A new endornavirus species infecting Malabar spinach (Basella alba L.)
Abstract:
A putative new endornavirus was isolated from Malabar spinach (Basella alba). The viral dsRNA consisted of 14,027 nt with a single ORF that coded for a polyprotein of 4,508 aa. The genome organization was similar to that of four other endornaviruses. Conserved domains for helicase-1, capsular synthase, UDP-glucose-glycosyltransferase (UGT), and RdRp were detected. Infected plants were phenotypically undistinguishable from healthy ones. The name Basella alba endornavirus is proposed for the virus isolated from Malabar spinach.
