Infectivity of amino acid 143 position point mutant clones of coat protein of ToLCNDV. (A) Phenotype of point mutant constructs (ES-V1W143R: the residue tryptophan at amino acid 143 was changed to arginine in ToLCNDV-ES CP and In-V1R143W: arginine was changed to tryptophan in ToLCNDV-In CP) in tomato. (B, C) Sampling position and PCR results in different tissues, Lane M: positive control, Lane −: negative control, Lane C: mock plant, NL, new leaf; S, stem; R, root. (D) Relative viral titer in different tissues. The bar graph indicate the mean ± standard deviation (n = 3). The statistical comparison was performed with the unpaired t-test: *p <0.05, ns, not significant.
