Effect of π-stackings on CP accumulation. a GFP fluorescence and b relative GFP fluorescence intensities in the N. benthamiana leaf patches expressing GFP-TVBMVCP, one of its 16 mutants derived from aromatic residues (F94, W97, Y98, Y105, W122, W136, Y147, F160, F167, Y174, Y184, Y188, Y202, F204, F206 and Y207) that were predicted to form π-stacking, or one of its 3 mutants derived from aromatic residues (F46, Y77 and F237) that could not form π-stacking at 5 dpai. ‘Δ’ indicates the codon for the residue was deleted. The values are the means ± SD from three biological replicates per treatment. Treatments marked with the same lowercase letters have no significant statistical difference
