Biosensors, Journal Year: 2023, Volume and Issue: 13(8), P. 796 - 796

Most agricultural land, as a result of climate change, experiences severe stress that significantly reduces yields. Crop sensing by imaging techniques allows early-stage detection biotic or abiotic to avoid damage and significant yield losses. Among the top certified for plant is chlorophyll fluorescence imaging, which can evaluate spatiotemporal leaf changes, permitting pre-symptomatic monitoring physiological status long before any visible symptoms develop, allowing high-throughput assessment.

Deciphering Plant-Insect-Microorganism Signals for Sustainable Crop Production

Biomolecules, Journal Year: 2023, Volume and Issue: 13(6), P. 997 - 997

Published: June 15, 2023

Agricultural crop productivity relies on the application of chemical pesticides to reduce pest and pathogen damage. However, also pose a range ecological, environmental economic penalties. This includes development pesticide resistance by insect pests pathogens, rendering less effective. Alternative sustainable protection tools should therefore be considered. Semiochemicals are signalling molecules produced organisms, including plants, microbes, animals, which cause behavioural or developmental changes in receiving organisms. Manipulating semiochemicals could provide more approach management pathogens across crops. Here, we review role interaction between insects examples how they have been applied agricultural systems. We highlight future research priorities considered for credible alternatives pesticides.

Elevated O₃ threatens biological communications mediated by plant volatiles: A review focusing on the urban environment

Critical Reviews in Environmental Science and Technology, Journal Year: 2023, Volume and Issue: 53(22), P. 1982 - 2001

Published: April 20, 2023

Plant volatiles, particularly biogenic volatile organic compounds (BVOCs), emitted in urban areas have attracted attention as olfactory signals between plants and other organisms, including insects. However, areas, elevated ozone (O3) levels inhibit plant growth degrade signals, both insect pheromones BVOCs, resulting disrupted biological communication. In this article, we review recent findings on how O3 modifies interactions, focusing the emitters receivers of these signals. The influence herbivorous insects their enemies alters pressure caused by damage field, which can affect development defensive capacities at hereditary level. To address challenges posed BVOC characteristics (e.g., emission rate species, blend composition, reactivity, oxidative products) effects preference antennal detectivity) should be clarified. At same time, emissions are expected to increase with rising temperatures, will likely impact BVOCs formation future. Therefore, it is necessary devise strategies, such selecting non- or low emitters, regulate from greening mitigate risks interactions health.

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.

Tomato Defenses Under Stress: The Impact of Salinity on Direct Defenses Against Insect Herbivores

Plant Cell & Environment, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 13, 2025

ABSTRACT Abiotic stressors, such as salt stress, can reduce crop productivity, and when combined with biotic pressures, insect herbivory, exacerbate yield losses. However, salinity‐induced changes to plant quality defenses in turn affect herbivores feeding on plants. This study investigates how salinity stress tomato plants ( Solanum Lycopersicum cv. Better Boy) impacts the behavior performance of a devastating pest, fruitworm caterpillar Helicoverpa zea ). Through choice assays experiments, we demonstrate that salt‐stressed are poor hosts for H. , negatively affecting preferences growth rates. While nutritional were observed, primary factor influencing appears be direct ionic toxicity, which significantly impairs multiple life history parameters including survival, pupation, adult emergence, fecundity. Plant defense responses show complex interactions between two proteinase inhibitor genes ‐ PIN2 AspPI showing higher induced response herbivory under conditions. do not seem main driver reduced salt‐treated Furthermore, report oviposition by moths plants, was correlated altered volatile emissions.

Abstract Low soil moisture, a prominent indicator of changing climate, has overarching impacts on plant reproduction both directly and indirectly by affecting the visitation rate pollinators. However, role moisture in modifying behaviours species interacting with plants is less well explored, as are mechanisms associated those changes behaviour. Reduced can disrupt mutualistic interactions, potentially shifting them toward antagonism negatively impacting fitness. We investigated effects underlying intensity nectar robbing (a common behavioural interaction between pollinators) natural populations Primula florindae southeast Tibetan Plateau. To understand relationships involved, we explored within‐population variation robbing, floral traits, diversity evenness co‐flowering community areas moisture. then used an experimental approach to test how affected male female components P. reproduction. found that growing low experienced higher robbing. was reduced flower size, production, nectariferous neighbour plants. only size (an estimate accessibility) had significant effect triggering morphological mismatch flowers primary bumblebee pollinators, prompting shift behaviours.
