Pattern of <i>VQ29</i> expression in <i>Arabidopsis thaliana</i> roots infected with <i>Phytophthora parasitica</i>.

<p>Confocal image of N60000 expressing the <i>ProVQ29</i>:<i>GFP</i> transgene. Two independent lines (#1 and #5) were analyzed and gave similar results. Only the results for <i>ProVQ29</i>:<i>GFP</i> #1 are presented here. (GFP) <i>ProVQ29</i>:<i>GFP</i> expression, (DIC) differential interference contrast, and (MERGE) merged images are shown. Roots were infected with 1x10⁶ zoospores of <i>P</i>. <i>parasitica</i> and GFP expression was followed for 30 hours after infection. No GFP was detected in non-infected roots. Bars, 20 μm. Arrows indicate appressoria, and stars indicate penetration points.
