Root hair phenotypes of the WT, <i>ein3</i>, <i>ein3eil1</i>, and <i>EIN3 OX</i> lines.

<p>(A), Root hair patterns of the first 3 mm of the root tips of 7-day-old WT, <i>ein3</i>, <i>ein3eil1</i>, and <i>EIN3 OX</i> seedlings grown on P+ and P- media. (B) and (C), Quantitative analyses of root hair density and length of the WT, <i>ein3</i>, <i>ein3eil1</i>, and <i>EIN3 OX</i> seedlings in (A). Values represent means ± SD of three replicates. Asterisks indicate a significant difference from the WT (<i>t</i>-test, P < 0.05).
