摘要

植物病毒对全球构成重大挑战，因为它们严重危害多种作物，并显著降低其质量和产量。这些病毒改变受感染植物的生理、分子和生化过程。番茄花叶病毒（ToMV）是影响番茄种植最广泛和最具破坏性的病毒之一。本研究旨在利用番茄叶片的水提物和菊苣叶的水提物作为生物防治剂，保护番茄植株免受ToMV感染。此外，还评估了两种提取物对病毒症状、植物生长和受感染植物叶片中ToMV积累的影响。两种提取物诱导系统获得性抗ToMV的有效性及其对防御相关基因转录水平的影响与类黄酮生物合成途径有关。这些酶包括查尔酮合成酶（CHS）、查尔酮异构酶（CHI）、肉桂酸-4-羟化酶（C4H）、黄酮3-羟化酶（F3H）和二氢黄酮醇还原酶（DFR）。此外，用提取物处理番茄组织中茉莉酸信号通路基因JEFR、GST1、WRKY1和WRKY19。同样，JEFR、GST1、WRKY1和WRKY19也用植物提取物处理。综上所述，在病毒性疾病流行的情况下，松鸡和菊苣提取物是降低ToMV感染、增强植物健康和提高农业产量的有效途径。

Using Sonchus oleraceus and Cichorium intybus extracts to enhance antiviral defense genes and trigger physiological parameters in tomato plants against tomato mosaic virus

Plant viruses pose a significant global challenge, as they severely harm a wide range of crops and significantly reduce their quality and yield. These viruses change the physiological, molecular, and biochemical processes of infected plants. Tomato mosaic virus (ToMV) is recognized as one of the most widespread and destructive viruses impacting tomato cultivation globally. The current study aimed to protect tomato plants from ToMV infection by using the aqueous extracts from leaves of Sonchus oleraceus and Cichorium intybus as biocontrol agents. Additionally, the effects of both extracts on viral symptoms, plant growth, and ToMV accumulation in infected plant leaves were evaluated. The effectiveness of both extracts in inducing systemic acquired resistance against ToMV and their effects on the transcriptional levels of defense-related genes are associated with the flavonoid biosynthetic pathway. These include chalcone synthase (CHS), chalcone isomerase (CHI), cinnamate-4-hydroxylase (C4H), flavanone 3-hydroxylase (F3H), and dihydroflavonol reductase (DFR). In addition, jasmonic acid signaling pathway genes, such as JEFR, GST1, WRKY1, and WRKY19, in tomato tissues were treated with extracts. Likewise, JEFR, GST1, WRKY1, and WRKY19 were treated with the plant extracts as well. In summary, when viral diseases are prevalent, extracts from Sonchus oleraceus and Cichorium intybus stand out as an effective way to lower ToMV infections, enhance plant health, and increase agricultural production.

期刊介绍： Physiological and Molecular Plant Pathology provides an International forum for original research papers, reviews, and commentaries on all aspects of the molecular biology, biochemistry, physiology, histology and cytology, genetics and evolution of plant-microbe interactions. Papers on all kinds of infective pathogen, including viruses, prokaryotes, fungi, and nematodes, as well as mutualistic organisms such as Rhizobium and mycorrhyzal fungi, are acceptable as long as they have a bearing on the interaction between pathogen and plant.
