Overview

Molecular analysis reveals natural infection of cowpea mild mottle virus in Salvia miltiorrhiza crops, highlighting an expanded host range for the plant pathogen.

Key Points

  • To identify and characterize the viral pathogen causing mosaic, mottle, and chlorosis symptoms in cultivated Salvia miltiorrhiza in Henan province, China.
  • Surveyed six cultivation areas in Henan province using a five-point sampling method and collected symptomatic leaf samples (N=7).
  • Constructed a pooled library for high-throughput sequencing on the Illumina NovaSeq 6000 platform and validated viral presence through RT-PCR, Sanger sequencing, and overlapping fragment amplification.
  • Field surveys demonstrated an average viral disease incidence of 71% across the sampled Salvia miltiorrhiza cultivation areas.
  • High-throughput sequencing assembled nine contigs mapping to cowpea mild mottle virus (CPMMV) with 97.87% to 100% nucleotide identity, confirmed in all seven samples via RT-PCR of an 840 bp coat protein gene.
  • Assembled the nearly complete 8,200 nt genome of the CPMMV-Sm5 isolate, which shared 98.99% nucleotide identity and clustered phylogenetically with the Chinese Fabaceae isolate CPMMV-HN-SQ.
