Figure 3. XA21 Is Mainly Localized to the Endoplasmic Reticulum in Rice Leaf Sheath Tissue.

In planta subcellular localization of Nat XA21-YFP (top) and non-transgenic Kitaake (bottom) were determined using confocal microscopy. Intact adaxial sheath epidermal cells were imaged with an Olympus FV1000 confocal microscope equipped with a 60×oil immersion lens [numerical aperture, 1.42]. YFP signal was excited at 515 nm and emission was collected between 530-560 nm. Scale bar, 5 µm.
