Two photon fluorescence (TPF) and second harmonic generation (SHG) images of fresh intact wild-type Columbia-0 (Col-0) leaf and fresh intact starch excess 1 (sex1) mutant leaf. The last column shows the combined TPF and SHG images. The TPF images were acquired with a 670/30Â nm filter, while SHG images were acquired with a 532/3Â nm filter. The pixel dwell time was 0.016Â ms and 0.128Â ms for the TPF and SHG image acquisitions, respectively.
