Fluorescence decay kinetics of hydrated and desiccated Rhytidium rugosum at room temperature. (A, B) Wavelength-decay time 2D image of fluorescence of desiccated (A) and rehydrated (B) thalli. (C) Fluorescence spectra calculated by integrating photons in whole time domains of the images in A (red, desiccated) and B (blue, rehydrated) with the A spectrum normalized to the highest peak of the B spectrum (red dotted trace). (D) Semi-logarithmic plots of fluorescence decay time courses at 670, 690, 720, and 750 nm, calculated from the images of desiccated (red) and hydrated (blue) thalli.
