Emission spectra of autofluorescent molecules: fluorescence emission spectra of various components of Arabidopsis tissues, taken with two-photon excitation at 790 nM. Potential overlap with fluorophores is possible in the blue–green and red region of the visible spectra. Note that this spectra is very specific to the respective plant and tissue material.
