Abstract

Plants are central to global food production, and the pursuit of sustainability aims to enhance or preserve food quality while safeguarding the environment. Due to their immobility, plants are unable to evade unfavourable climatic setups or interactions with other living creatures. Upon their interaction with insect herbivores, plants face biotic stress, which is a constant challenge for plants, causing molecular, physiological, and biochemical changes and reducing their productivity. To combat biotic stress caused by herbivores, plants have evolved intricate defence mechanisms through growth regulators such as auxins, cytokinins, gibberellins, salicylic acid (SA), jasmonic acid (JA), ethylene (ET), abscisic acid (ABA), strigolactones and brassinosteroids. The intricate network of specific proteins, metabolites and certain phytohormones orchestrates plant defensive reactions, leading to their skilful coordination in responding to insect attacks. Comprehending the defence mechanisms holds the key to mitigating significant crop and economic losses. This review entails a comprehensive analysis of the role of growth regulators in enhancing plant immunity against herbivory, highlighting the substantial efforts by the scientific community to manage and mitigate damages from biotic stress in plants, ultimately contributing to the advancement of sustainable agriculture.

解密生长调节剂在增强植物免疫力对抗食草动物方面的作用。

植物是全球粮食生产的核心，追求可持续发展的目的是在保护环境的同时提高或保持粮食质量。由于植物的不可动性，它们无法躲避不利的气候环境或与其他生物的相互作用。在与昆虫食草动物相互作用时，植物会面临生物压力，这对植物来说是一个持续的挑战，会引起分子、生理和生化变化，降低植物的生产力。为了应对食草动物造成的生物胁迫，植物通过生长调节剂（如辅酶、细胞分裂素、赤霉素、水杨酸（SA）、茉莉酸（JA）、乙烯（ET）、脱落酸（ABA）、糙叶内酯和铜皮类固醇）进化出了复杂的防御机制。由特定蛋白质、代谢物和某些植物激素组成的错综复杂的网络协调了植物的防御反应，使它们能够娴熟地协调应对昆虫的攻击。了解防御机制是减轻重大作物和经济损失的关键。这篇综述全面分析了生长调节剂在增强植物免疫力以抵御草食动物侵害方面的作用，突出了科学界在管理和减轻植物生物胁迫造成的损害方面所做的大量努力，最终促进了可持续农业的发展。

期刊介绍： Physiologia Plantarum is an international journal committed to publishing the best full-length original research papers that advance our understanding of primary mechanisms of plant development, growth and productivity as well as plant interactions with the biotic and abiotic environment. All organisational levels of experimental plant biology – from molecular and cell biology, biochemistry and biophysics to ecophysiology and global change biology – fall within the scope of the journal. The content is distributed between 5 main subject areas supervised by Subject Editors specialised in the respective domain: (1) biochemistry and metabolism, (2) ecophysiology, stress and adaptation, (3) uptake, transport and assimilation, (4) development, growth and differentiation, (5) photobiology and photosynthesis.
