The IBR5 phosphatase promotes Arabidopsis auxin responses through a novel mechanism distinct from TIR1-mediated repressor degradation-3

R patterning defects. Cleared cotyledons of 8-day-old Col-0 (Wt), , , and seedlings are shown. Scale bar = 1 mm. (C, D) auxin-response defects. Lengths of primary roots of 8-day-old seedlings grown under yellow-filtered light at 22°C on medium supplemented with various concentrations of IBA (C) or 2,4-D (D) are shown. roots were significantly longer than and roots in the absence of hormone and on 5, 10, and 20 μM IBA (≤ 0.001) in two-tailed -tests assuming unequal variance. roots were significantly longer than and roots on 20 (≤ 0.01), 40 (≤ 0.01), 80 (≤ 0.0001), and 120 (≤ 0.001) nM 2,4-D in two-tailed -tests assuming unequal variance. Error bars represent standard errors of the means (≥ 16).<p><b>Copyright information:</b></p><p>Taken from "The IBR5 phosphatase promotes Arabidopsis auxin responses through a novel mechanism distinct from TIR1-mediated repressor degradation"</p><p>http://www.biomedcentral.com/1471-2229/8/41</p><p>BMC Plant Biology 2008;8():41-41.</p><p>Published online 18 Apr 2008</p><p>PMCID:PMC2374786.</p><p>
