Metagenomics-based novel Caulimoviridae virus discovery and its development of identification markers in Lilium lancifolium thunb.

ABSTRACT: Plant viruses cause considerable economic losses in the lily industry due to the emergence of diverse viral mutations and novel pathogens. Effective detection and identification of these viruses are critical for controlling their spread and mitigating infections. In this study, two novel Caulimoviridae viruses, namely Lancifolium Caulimovirus A (LCaA) and Lancifolium Caulimovirus B (LCaB), were identified for the first time in Lilium lancifolium Thunb. (tiger lily) through integrated metagenomic sequencing and Sanger sequencing. The complete genomes of LCaA and LCaB were determined to be 7,542 nt and 7,582 nt in length, respectively. Among the pooled tiger lily samples, seven LCaA isolates exhibited genome sequence identities ranging from 99.59 to 99.73%, while six LCaB isolates showed ide
