Insight into aphid mediated Potato Virus Y transmission: A molecular to bioinformatics prospective

Abstract

Potato, the world's most popular crop is reported to provide a food source for nearly a billion people. It is prone to a number of biotic stressors that affect yield and quality, out of which Potato Virus Y (PVY) occupies the top position. PVY can be transmitted mechanically and by sap-feeding aphid vectors. The application of insecticide causes an increase in the resistant vector population along with detrimental effects on the environment; genetic resistance and vector-virus control are the two core components for controlling the deadly PVY. Using transcriptomic tools together with differential gene expression and gene discovery, several loci and genes associated with PVY resistance have been widely identified. To combat this virus we must increase our understanding on the molecular response of the PVY-potato plant-aphid interaction and knowledge of genome organization, as well as the function of PVY encoded proteins, genetic diversity, the molecular aspects of PVY transmission by aphids, and transcriptome profiling of PVY infected potato cultivars. Techniques such as molecular and bioinformatics tools can identify and monitor virus transmission. Several studies have been conducted to understand the molecular basis of PVY resistance/susceptibility interactions and their impact on PVY epidemiology by studying the interrelationship between the virus, its vector, and the host plant. This review presents current knowledge of PVY transmission, epidemiology, genome organization, molecular to bioinformatics responses, and its effective management.

“…Soil health stands as the bedrock of terrestrial ecosystems, serving as a vital foundation for agricultural productivity, ecological stability, and the sustenance of diverse life forms [1]. Within this intricate web of soil dynamics, the role of soildwelling insects emerges as an integral component, orchestrating a delicate balance in the ecosystem [2][3][4]. In recent years, the integration of biochar as a soil amendment has garnered considerable attention for its potential to revolutionize soil health and agricultural sustainability [5,6].…”

Potato Virus Y and Shallot Latent Virus of Kajoran Horticultural Production Center, Magelang Regency, Indonesia: Molecular Characterization Case Study

“…However, most of the symptomatic samples that were taken to laboratory were infected with viruses. The population of aphids, the insect vector of both PVY and SLV (Bhoi et al, 2022;Lou et al, 2023), was observed to be low, likely due to routine insecticide application. The two viruses are also transmitted through vegetative propagation, the main means of potato and shallot transplantation.…”

“…The two viruses are also transmitted through vegetative propagation, the main means of potato and shallot transplantation. While SLV is mostly confined to Allium spp., PVY is spreadable among a wide host range (Mansouri et al, 2021;Bhoi et al, 2022). These showed that viral diseases are potentially still hindering crop production in the area.…”

Effects of meteorological variables on potato leaf roll virus and potato virus y infections on different potato varieties under natural and mulched conditions

“…Due to the PLRV's high occurrence, it became an emerging disease in Pakistan (Batool et al, 2011). The 5 th most dangerous plant virus, PVY, belongs to the family Potyviridae and contains an economically vital group of plant viruses (Bhoi et al, 2022). Worldwide and in Pakistan damages are up to 85% when the crop is developed from infected tubers (Thomas-Sharma et al, 2016).…”
