Volatile compound-mediated plant–plant interactions under stress with the tea plant as a model

Horticulture Research, Год журнала: 2023, Номер 10(9)

Опубликована: Июль 21, 2023

Plants respond to environmental stimuli via the release of volatile organic compounds (VOCs), and neighboring plants constantly monitor these VOCs with great sensitivity discrimination. This sensing can trigger increased plant fitness reduce future damage through priming their own defenses. The defense mechanism in either be induced by activation regulatory or transcriptional machinery, it delayed absorption storage for generation an appropriate response later. Despite much research, many key questions remain on role interplant communication fitness. Here we review recent research biotic (i.e. insects pathogens) abiotic cold, drought, salt) stresses, elucidate biosynthesis stress-induced tea plants. Our focus is complex ecological environments. Particularly, roles under stress are highlighted. Finally, discuss pertinent directions advancing our understanding interactions VOCs.

Abstract Revalorized olive waste impacts root microbiome. Root microbiome modulates plant-induced defense. Insect’s exudate simulates the pest attack. The objective of this study was to investigate combined effect soil amendments and attack on defense their impact a biological control agent’s behavior. effects mill wastes revalorized through vermicomposting aboveground tri-trophic interactions among trees ( Olea europaea ), seed-feeder, Prays oleae , its natural predator, Chrysoperla carnea were evaluated. findings demonstrate that nitrogen organic carbon levels, in conjunction with fungal diversity functionality within roots, exert significant influence volatile compounds emitted by plant under are most appealing C. . Moreover, attractiveness aerial volatiles found correlate content taxonomic functional both bacteria fungi system. It is worthy note three particular compounds, namely 5-hepten-2-one-6-methyl, acetic acid nonanal, consistently observed attract These highlight potential enhance strategies.

High-resolution kinetics of herbivore-induced plant volatile transfer reveal clocked response patterns in neighboring plants

eLife, Год журнала: 2024, Номер 12

Опубликована: Фев. 22, 2024

Volatiles emitted by herbivore-attacked plants (senders) can enhance defenses in neighboring (receivers), however, the temporal dynamics of this phenomenon remain poorly studied. Using a custom-built, high-throughput proton transfer reaction time-of-flight mass spectrometry (PTR-ToF-MS) system, we explored patterns volatile and responses between undamaged maize plants. We found that continuous exposure to natural blends herbivore-induced volatiles results clocked response plants, characterized an induced terpene burst at onset second day exposure. This delayed is not explained accumulation during night, but coincides with jasmonate receiver The occurs independent day:night light transitions cannot be fully sender dynamics. Instead, it result stress memory from first secondary bioactive on day. Our study reveals prolonged stress-induced integrates priming direct induction into distinct predictable pattern. provides answer long-standing question whether predominantly induce or prime plant revealing they do both sequence.

Threats to food security require novel sustainable agriculture practices manage insect pests. One strategy is conservation biological control (CBC), which relies on pest services provided by local populations of arthropod natural enemies. Research has explored manipulative use chemical information from plants and insects that act as attractant cues for enemies (predators parasitoids) repellents In this review, we reflect past strategies using ecology in CBC, such herbivore-induced plant volatiles the push-pull technique, propose future directions, including leveraging induced defenses crop plants, repellent insect-based signaling, genetically engineered crops. Further, discuss how climate change may disrupt CBC stress importance context dependency yield outcomes.

Leaf Size Determines Damage‐ and Herbivore‐Induced Volatile Emissions in Maize

Plant Cell & Environment, Год журнала: 2025, Номер unknown

Опубликована: Янв. 16, 2025

ABSTRACT Stress‐induced plant volatiles play an important role in mediating ecological interactions between plants and their environment. The timing location of the inflicted damage is known to influence quality quantity induced volatile emissions. However, how leaf characteristics herbivore feeding behaviour interact shape emissions not well understood. Using a high‐throughput profiling system with high temporal resolution, we examined mechanical on different leaves plant‐level emission patterns maize. We then tested resulting consequences two generalist herbivores ( Spodoptera exigua littoralis ), assessed whether preferences are associated enhanced performance. found maize seedlings emit more when larger damaged. Larger emitted locally, which was determining factor for higher Surprisingly, both S. preferentially consumed leaves, thus maximize without apparent growth benefits. Together, these findings provide ecophysiological behavioural mechanism patterns, potentially implications volatile‐mediated plant‐environment interactions.

Squalene acts as a feedback signaling molecule in facilitating bidirectional communication between tea plants

Science Advances, Год журнала: 2025, Номер 11(7)

Опубликована: Фев. 14, 2025

Plants respond to environmental stimuli by releasing volatile organic compounds (VOCs), which play diverse roles in plant-to-plant interactions. Previous studies have primarily focused on how receiving plants respond. However, little is known about these receivers communicate back the emitter and their subsequent impacts. Our findings indicated increased plant tolerance when neighboring were present, suggesting bidirectional communication. Furthermore, we established a model explore role of signals from receiver plants, identifying squalene as crucial feedback signal enhancing cold up-regulating CsCBF5 expression. Further analysis using yeast one-hybrid coupled with inhibition brassinosteroid pathways suggested that squalene-induced castasterone (CS) accumulation directly activated expression modulated CsBES1/BZR1 . Overall, results demonstrated squalene-CS- BES1/BZR1 - CBF5 pathway communication between expanding our understanding

Plant Defense Responses to Insect Herbivores Through Molecular Signaling, Secondary Metabolites, and Associated Epigenetic Regulation

Plant-Environment Interactions, Год журнала: 2025, Номер 6(1)

Опубликована: Фев. 1, 2025

ABSTRACT Over millions of years interactions, plants have developed complex defense mechanisms to counteract diverse insect herbivory strategies. These defenses encompass morphological, biochemical, and molecular adaptations that mitigate the impacts herbivore attacks. Physical barriers, such as spines, trichomes, cuticle layers, deter herbivores, while biochemical include production secondary metabolites volatile organic compounds (VOCs). The initial step in plant's involves sensing mechanical damage chemical cues, including oral secretions herbivore‐induced VOCs. This triggers changes plasma membrane potential driven by ion fluxes across plant cell membranes, activating signal transduction pathways. Key hormonal mediators, jasmonic acid, salicylic ethylene, orchestrate downstream responses, VOC release biosynthesis. review provides a comprehensive analysis responses herbivory, emphasizing early late mechanisms, encompassing physical cascades, synthesis, phytohormone signaling, epigenetic regulation.
