In Clustal analysis, sequences of HSVd-bn1 and HSVd-bn2 aligned with other HSVd variants showing nearly 100% sequence identity with HSVd-cit 6 (GQ246199) isolated from Clementine mandarin on Carrizo citrange (Banihashemian et al., 2010), but with comparatively lower homologies with many other HSVd variants including those associated with gummy and split bark and as well with yellow corky vein of citrus (Table 2).
