Since its publication, the authors of Watt et al. (2008) have brought to our attention an error in their article, where some of the scale bars have been incorrectly printed in the legend to Fig. 3. The bars in panels (e–i) represent 50 µm and not 10 µm. The correct Fig. 3 is printed below.

Figure 3.

Representative cross-sections of component roots of the root systems of wheat (Triticum aestivum), barley (Hordeum vulgare) and triticale (Triticale hexaploide), grown in a controlled environment in a sandy potting soil, stained with rhodamine B and viewed with UV fluorescence optics. The anatomy of each component root did not vary among cereals (Table 3); here all images except (c) are from wheat cv. Janz; (c) is from barley cv. Beecher. (a) Primary axile root, bar, 100 µm ; (b) scutellar node axile root, bar, 100 µm; (c) coleoptile node axile root, bar, 100 µm; (d) leaf node axile root, bar, 100 µm; (e) Br5, branch root with six xylem tracheary elements (XTE), bar, 50 µm. (f) Br4, branch root with five XTE, bar, 50 µm; (g) Br3, branch root with four XTE, bar, 50 µm; (h) Br2, branch root with three XTE, bar, 50 µm; (i) Br1, branch root with two XTE, bar, 50 µm; Arrowheads, central or inner XTE; arrows, peripheral XTE; double arrowhead, root hair; c, cortex. See Fig. 1 for diagrams of the origins of roots.

We apologize to our readers for this mistake.
