<i>Arabidopsis wrky</i> mutants develop smaller crown galls.

<p>(A) Crown gall weights of <i>wrky18, wrky40, wrky60</i> mutants and the wild type Col-0 25 days after inoculation of <i>Arabidopsis</i> inflorescence stems with the tumorigenic <i>A. tumefaciens</i> strain C58. Bars show mean values of crown gall weight (±SE) separated from the stems of at least 40 plants from each genotype. (B) Representative pictures of the stems of the different genotypes 25 days after inoculation of <i>A. tumefaciens</i>. (C) Relative transcript numbers of the <i>Ipt</i> oncogene in stems of the wild-type plant Col-0 and the <i>wrky18/40/60</i> triple mutant 6 days post inoculation (6 dpi) of <i>A. tumefaciens</i> strain C58. Relative transcript numbers were quantified by qRT-PCR and normalized to 10,000 molecules of <i>ACTIN2/8</i>. Bars show mean values (±SD) of three independent samples. * <i>P<0.05;</i> ** <i>P<0.01</i>; *** <i>P<0.001</i> (Student’s <i>t</i>-test).
