TL;DR
This study identifies and analyzes viruses in 15 Korean peanut cultivars, revealing the prevalence and genetic diversity of several viral species.
Contribution
The study provides a comprehensive virome analysis of Korean peanut cultivars and reports on the genetic diversity of key viruses.
Findings
Cucumber mosaic virus (CMV) was the most prevalent virus across the peanut cultivars.
Genetic diversity was observed in bean common mosaic virus (BCMV) through SNP analysis.
Complete genomes of BCMV, PeMoV, BrYV, and CMV segments were assembled for phylogenetic analysis.
Abstract
This study explores the virome of fifteen peanut cultivars in Korea. Through RNA sequencing, 305 viral contigs associated with cucumber mosaic virus (CMV), peanut mottle virus (PeMoV), bean common mosaic virus (BCMV), and brassica yellows virus (BrYV) were identified, with CMV notably prevalent across samples. Evaluation of viral abundance using viral reads and TPM values revealed CMV dominance in reads and PeMoV prominence in normalized values in select samples. Complete genomes of BCMV, PeMoV, BrYV, and CMV segments were assembled, enabling phylogenetic analysis that uncovered genetic relationships among viral isolates. RT-PCR confirmed BCMV, CMV, and PeMoV presence. Genetic diversity within BCMV was evident through single-nucleotide polymorphism (SNP) analysis, displaying diverse patterns and correlations with viral reads. This study discusses the implications for peanut cultivation,…
