Identification of a novel mild isolate of areca palm necrotic spindle-spot virus (ANSSVm) lacking two cysteine proteases (HC-Pro1 and HC-Pro2)

Areca palm necrotic spindle-spot virus (ANSSV) encodes two tandem cysteine proteases, HC-Pro1 and HC-Pro2, at its N-terminal region, essential for maintaining viral infectivity. Deletion of either protease from an infectious clone abolishes infectivity. We report a mild ANSSV isolate, designated ANS...
