Extended Data Fig. 6. FRET ratio of AuxSen quantified in protoplasts.

Extended Data Fig. 6

Cell-suspension-culture protoplasts were transfected with pJIT60-2xp35SS:NLS:AuxSen and the FRET response was captured by flow cytometry as the ratio of the emission between the Aquamarine peak intensity (FL9) and mNeonGreen peak intensity (FL10) as ‘Log_Height’ (a.u.). a, Normalized excitation and emission spectra for mNeonGreen and Aquamarine. The 405-nm laser line is shown as a vertical bar and bandpass filters are shown as open boxes, as rendered by FPBase44. As FRET occurs, the emission output is shifted from the FL9 to the FL10 bandpass. b, Baseline level of AuxSen FRET response, without exogenous IAA. c, Maximal response level of AuxSen with 10 mM IAA.
