Identify the viral agents responsible for widespread leaf yellowing, vein clearing, and mosaic symptoms in commercial chili pepper crops.
Collected 20 symptomatic leaf samples across two commercial chili pepper (Capsicum annuum) fields for pooled RNA sequencing on an Illumina NovaSeq 6000 platform.
Performed de novo transcriptome assembly using Trinity and identified viral sequences via BLAST analyses.
Determined terminal sequences using 5′ and 3′ RACE assays and validated individual samples (N=20) via specific RT-PCR, Sanger sequencing, and dot blot hybridization.
Assembled a 3,001-nt complete sequence of PeVYVaRNA (isolate PeVYVaRNA-CJ), sharing 96.5% nucleotide identity with a South African reference isolate.
Detected PeVYVaRNA and pepper vein yellows virus 5 (PeVYV-5) concurrently in 16 of the 20 (80%) tested field samples.
Identified complex mixed infections comprising cucumber mosaic virus, chilli veinal mottle virus, pepper yellow leaf curl Indonesia virus, and pepper cryptic virus 2.
