Figure 4.8 Eudicot and monocot root systems. (A ,C & E) represent eudicot roots while (B, D & F) represent monocot roots. Schematic showing the dominant root types of tomato (A) and maize (B). SR = stem roots, P = primary root, L = lateral root, Br = brace root, Cr = crown root, S = seminal root (original diagram courtesy A. Rasmussen). MicroCT images of tomato (C) and maize (D) (images courtesy J. Johnson and S. Mairhofer). Cross section schematics of the eudicot Arabidopsis (E) and rice (F) showing where new roots initiate.
