Résumé
In previous work, RNA-seq was applied to identify the causal agent of yellow leaf disease (YLD) in areca palm (Areca catechu L.), resulting in the identification of areca palm velarivirus 1 (APV1) associated with YLD. Additionally, RNA-seq revealed a totivirus-like virus in areca palm. This work revealed that the totivirus-like virus is prevalent in asymptomatic areca palms. Therefore, it was tentatively named "areca palm latent totivirus 1" (APLTV1). The complete genome sequence of APLTV1 was determined and found to be 4754 base pairs (bp) in length, containing two ORFs whose encoded proteins share 55% and 69% amino acid (aa) sequence identity with the capsid protein (CP) and RNA-dependent RNA polymerase (RdRp), respectively, of Bursera graveolens-associated totivirus 1 (BgAT1). Phylogenetic analysis based on alignment of the CP and RdRp sequences revealed that APLTV1 clustered with other members of the genus Totivirus, suggesting that APLTV1 represents a novel species of the genus Totivirus, family Totiviridae.
