Overview

Identifies viroid diversity and pathogenic determinants in citrus, revealing implications for crop management.

Key Points

  • The aim is to explore the diversity, genetic traits, and host interactions of citrus viroids in northeastern Argentina.
  • Collected Citrus sinensis samples from three subregions
  • Inoculated symptomatic material into Etrog citron for analysis
  • Conducted molecular identification and accumulation studies
  • Inoculated selected isolates into various host plants to assess pathogenicity
  • CEVd, HSVd, and CDVd identified in varying infection rates: 15% CEVd alone, 50% HSVd and CDVd, 35% triple infections
  • CEVd grouped into severe and mild strains with distinct accumulation patterns
  • HSVd variants caused growth delay in cucumber but were non-cachexia
  • In silico analysis found significant host gene target associations for symptom expression
