Summary: The winter oilseed rape planting area in China has expanded to the north, resulting in an increase in cabbage aphids and turnip mosaic virus. The virus infection has both direct and indirect effects on aphid probing behavior, while the influence of plant cultivars on infected plants is not significant.

Summary: Turnip yellows virus (TuYV) is a significant pathogen of oilseed rape, causing substantial yield losses worldwide. This study investigated the resistance of different oilseed rape genotypes to TuYV, using greenhouse and field trials. The genotypes 'DK Temptation' and 'Rescator' were identified as resistant and susceptible models, respectively, and comparisons were made with other genotypes. It was found that certain genotypes exhibited high levels of resistance to TuYV, indicating potential for sustainable crop protection.

Summary: Plant viruses can enhance their transmission efficiency by influencing vector behavior. This comparative study analyzed the effects of turnip mosaic virus (TuMV) infection on the probing behaviors of cabbage aphids on two oilseed rape cultivars. The results showed that infected plants led to increased probing frequencies and modifications in feeding behavior, with differences observed between susceptible and resistant cultivars. Furthermore, the presence of TuMV in aphids directly affected their probing behavior, with viruliferous aphids exhibiting distinct differences in probing activity on an aphid-resistant cultivar. These findings highlight the importance of considering plant cultivar and virus presence in studying virus transmission.

Summary: Contrary to popular belief, the 2X35S promoter actually delayed the initiation of turnip crinkle virus (TCV) infection compared to the Core35S promoter. This suggests that the Core35S (or mini35S) promoter may be a better choice for generating infectious cDNA clones of TCV, as the stronger 2X35S promoter may lead to higher accumulation of a TCV protein that inhibits virus replication.

Summary: The P1 protein in Potyvirus is crucial for viral infection and adaptation, although its exact mechanism is not fully understood. Through yeast-two-hybrid screening, eight potential P1-interacting proteins in Arabidopsis were identified, with NODULIN 19 (NOD19) being selected for further investigation. Further experiments confirmed the interaction between TuMV P1 and NOD19, which is a membrane-associated protein expressed mainly in plant aerial parts. Knockdown of NOD19 in Arabidopsis and soybean resulted in attenuated infection of TuMV and soybean mosaic virus, respectively. These findings suggest that NOD19 is a host factor required for robust viral infection.

Summary: It has been found that TuMV suppresses AA in Brassica rapa leaves, but leaves with high AA are rarely infected. AA serves as a chemical barrier against TuMV. TuMV also inhibits AA induced by high light in Arabidopsis by suppressing the expression of anthocyanin late-biosynthesis genes.

Summary: The ability to construct well-defined three-dimensional architectures at the nanoscale is important for various applications. In this study, functional inorganic nanoparticles were grafted onto viral plant capsids, resulting in advanced hierarchical hybrid nanomaterials with robustness and stability. The virus-based materials showed enhanced heating capability and could potentially be used as photothermal therapeutic agents.

Summary: Research has shown that intercropping with green manure during the oilseed rape season can significantly reduce nitrogen fertilizer application, increase rapeseed yield, and improve nitrogen fertilizer efficiency. Additionally, incorporating green manure can increase soil organic matter content and soil-available nitrogen, reducing reliance on chemical nitrogen fertilizers and enhancing soil quality for increased crop production.

Summary: This study conducted a comprehensive investigation of mosaic diseases and their causal viruses in commercial sugarcane fields in China. The results showed that SrMV had the highest incidence, followed by SCMV and SCSMV, while MaYMV had the lowest incidence. Mixed infections of multiple viruses were also commonly found. This research provides evidence for the development of strategies to prevent and control mosaic diseases in Chinese sugarcane.
