogens based on studies of model microbes Multi-omics technologies could be applied to study plant-microbe interactions, especially plant-endophyte interactions. Endophytes are naturally occurring that inhabit plants, do not cause apparent symptoms them, arise as an advantageous source novel metabolites, agriculturally promoters, stress resisters host Although biochemical, physiological, molecular investigations demonstrated endophytes confer benefits hosts, terms promoting plant growth, increasing metabolic capabilities, enhancing resistance, consist complex mechanisms between the two symbionts. Further knowledge these gained by adopting a multi-omics approach. The involved interaction, which can range from colonization protection against adverse conditions, has been investigated transcriptomics metabolomics. This review aims provide effective means ways applying solve current problems characterization involving colonization. obtained results should useful for identifying key determinants such would also timely theoretical material basis interaction applications.
