Fig. 5

Examples of differences in macroscopic morphology, cell wall organization, and aromatic abundance as shown by autofluorescence between switchgrass anatomical fractions from internode I2. Confocal laser scanning microscopy carried out using laser emission wavelengths of 405 and 543 nm. Tissue types are denoted from the following notation: Ep epidermis, Fb fiber bundles, Vb vascular bundles, Ph phloem, X xylem, Pc parenchyma cells. Scale bars represent 200 µm
