Extended Data Fig. 4: Tissue-specific expression of AtCXE15 and subcellular localization of AtCXE15.

a-e, GUS staining assayed seedling or organs of transgenic Arabidopsis plants carrying a pAtCXE15:GUS construct. Young seedling (a–c); primary root (b); elongated lateral root (c); flower (d); mature plants (e). f, Subcellular localization of AtCXE15. Images are confocal micrographs of lateral root, lateral root meristem, and lateral root epidermal cells (from left to right) in the transgenic Arabidopsis seedlings carrying a pAtCXE15:AtCXE15:GFP construct. The fluorescence from GFP is shown in green and from FM4-64 in red. Three independent transgenic lines were characterized for each genotype and representative seedlings were photographed. The experiments were repeated at least two times independently with similar results.
