摘要：
Orchids are some of the most important ornamental flowers. Cymbidium mosaic virus (CymMV) and Odontoglossum ringspot virus (ORSV) are the most prevalent and economically important viruses affecting orchids in China. In this study, 20 CymMV and 28 ORSV isolates were selected for genetic diversity analysis. The CymMV isolates shared 84.6-100% and 89.5-100% identities of coat protein (CP) at the nucleotide (nt) and amino acid (aa) levels, respectively. The identities of ORSV isolates were 96.4-100% (nt) and 92.5-99.4% (aa). The CP genes of CymMV were found to have genetic diversity, and the CP genes of ORSV were genetically conservative. These results can aid in designing effective disease-control strategies.
