The statistical test used was two sided. The lifetime measurements were carried out from two to three independent expression assays performed in N. benthamiana (leaf samples were taken between 36 and 48 hours after infiltration with A. tumefaciens).
Mean lifetime, T, in nanoseconds (ns). For each nucleus, average fluorescence decay profiles were plotted and fitted with exponential function using a non-linear square estimation procedure and the mean lifetime was calculated according to τ = Σ αiti² / Σ αiti with I(t) = Σ αi e-t/ti.
Δt=τD – τDA (in ps).
Standard error.
Standard error of the mean.
Total number of measured nuclei.
% FRET efficiency: E=1 – (τDA/τD).
p value of the difference between the donor lifetimes in the absence and in the presence of acceptor (Student’s t test).
