Bunchy top J-hook symptom

Caption:: The so-called 'J-hook' symptom consists in dark green streaks that run along the veins and terminate at the midrib in the distinctive pattern after which it is named. Green J-hooks are often associated with the 'morse code' symptom of dark streaks of different lengths. These symptoms are reliable indicators of bunchy top, a devastating disease caused by the Banana bunchy top virus (BBTV).
