Plant viruses transmitted by arthropods, as an important biotic factor, may not only directly affect the yield and quality of host plants, and development, physiological characteristics and ecological performances of their vector arthropods, but also directly or indirectly affect the non-vector herbivorous arthropods and their natural enemies in the same ecosystem, thereby causing influences to the whole agro-ecosystem. This paper reviewed the progress on the effects of plant viruses on herbivorous arthropods, including vector and non-vector, and their natural enemies, and on their ecological mechanisms to provide a reference for optimizing the management of vector and non-vector arthropod populations and sustainable control of plant viruses in agro-ecosystem.

Winter barley (Hordeum vulgare) production areas in the middle and lower reaches of the Yangtze River are severely threatened by barley yellow mosaic disease, which is caused by Barley yellow mosaic virus and Barley mild mosaic virus. Improving barley disease resistance in breeding programs requires knowledge of genetic loci in germplasm resources. In this study, bulked segregant analysis (BSA) identified a novel major quantitative trait loci (QTL) QRym.

Agrobacterium-mediated gene transformation method is a vital molecular biology technique employed to develop transgenic plants. Plants are genetically engineered to develop disease-free varieties, knock out unsettling traits for crop improvement, or incorporate an antigenic protein to make the plant a green factory for edible vaccines. The method's robustness was validated through successful transformations, demonstrating its effectiveness as a standard approach for researchers working in plant biotechnology.

Transient expression in Tobacco is a popular way to produce recombinant proteins in plants. The design of various expression vectors, delivered into the plant by , has enabled high production levels of some proteins. To further enhance expression, researchers often adapt the coding sequence of heterologous genes to the host, but this strategy has produced mixed results in Tobacco.

Forty-four samples of garlic plants showing virus-like symptoms were collected, during the growing season (2021-2022) from different locations in Qassim province, Saudi Arabia. These samples were analyzed by ELISA against the important Allium allexiviruses including garlic virus A (GarV-A), garlic virus B (GarV-B), garlic virus C (GarV-C), and Shallot virus X (ShVX). The obtained results showed that 22/44 (50%) samples were found to be infected with one of the tested viruses.

The size of viral genomes is limited, thus the majority of encoded proteins possess multiple functions. The main function of tobamoviral movement protein (MP) is to perform plasmodesmata gating and mediate intercellular transport of the viral RNA. MP is a remarkable example of a protein that, in addition to the initially discovered and most obvious function, carries out numerous activities that are important both for the manifestation of its key function and for successful and productive infection in general.
