Abstract

Tapping panel dryness (TPD) disease is the most economically important malady affecting the quality and quantity of yield of rubber latex. The etiological agent of the disease has not yet been characterized. In the present communication, we report the association of a viroid belonging to potato spindle tuber viroid group (PSTVd). The isolates cloned from TPD-affected rubber samples and tomato leaves infected by the extract from TPD-affected rubber showed more than 95% identity with PSTVd.
