Methyl salicylate is a volatile compound, the synthesis of which takes place via salicylic acid pathway in plants. Both compounds can be involved development systemic acquired resistance and they play their role partly independently. Salicylic transport has an important long-distance signalling, but methyl also been suggested as phloem-based mobile signal, demethylated to form acid, inducing de-novo distal tissue. Despite fact that protective abiotic stress responses tolerance, very few investigations have reported on similar effects salicylate. In addition, are often treated simply non-volatile forms same several cases act way, it hard highlight differences mode action. The main aim present review reveal individual action mechanism resistance, plant-plant communication various conditions fruits

Reactive oxygen species (ROS) are important regulating factors that play a dual role in plant and human cells. As the first messenger response organisms, ROS coordinate signals growth, development, metabolic activity pathways. They also can act as an alarm mechanism, triggering cellular responses to harmful stimuli. However, excess cause oxidative stress-related damage oxidize organic substances, leading malfunctions. This review summarizes current research status mechanisms of eukaryotic cells, highlighting differences similarities between two elucidating their interactions with other reactive substances ROS. Based on similar regulatory pathways kingdoms, this proposes future developments provide opportunities develop novel strategies for treating diseases or creating greater agricultural value.

Volatile uptake, transport, perception, and signaling shape a plant’s nose

Essays in Biochemistry, Год журнала: 2022, Номер 66(5), С. 695 - 702

Опубликована: Сен. 1, 2022

Abstract Herbivore-induced plant volatiles regulate defenses in undamaged neighboring plants. Understanding the mechanisms by which are taken up, perceived, and translated into canonical defense signaling pathways is an important frontier of knowledge. Volatiles can enter plants through stomata cuticle. They likely perceived membrane-associated receptors as well intracellular receptors. The latter involves metabolization transport across cell membranes volatile transporters. Translation priming induction typically mitogen-activated protein kinases (MAPKs), WRKY transcription factors, jasmonates. We propose that broad range molecular processes involved will result substantial spatiotemporal ontogenetic variation responsiveness to volatiles, with consequences for plant–environment interactions.

Pipecolic acid synthesis is required for systemic acquired resistance and plant-to-plant-induced immunity in barley

Journal of Experimental Botany, Год журнала: 2023, Номер 74(10), С. 3033 - 3046

Опубликована: Март 11, 2023

Abstract Defense responses in plants are based on complex biochemical processes. Systemic acquired resistance (SAR) helps to fight infections by (hemi-)biotrophic pathogens. One important signaling molecule SAR is pipecolic acid (Pip), accumulation of which dependent the aminotransferase ALD1 Arabidopsis. While exogenous Pip primes defense monocotyledonous cereal crop barley (Hordeum vulgare), it currently unclear if endogenous plays a role disease monocots. Here, we generated ald1 mutants using CRISPR/Cas9, and assessed their capacity mount SAR. Endogenous levels were reduced after infection mutant, this altered systemic against fungus Blumeria graminis f. sp. hordei. Furthermore, Hvald1 did not emit nonanal, one key volatile compounds that normally emitted activation This resulted inability neighboring perceive and/or respond airborne cues prepare for an upcoming infection, although HvALD1 was required receiver mediate response. Our results highlight crucial SAR, associate Pip, particular together with plant-to-plant propagation monocot barley.

Integrated multi-omics investigation revealed the importance of phenylpropanoid metabolism in the defense response of Lilium regale Wilson to fusarium wilt

Abstract Lilies (genus Lilium) play a significant role in the global cut-flower industry, but they are highly susceptible to fusarium wilt caused by Fusarium oxysporum. However, Lilium regale, wild lily species, exhibits remarkable resistance F. To investigate quantitative of L. regale wilt, comprehensive multi-omics analysis was conducted. Upon inoculation with oxysporum, roots showed accumulation phenylpropane metabolites, including lignin precursors, flavonoids, and hydroxycinnamic acids. These findings were consistent upregulated expression phenylpropanoid biosynthesis-related genes encoding various enzymes, as revealed transcriptomics proteomics analyses. Furthermore, metabolomics data demonstrated differential activation monoterpenoid isoquinoline alkaloid biosynthesis. Colorimetry high-performance liquid chromatography analyses significantly higher levels total lignin, ferulic acid, phlorizin, quercetin contents scales compared ‘Siberia’ during oxysporum infection. phenylpropanes exhibited inhibitory effects on growth suppressed pathogenicity-related genes. Transcriptional regulatory network suggested that ethylene-responsive transcription factors (ERFs) may positively regulate Therefore, LrERF4 cloned transiently overexpressed wilt-susceptible Oriental hybrid ‘Siberia’. The overexpression resulted increased quercetin, while silencing through RNAi had opposite effect. In conclusion, metabolism plays crucial defense response against acting positive regulator

Tuning the Wavelength: Manipulation of Light Signaling to Control Plant Defense

International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(4), С. 3803 - 3803

The growth-defense trade-off in plants is a phenomenon whereby must balance the allocation of their resources between developmental growth and defense against attack by pests pathogens. Consequently, there are series points where signaling can negatively regulate defenses inhibit growth. Light perception various photoreceptors has major role control thus many it influence defense. Plant pathogens secrete effector proteins to manipulate hosts. Evidence emerging that some these effectors target light pathways. Several from different kingdoms life have converged on key chloroplast processes take advantage regulatory crosstalk. Moreover, plant also perceive react complex ways own growth, development, virulence. Recent work shown varying wavelengths may provide novel way controlling or preventing disease outbreaks plants.

Redox-signaling in innate immune memory: Similar mechanisms in animals and plants

Redox Biology, Год журнала: 2025, Номер 84, С. 103702 - 103702

Опубликована: Май 27, 2025

Plants and animals/humans have evolved sophisticated innate immune systems to cope with microbial attack. Innate immunity implies the presence of membrane-located intracellular receptors recognize compounds released by damage or invading pathogens. After detection receptor molecules initiate defense signaling, resulting in cell death and/or production molecules. Interestingly, response includes also memory mechanisms, which allow organisms better future attacks. Redox mechanisms play an important role signaling. In this review article, we compare plants describe how reversible nitric oxide- reactive oxygen species-dependent protein modifications enable activation signaling proteins transcription factors regulate activity chromatin modifying enzymes establish memory. We hope encourage efforts characterize further molecular redox memory, might development new immunotherapies.

Both above- and below-ground parts of plants are constantly challenged with microbes interact closely them. Many plant-growth-promoting rhizobacteria, mostly interacting the plant's root system, enhance immunity in a process described as induced systemic resistance (ISR). Here, we characterized local (IR) triggered by model PGPR Pseudomonas simiae WCS417r (WCS417) Arabidopsis thaliana. Hydroponic application WCS417 to roots resulted propagation in/on leaves establishment IR. WCS417-triggered IR was dependent on salicylic acid (SA) biosynthesis signalling functional pipecolic monoterpenes, which classically associated acquired (SAR). further priming gene expression changes related SA SAR. A metabarcoding approach applied leaf microbiome revealed significant IR-associated enrichment Flavobacterium sp.. Co-inoculation experiments using At-LSPHERE sp. Leaf82 suggest that proliferation these bacteria is influenced both microbial immunity-related, plant-derived factors. Furthermore, SAR an NPR1-dependent manner, suggesting recruitment this bacterium phyllosphere Together, data highlight importance plant-microbe-microbe interactions reveal new beneficial promoter plant health.
