Identification of a new pathotype of Bean yellow mosaic virus (BYMV) infecting blue passion flower and some evolutionary characteristics of BYMV

Identification of a new pathotype of Bean yellow mosaic virus (BYMV) infecting blue passion... The modes of molecular evolution of the coat protein (CP) and 3′ non-coding region (NCR) were investigated in Bean yellow mosaic virus (BYMV) isolates, including a new pathotype from blue passion fruit. In phylogenetic analysis, the new pathotype did not cluster with pathotypes or host groups described previously. Intraspecific recombinations involving the entire 3′-NCR and a variable portion of the 3′-terminal region of the CP gene were detected between a broad bean isolate and several isolates from monocots. Since the predicted secondary structure of the 3′-NCR correlated mostly with the botanical origin of isolates, a possible role of the 3′-NCR in BYMV host adaptation is proposed and discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals

Abstract

The modes of molecular evolution of the coat protein (CP) and 3′ non-coding region (NCR) were investigated in Bean yellow mosaic virus (BYMV) isolates, including a new pathotype from blue passion fruit. In phylogenetic analysis, the new pathotype did not cluster with pathotypes or host groups described previously. Intraspecific recombinations involving the entire 3′-NCR and a variable portion of the 3′-terminal region of the CP gene were detected between a broad bean isolate and several isolates from monocots. Since the predicted secondary structure of the 3′-NCR correlated mostly with the botanical origin of isolates, a possible role of the 3′-NCR in BYMV host adaptation is proposed and discussed.
