[学术文献 ] Potential of service plants for regulating multiple pests while limiting disservices in agroecosystems. A review 进入全文
Agronomy for Sustainable Development 期刊
Here, a trait-based approach was used to provide an overview of the potentialities of service plants, (inserted either in intercropping, in rotation with the crops, or in field edges) for regulating multiple pests, while limiting disservices. For that purpose, we first laid the foundation of a conceptual framework by synthesizing the mechanisms and service plant traits involved in the regulation of each pest category and in the mitigation of each disservice. On this basis, we analyzed (1) the compatibility in the regulation of the different pests by service plants, and (2) the compatibility between multi-pest regulation vs disservice mitigation. Our main conclusions are: (1) Despite knowledge gaps, there is good potential of service plants for multi-pest regulation; (2) The challenge lies at least as much to mitigate disservices that service plants may cause as to promote multi-pest regulation; (3) The level of incompatibility between promoting multi-pest regulation vs mitigating disservices varies with the mode of insertion of service plants, increasing with interactions with crop plants. This review shows how a trait-based approach can be used to synthesize knowledge from different disciplines and provides a tool for cross-disciplinary dialogue. It identifies priority research actions that are needed to increase synergy, genericity and adaptation of service plants to local conditions, and provides foundations for the design of service-plant based agroecosystems.
[学术文献 ] Chemical Camouflage in Plants: Defensive Science of Stealth against Insect Herbivory 进入全文
ACS Agricultural Science & Technology 期刊
Chemical camouflage is a fascinating and intricate survival strategy that plants have evolved to defend themselves against herbivores and pests. While plant defense mechanisms have long captivated scientific interest, their full potential remains largely untapped in practical applications. This review takes a distinctive interdisciplinary approach, weaving together insights from molecular biology, ecology, and agricultural science to offer a comprehensive perspective on chemical camouflage. It was driven by a shared understanding that integrating plant defense strategies more deeply into agricultural systems could help address urgent challenges such as pest control, crop productivity, and environmental sustainability. With continued research and advances in biotechnology, chemical camouflage could become a key component of future farming-where crops not only protect themselves but also contribute actively to a more productive and sustainable agricultural landscape.

According to a recent report by Business Research Insights, the global tea market expanded rapidly in 2023, and the market is projected to grow even more by 2029, exhibiting a large compound annual growth rate during the forecast period. North America: The fastest-growing region in the tea market is North America. The United States tea market has been growing exponentially for a number of reasons. In the past year, green, matcha, and herbal blends of tea have attracted a rising number of younger fans. In addition, tea companies are adding new flavors and health supplements to meet the needs of health-conscious customers. RTD tea products has also grown in popularity as people find them easy to carry and consume all day. Thanks to e-commerce, it's now easier for people in the region to buy many different types of tea.
[学术文献 ] Signals from aphid-infested neighboring plants modify aphid performance and host plant biochemistry 进入全文
Journal of Economic Entomology 期刊
This study aims to investigate the effect of HIPVs released by aphid (Brevicoryne brassicae)-infested Brassica napus (emitter) plants on neighboring uninfested conspecific plants (receiver). After 48 h exposure, emitter plants were discarded, and receiver plants were utilized in bioassays to assess aphid performance (fecundity and survival), preference, as well as amino acid and glucosinolates contents of receiver host plants. Results revealed that receiver plants showed a significant reduction in aphid fecundity, although no significant effect on aphid survival was observed. Aphid feeding preference was significantly altered, with B. brassicae showing a reduced preference for receiver plants. Additionally, significant increases in some key amino acids and total concentrations were recorded in receiver plants. Glucosinolates (GSs) analysis showed a significant change in total GS content, with a significant increase in the individual GSs, glucoiberin (GIB), and glucoraphanin (GRA). Current findings provide evidence that receiver plants activate their defence mechanism against B. brassicae by altering amino acid and glucosinolate levels. This study highlights the potential of HIPVs to enhance sustainable pest management strategies.
[学术文献 ] The complex interaction between plants and acoustic signals: friends or foes? 进入全文
The Science of Nature 期刊
Plants exhibit significant alterations in their phenotypes, including in shape, color, and smell, in response to stress.Several signals through which plants communicate with their environment are already known. Plants constantly communicate with each other and their surroundings in order to adjust their morphological and physiological characteristics. During stressful situations, plants release root exudates and different volatile organic compounds (VOCs), which mediate the plant-plant interactions. Like other organisms, plant research has also entered into the world of acoustics, which suggest that plants could also be using sound signals to communicate. However, acoustic vibrations, which act as important cues between plants and their environment, have, to date, not been studied in depth. Importantly, plants sense certain acoustic signals and respond to them accordingly.Vibrations in plants can trigger cellular signaling mechanisms in response to both abiotic and biotic stimuli. When plants are exposed to drought stress, a cavitation process takes place due to air bubbles forming, expanding, and finally rupturing in the lumen of xylem vessels, causing vibrations.A loss of cohesion between water molecules in the volume of xylem conduits (homogenous cavitation) or a loss of adhesion between conduit walls and water (homogeneous cavitation) could be the potential mechanisms for the initiation of cavitation.
