AI Article Synopsis

  • Cucumber mosaic virus (CMV) has been increasingly found in zucchini crops across Poland, showing both typical and new necrotic isolates.
  • Analysis of 27 CMV isolates from different regions showed they belong to two main subgroups: IA and II, with subgroup II being the most common.
  • Additionally, researchers identified new recombinant variants that exhibit a genetic pattern of IA-MP/II-CP in RNA3.

Article Abstract

In recent years, the occurrence of cucumber mosaic virus (CMV) has been noted in zucchini crops in Poland. Beside characteristic isolates, which displayed mosaics and chlorosis on infected plants, new necrotic isolates have also been identified. Here, we analysed the molecular variability of 27 isolates of CMV collected from zucchini in various regions of the country. Sequence and phylogenetic analysis based on the genes encoding the coat (CP) and movement (MP) proteins revealed that the Polish isolates belong to two subgroups: IA and II, with the prevalence of subgroup II. New recombinant variants with an IA-MP/II-CP pattern for RNA3 were also detected.

Changes in critical sites of virus-encoded protein or cis-acting element generally determine pathogenicity differentiation among different isolates of the same plant virus. Cucumber mosaic virus (CMV) isolates, which exhibit the most extensively known host range, demonstrate notable pathogenicity differentiation. This study focuses on the severe isolate CMV and mild isolate CMV, both affecting several species within the Solanaceae family, to identify the key factors regulating pathogenicity differentiation.

Paris yunnanensis, also named as Rhizoma Paridis in the Chinese Pharmacopeia, is a perennial Chinese medicinal herb commonly grown in Southwest China. However, several viruses have been found infecting this plant in recent years. Using high-throughput sequencing (HTS) and Sanger sequencing, this study obtained the complete genome sequences of three capillovirus isolates and one potyvirus isolate.

Plant viruses have evolved different viral suppressors of RNA silencing (VSRs) to counteract RNA silencing which is a small RNA-mediated sequence-specific RNA degradation mechanism. Previous studies have already shown that the coat protein (CP) of cucumber mosaic virus (CMV) reduced RNA silencing suppression (RSS) activity of the VSR of CMV, the 2b protein. To demonstrate the universality of this CP-VSR interference, our study included three different viruses: CMV and peanut stunt virus (PSV) from the Bromoviridae, and plum pox virus (PPV) from the Potyviridae family.

Virus-induced gene silencing (VIGS) represents a particularly relevant tool in agricultural species for studying gene functionality. This study presents a novel approach for utilizing viruses belonging to the 30K family of movement proteins (MPs) as VIGS vectors. The method described here employs smaller inserts (54 bp or less) than those commonly used (100-500 bp).
