Further comparison of the vascular bundle sheath sclerenchyma cell deterioration in separate plants infected with an additional four CTV isolates, CTV-2, T-TX8, T-TX9 and T-TX24 showed that there were significant differences in scleranchyma cell deterioration in principal lateral vein, midvein, petiole, and healthy control with all four CTV isolates (P=0.000 1, F=80.60, df= 47). Healthy plants had no such sclerenchyma cell deterioration.
