Table 1 Summary of the results of the infectivity studies

From: Reactions of Nicotiana species to inoculation with monopartite and bipartite begomoviruses

Species (ploidy level, chromosome number) Parents Origin Infectivity of ToLCNDV (plants symptomatic/plants inoculated) Plants PCR positive for ToLCNDV with primers ToLCNDVV2F/ToLCNDVV2R Infectivity of CLCuMV (plants symptomatic/plants inoculated) Plants PCR positive for CLCuMV with primers PK3AV2F/PK3AV2R Plants PCR positive for CLCuMV with primers BegomoF/BegomoR
N. sylvestris (2x = 24) - South America 4/4 4 0/4 0 0 (0.7)*
N. obtusifolia (2x = 24) - Southwestern USA, Mexico 0/4 0 0/4 0 0 (1.4)*
N. benthamiana (4x = 38) N. sylvestris (likely maternal parent) Australia 4/4 4 4/4 4 4 (2.8)*
N. suaveolens (4x = 32) N. sylvestris (likely maternal parent) Australia 0/4 0 0/4 0 0
N. tabacum (4x = 48) N. tomentosiformis, N. sylvestris Eastern North America 4/4 4 0/4 4 4 (2.8)*
