[学术文献 ] The role of methyl salicylate in plant growth under stress conditions 进入全文
Journal of Plant Physiology 期刊
Methyl salicylate is a volatile compound, the synthesis of which takes place via the salicylic acid pathway in plants. Both compounds can be involved in the development of systemic acquired resistance and they play their role partly independently. Salicylic acid transport has an important role in long-distance signalling, but methyl salicylate has also been suggested as a phloem-based mobile signal, which can be demethylated to form salicylic acid, inducing the de-novo synthesis of salicylic acid in distal tissue. Despite the fact that salicylic acid has a protective role in abiotic stress responses and tolerance, very few investigations have been reported on the similar effects of methyl salicylate. In addition, as salicylic acid and methyl salicylate are often treated simply as the volatile and non-volatile forms of the same compound, and in several cases they also act in the same way, it is hard to highlight the differences in their mode of action. The main aim of the present review is to reveal the individual role and action mechanism of methyl salicylate in systemic acquired resistance, plant-plant communication and various stress conditions in fruits and plants.

[学术文献 ] Plant Secondary Metabolites as Defense Tools against Herbivores for Sustainable Crop Protection 进入全文
International Journal of Molecular Sciences 期刊
Plants have evolved several adaptive strategies through physiological changes in response to herbivore attacks. Plant secondary metabolites (PSMs) are synthesized to provide defensive functions and regulate defense signaling pathways to safeguard plants against herbivores. Herbivore injury initiates complex reactions which ultimately lead to synthesis and accumulation of PSMs. The biosynthesis of these metabolites is regulated by the interplay of signaling molecules comprising phytohormones. Plant volatile metabolites are released upon herbivore attack and are capable of directly inducing or priming hormonal defense signaling pathways. Secondary metabolites enable plants to quickly detect herbivore attacks and respond in a timely way in a rapidly changing scenario of pest and environment. PSMs modulate multi-trophic interactions involving host plants, herbivores, natural enemies and pollinators. Although the role of secondary metabolites in plant-pollinator interplay has been little explored, several reports suggest that both plants and pollinators are mutually benefited. Molecular insights into the regulatory proteins and genes involved in the biosynthesis of secondary metabolites will pave the way for the metabolic engineering of biosynthetic pathway intermediates for improving plant tolerance to herbivores. This review throws light on the role of PSMs in modulating multi-trophic interactions, contributing to the knowledge of plant-herbivore interactions to enable their management in an eco-friendly and sustainable manner.

SpringerLink 网站
This book provides an overview of the recent advancements for plant scientists with a research focus on phytohormones and their responses (nature, occurrence, and functions) in plant cells. This book focuses on the role of phytohormones in biosynthesis, plant sexual reproduction, seed germination and fruit development and ripening. It further highlights the roles of different phytohormones on signaling pathways as well as on photoperiodism/Gravitropism/Thigmotropism.The volume also explores the role of phytohormones in gene expression and plant melatonin and serotonin and covers how plant hormones react in case of stress/defence response (metals/metalloids/pathogen). Last but not least, this volume also discusses phytohormones in the context of new regulatory molecules such as Nitric oxide, hydrogen sulfide, melatonin.
[学术文献 ] Plant Growth Promoting Rhizobacteria (PGPR) induced protection: A plant immunity perspective 进入全文
Physiologia Plantarum 期刊
Plant-environment interactions, particularly biotic stress, are increasingly essential for global food security due to crop losses in the dynamic environment. Therefore, understanding plant responses to biotic stress is vital to mitigate damage. Beneficial microorganisms and their association with plants can reduce the damage associated with plant pathogens. One such group is PGPR (Plant growth-promoting rhizobacteria), which influences plant immunity significantly by interacting with biotic stress factors and plant signalling compounds. This review explores the types, metabolism, and mechanisms of action of PGPR, including their enzyme pathways and the signalling compounds secreted by PGPR that modulate gene and protein expression during plant defence. Furthermore, the review will delve into the crosstalk between PGPR and other plant growth regulators and signalling compounds, elucidating the physiological, biochemical, and molecular insights into PGPR's impact on plants under multiple biotic stresses, including interactions with fungi, bacteria, and viruses. Overall, the review comprehensively adds to our knowledge about PGPR's role in plant immunity and its application for agricultural resilience and food security.
[学术文献 ] Release patterns and potential utility of herbivore-induced plant volatiles in crops: A review 进入全文
Environmental and Experimental Botany 期刊
Herbivore-induced plant volatiles (HIPVs) are synthesized and released from damaged plants, playing a critical role in the interactions among plants, herbivorous pests, and their natural enemies. Recent research has focused on the regularity in the synthesis and release patterns of certain HIPVs, which are consistent with the behaviors of herbivores or their natural enemies. However, their instability has prevented the widespread use of HIPVs for crop protection. In this review, we summarize the current knowledge regarding the regular patterns of HIPVs synthesis and release, including the associated regulatory mechanisms and influence of endogenous/environmental factors. We also describe the potential utility of HIPVs for enhancing agricultural production. The information provided herein will help researchers better understand the functions and ecological significance of HIPVs, which may lead to the development of viable methods for monitoring and detecting agricultural pests and diseases, with implications for pest and disease control.
