Resistance Management through Brassica Crop–TuMV–Aphid Interactions: Retrospect and Prospects

Abstract

Turnip mosaic virus (TuMV) is an important threat to the yield and quality of brassica crops in China, and has brought serious losses to brassica crops in the Far East, including China and the north. Aphids (Hemiptera, Aphidoidea) are the main mediators of TuMV transmission in field production, and not only have strong virus transmission ability (small individuals, strong concealment, and strong fecundity), but are also influenced by the environment, making them difficult to control. Till now, there have been few studies on the resistance to aphids in brassica crops, which depended mainly on pesticide control in agriculture production. However, the control effect was temporarily effective, which also brought environmental pollution, pesticide residues in food products, and destroyed the ecological balance. This study reviews the relationship among brassica crop–TuMV, TuMV–aphid, and brassica crop–aphid interactions, and reveals the influence factors (light, temperature, and CO2 concentration) on brassica crop–TuMV–aphid interactions, summarizing the current research status and main scientific problems about brassica crop–TuMV–aphid interactions. It may provide theoretical guidance for opening up new ways of aphid and TuMV management in brassica crops.

Aphids on Aphid-Susceptible Cultivars Have Easy Access to Turnip Mosaic Virus, and Effective Inoculation on Aphid-Resistant Cultivars of Oilseed Rape (Brassica napus)

“…Visual cues emanating from virus-infected plants make the plants more apparent to their vectors [ 5 ]. After TuMV infection of brassica crops, the veins in the plant’ s new leaves became increasingly obvious and gradually turned into mottled leaves, and the leaves shrank and grew slowly [ 25 ]. However, the occurrence of TuMV infection hardly correlates with leaf color [ 42 ].…”

“…Similarly, green peach aphids preferred tobacco infected with TuMV and had higher fecundity on tobacco and A. thaliana infected with TuMV [ 44 ]. The plants, after being inoculated with TuMV, could release VOCs which may attract the aphids to feed the plants and transmit the TuMV to new plants [ 5 , 25 ]. In a study of the interaction between TuMV-transmitting aphids and brassica crops, brassica crops produce some chemical volatiles to regulate the behavior of aphids.…”

“…As a result, the cultivation and promotion of resistance cultivars are one of the most cost-effective and effective measures for preventing and controlling TuMV. Further elucidating the interactions of the three species (oilseed rape–TuMV–cabbage aphid) could not only aid in understanding the mechanism of species formation and constructing the co-evolution model among insects, TuMV, and plants but also in coordinating the relationship between plant resistance and biological control in production, which would provide theoretical guidance for opening up new methods for aphid and TuMV management [ 25 ].…”

“…CMV and TuMV are naturally transmitted by aphids (Hemiptera, Aphidoidea) in a non-persistent manner. At least 89 species of aphids are efficient vectors for TuMV and 80 species for CMV (Sevik 2017, Lu et al 2022.…”

Integrative systems biology analysis of barley transcriptome ─ hormonal signaling against biotic stress

“…Today, large-scale data generated from functional genomic studies on plant-pathogen interactions have provided massive information [ 15 ]. Therefore, access to OMICS information on the behavior of defense genes against pathogens helps to decipher the gene networks that led to the identification of pathogen specific-responses [ 16 ]. In recent years, computational systems biology has collected exquisite opportunities to dominate biological complexity [ 17 , 18 ].…”
