Representative images of root sections from Spirodela polyrhiza and Lemna gibba alongside the main root of Pistia stratiotes. Images were obtained via fresh tissue sectioning and confocal imaging following staining with calcofluor (cellulose/cyan) and basic fuchsin (lignin/magenta). Scale bars for Pistia stratiotes, 500 μm (top left) and 100 μm (top right). Scale bars for Spirodela polyrhiza and Lemna gibba, 50 μm (bottom left) and 10 μm (bottom right). x, central xylem; p, phloem parenchyma; En, endodermis; Ep, epidermis; consecutive cortex cell layers are shown with asterisks. See also Figure S1 for additional species.
