Light induces an increasing release of benzyl nitrile against diurnal herbivore Ectropis grisescens Warren attack in tea (Camellia sinensis) plants

Plant Cell & Environment, Journal Year: 2023, Volume and Issue: 46(11), P. 3464 - 3480

Published: Aug. 8, 2023

Herbivore-induced plant volatiles (HIPVs) are critical compounds that directly or indirectly regulate the tritrophic interactions among herbivores, natural enemies and plants. The synthesis release of HIPVs regulated by many biotic abiotic factors. However, mechanism which multiple factors synergistically affect remains unclear. Tea (Camellia sinensis) is object this study because its rich varied volatile metabolites. In study, benzyl nitrile was released from herbivore-attacked tea plants more in daytime than at night, consistent with feeding behaviour geometrid (Ectropis grisescens Warren) larvae.

Plant communication across different environmental contexts suggests a role for stomata in volatile perception

Plant Cell & Environment, Journal Year: 2023, Volume and Issue: 46(7), P. 2017 - 2030

Published: May 11, 2023

Abstract Plants can detect herbivore‐induced plant volatiles (HIPVs) from their damaged neighbours and respond by enhancing or priming defenses against future herbivore attack. Plant communication defense volatile cues has been well documented, however, the extent to which plants are able perceive these across different environmental contexts remains poorly understood. We investigated how abiotic changes that modulate stomatal conductance and/or signalling affect ability of maize HIPVs defenses. During light exposure, when stomata were open conditions allowed for signal biosynthesis, individual compounds indole ( Z )−3‐hexenyl acetate primed Neither compound under closed altered signalling. Moreover, not exposed in darkness (while closed) then subjected simulated herbivory light, ensure induction. The full blend but suppressed induction during dark exposure wounding. These findings indicate context is important suggest play a role perception HIPVs.

Belowground insect herbivory induces systemic volatile emissions that strengthen neighbouring plant resistance aboveground

Plant Cell & Environment, Journal Year: 2023, Volume and Issue: 47(2), P. 714 - 725

Published: Nov. 14, 2023

Abstract Plants transmit ecologically relevant messages to neighbouring plants through chemical cues. For instance, insect herbivory triggers the production of herbivore‐induced plant volatiles (HIPVs), which can enhance defences. HIPVs are emitted from directly damaged tissues and systemic, nondamaged tissues. Although volatile‐mediated interplant interactions have been observed both above‐ belowground, it remains unknown whether belowground induces systemic aboveground that influence plants. To explore how affects aboveground, we characterised squash induced by striped cucumber beetle ( Acalymma vittatum ) larval herbivory. We exposed ‘receiver plants’ or then measured herbivore resistance challenging with aboveground‐feeding herbivores: adult beetles A. bugs Anasa tristis ). discovered belowground‐damaged more E )‐β‐ocimene, a key volatile HIPV blend, than controls, exposure enhanced bugs, but not beetles. Further investigations into mechanism interaction revealed β‐ocimene alone elicit against bugs. Overall, our findings reveal novel form between spanning across aboveground–belowground systems.

Volatile-mediated between-plant communication in Scots pine and the effects of elevated ozone

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2022, Volume and Issue: 289(1982)

Published: Sept. 7, 2022

Conifers are dominant tree species in boreal forests, but susceptible to attack by bark beetles. Upon beetle attack, conifers release substantial quantities of volatile organic compounds known as herbivore-induced plant volatiles (HIPVs). Earlier studies broadleaved plants have shown that HIPVs provide information neighbouring plants, which may enhance their defences. However, the defence responses HIPV-receiver not been described for conifers. Here we advance knowledge plant–plant communication documenting a suite receiver-plant bark-feeding-induced volatiles. Scots pine seedlings exposed were more resistant subsequent weevil feeding and received less damage. Receiver had both induced primed emissions resin ducts an increased epithelial cell (EC) mean area number cells located second EC layer. Importantly, HIPV exposure stomatal conductance net photosynthesis rate receiver plants.

Tree Communication: the Effects of “Wired” and “Wireless” Channels on Interactions with Herbivores

Current Forestry Reports, Journal Year: 2022, Volume and Issue: 9(1), P. 33 - 47

Abstract Purpose of Review Approximately 40 years ago, key papers indicating that volatile chemicals released by damaged plants elicited defense-related changes in their neighbors, brought prominence to the idea plant communication. These studies were conducted with several tree species and phenomenon observed was dubbed “talking trees.” Today there is a wealth evidence supporting can send receive information both above belowground. However, while early reports plant-plant communication concerned trees, literature now heavily biased towards herbaceous plants. The purpose this review highlight recent research on tree-tree an emphasis synthesizing knowledge ecological relevance process. Recent Findings Aboveground, often provided form biogenic organic compounds (VOCs), which are undamaged blends VOCs provide physiological condition. Belowground, conveyed through mycorrhizal networks via chemical exudates into rhizosphere. findings have indicated sophistication more effective VOC-mediated interactions between trees same versus different genotype, kin-group, or chemotype. Moreover, common been shown convey stress-related signals intra- interspecific associations. Together these two forms represent “wireless” “wired” channels significance facilitating resistance herbivores. Summary In review, we examine focus natural forest ecosystems. We particularly address effects herbivorous insects. Aboveground belowground reviewed suggested implications for management future presented.

Biogenic secondary organic aerosol participates in plant interactions and herbivory defense

Science, Journal Year: 2024, Volume and Issue: 385(6714), P. 1225 - 1230

Published: Sept. 12, 2024

Biogenic secondary organic aerosols (SOAs) can be formed from the oxidation of plant volatiles in atmosphere. Herbivore-induced (HIPVs) elicit defenses, but whether such ecological functions persist after they form SOAs was previously unknown. Here we show that Scots pine seedlings damaged by large weevils feeding on their roots release HIPVs trigger defenses neighboring conspecific plants. The biological activity persisted had been oxidized to SOAs, which indicated receivers displaying enhanced photosynthesis, primed volatile and reduced weevil damage. elemental composition quantity likely determines functions. This work demonstrates plant-derived mediate interactions between plants, highlighting significance ecosystems.

The combination of biochar and nitrogen (N) fertilization in agricultural salt-affected soils is an effective strategy for amending the soil promoting production. To investigate effect reduction combined with application on a soda saline soybean growth black areas, pot experiment was set up two levels, 0 (B0) 4.5 t/hm2 (B1); depths, 0-20 cm (H1) 0-40 (H2); conventional (N0) 15% (N1). results showed that improved status significantly increased yield under lower application. Moreover, increasing depth enhanced effectiveness reducing barriers to crop growth, which promoted growth. Increasing K+ Ca2+ contents, content, N fertilizer agronomic efficiency, leaf total nitrogen, use AN, Tr, gs, SPAD, water potential, content its components. However, Na+ SAR, ESP, Na+/K+, Ci efficiency decreased depth. Among treatments low input biochar, B1H1N1 resulted greatest improvement layer compared B0N0; example, by 61.87%, 44.80%, SAR 46.68%, nitrate 26.61%. 20-40 layer, B1H2N1 had improving physicochemical properties, 62.54%, 29.76%, 32.85%, 30.77%. In addition, B0N0, 25.07%, 6.7%, 32.79%, partial factor productivity 28.37%, gs 22.10%, potential 27.33% 6.44%. conclusion, condition soil; it not only effectively regulated distribution salt provided low-salt environment but also activated deep resources. Therefore, among all investigated this study, considered most suitable areas enhancing plants.
