Volatile-mediated plant–plant interactions: volatile organic compounds as modulators of receiver plant defence, growth, and reproduction

Journal of Experimental Botany, Journal Year: 2021, Volume and Issue: 73(2), P. 511 - 528

Published: Nov. 5, 2021

Abstract It is firmly established that plants respond to biotic and abiotic stimuli by emitting volatile organic compounds (VOCs). These VOCs provide information on the physiological status of emitter plant are available for detection whole community. In context plant–plant interactions, research has focused mostly defence-related responses receiver plants. However, may span hormone signalling both primary secondary metabolism, ultimately affect fitness. Here we present a synthesis focusing effects VOC exposure An overview important chemical cues, uptake conversion VOCs, adsorption surfaces presented. This followed review substantial VOC-induced changes affecting metabolism influencing growth reproduction. Further should consider whole-plant effective evaluation mechanisms fitness consequences VOCs.

Isoprene and β‐caryophyllene confer plant resistance via different plant internal signalling pathways

Plant Cell & Environment, Journal Year: 2021, Volume and Issue: 44(4), P. 1151 - 1164

Isoprene and other terpenoids are important biogenic volatile organic compounds in terms of atmospheric chemistry. can aid plant performance under abiotic stresses, but the fundamental biological reasons for high emissions not completely understood. Here, we provide evidence a previously unrecognized ecological function isoprene sesquiterpene, ß-caryophyllene. We show that ß-caryophyllene act as core components signalling networks, inducing resistance against microbial pathogens neighbouring plants. challenged Arabidopsis thaliana with Pseudomonas syringae, after exposure to pure or transformed poplar The data suggest induces defence response receiver plants is similar elicited by monoterpenes depended on salicylic acid (SA) signalling.

Unravelling the functions of biogenic volatiles in boreal and temperate forest ecosystems

European Journal of Forest Research, Journal Year: 2019, Volume and Issue: 138(5), P. 763 - 787

Living trees are the main source of biogenic volatile organic compounds (BVOCs) in forest ecosystems, but substantial emissions originate from leaf and wood litter, rhizosphere microorganisms. This review focuses on temperate boreal ecosystems roles BVOCs ecosystem function, to canopy soil atmosphere level. Moreover, emphasis is given question how will help forests adapt environmental stress, particularly biotic stress related climate change. Trees use their vascular system internal communication, emitted have extended communication tree population whole community levels beyond. Future forestry practices should consider importance attraction repulsion attacking bark beetles, also take an advantage herbivore-induced improve efficiency natural enemies herbivores. extensively involved services provided by including positive effects human health. a key role ozone formation quenching.

Volatile organic compounds in the interaction between plants and beneficial microorganisms

Journal of Plant Interactions, Journal Year: 2022, Volume and Issue: 17(1), P. 840 - 852

Published: Aug. 6, 2022

A growing population coupled with a higher demand for food is putting pressure on agriculture. The use of synthetic pesticides and chemical fertilizers allowed us to boost agricultural productions, but at great environmental cost. Exploitation beneficial microorganism (BM)-plant interactions has been proposed as an eco-friendly solution improve plant resistance stresses increase productivity sustainably. We provide overview scientific evidence that this positive interaction often mediated also by the release microbial Volatile Organic Compounds (mVOCs). few mVOCs are reported have double, not mutually exclusive, effect plants, growth promoters, and/or inducers against biotic abiotic stress factors. They may alter VOCs indirectly improving performances. However, mechanisms functions need deeper investigation. By understanding mVOC modes action further tools sustainably in agro-ecosystems become soon available.

Atmospheric chemists have historically treated leaves as inert surfaces that merely emit volatile hydrocarbons. However, a growing body of evidence suggests are ubiquitous substrates for multiphase reactions-implying the presence chemicals on their surfaces. This Review provides an overview chemistry and reactivity leaf surface's "chemical landscape", dynamic ensemble compounds covering plant leaves. We classified endogenous (originating from its biome) or exogenous (delivered environment), highlighting biological, geographical, meteorological factors driving contributions.

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

Journal of Experimental Botany, Journal Year: 2023, Volume and Issue: 74(10), P. 3033 - 3046

Published: March 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.
