Ultraviolet-B radiation (UVB; 280-315 nm) is a significant environmental factor that alters plant development, changes interactions between species, and reduces the prevalence of pests and diseases. While UVB radiation has negative effects on plant growth and performance at higher doses, at lower and ambient doses, UVB radiation acts as a non-chemical method for managing biotic stresses by having positive effects on disease resistance and genes that protect plants from pests. Understanding the recent relationship between UVB radiation and plants' biotic stresses is crucial for the development of crops that are resistant to UVB and biotic stresses. However, little is known about the recent interactions between UVB radiation and biotic stresses in plants. This review discusses the most recent connections between UVB radiation and biotic stresses in crops, including how UVB radiation affects a plant's resistance to disease and pests. The interaction of UVB radiation with pathogens and herbivores has been the subject of the most extensive research of these. This review also discusses additional potential strategies for conferring multiple UVB-biotic stress resistance in crop plants, such as controlling growth inhibition, miRNA 396 and 398 modulations, and MAP kinase. This study provides crucial knowledge and methods for scientists looking to develop multiple resistant crops that will improve global food security.
紫外线-B 辐射(UVB;280-315nm)是一种重要的环境因素,它改变植物的发育、改变物种之间的相互作用,并降低病虫害的流行率。虽然在较高剂量下,紫外线-B 辐射对植物生长和性能有负面影响,但在较低和环境剂量下,紫外线-B 辐射通过对疾病抗性和保护植物免受害虫侵害的基因产生积极影响,成为管理生物胁迫的非化学方法。了解紫外线-B 辐射与植物生物胁迫之间的最新关系对于开发耐紫外线-B 和生物胁迫的作物至关重要。然而,人们对紫外线-B 辐射和植物生物胁迫之间最近的相互作用知之甚少。本综述讨论了紫外线-B 辐射与作物中生物胁迫之间的最新联系,包括紫外线-B 辐射如何影响植物对疾病和害虫的抗性。紫外线-B 辐射与病原体和草食动物的相互作用是这些研究中最广泛的研究主题。本综述还讨论了在作物中赋予多种紫外线-生物胁迫抗性的其他潜在策略,例如控制生长抑制、miRNA396 和 398 调节以及 MAP 激酶。这项研究为希望开发提高全球粮食安全的多种抗性作物的科学家提供了关键的知识和方法。
