2015, VirologyCitation Excerpt :These results suggest that the tested TYLCV-Is V2 mutants have difficulty proliferating, as the reduced DNA-accumulation levels in the V2 mutants were tenfold lower than those of the wt virus. This is in agreement with previous studies (Padidam et al., 1996; Rigden et al., 1993; Wartig et al., 1997). The two TYLCV-Is V2 mutants did not differ in their DNA-accumulation levels in infected plants, indicating that mutations abolishing the suppression of RNA silencing (C84S/C86S) are equivalent in their effect on virus accumulation to a mutation that totally abolishes V2 expression (E8te).
Effects of the mutation of selected genes of Cotton leaf curl Kokhran virus on infectivity, symptoms and the maintenance of Cotton leaf curl Multan betasatellite
2012, Virus ResearchCitation Excerpt :However, infections did not induce symptoms and were associated with very low viral DNA levels. This is consistent with earlier mutational analyses of monopartite begomoviruses (Rigden et al., 1993; Wartig et al., 1997) and suggests that the V2 protein is involved in virus movement. The expression of V2 from a Potato virus X (PVX) vector resulted in severe leaf curling and suggests a role for V2 in symptom induction (Mubin et al., 2010).
