Sri Lankan cassava mosaic virus (SLCMV) symptoms severity score by visual detection in wild-type and transgenic plants.

aThree plants were tested per transgenic line.bData represent the sum for the three plants tested and were recorded at 45 days post inoculation.cDisease indices were calculated using the equation shown in materials and methods.Disease rating is based on the calculated disease indices. Symptom severity score, the intensity of the disease on the leaf is expressed on a scale of 0–3 grades (0, no symptom; 1, mild/faint mosaic symptoms; 2, moderate mosaic symptoms; 3, severe mosaic symptoms, as shown in Fig. 7). Plants with a disease index of 0% were considered as immune, those with a disease index NA not applicable, WT wild-type plant, MC mock inoculated control plant, K3-K10 transgenic cassava lines expressing hairpin SLCMV.Sri Lankan cassava mosaic virus (SLCMV) symptoms severity score by visual detection in wild-type and transgenic plants.
