Four candidate genes exhibit altered root growth in T-DNA insertion lines.

<p>T-DNA lines for candidate genes in six of the seven epistatic regions were tested for root length differences to wild-type (<i>Col-0</i>). The gene models for the tested T-DNA insertion lines are pictured. For four of the six loci, a T-DNA line exhibited significantly different root length from <i>Col-0</i> (significantly different lines are marked with a * in the figure).
