(a) Visualization of NO in primary roots. Seedlings were treated with CO at 0, 10, and 50 μM for 24 h. After treatments, the seedling roots were loaded with 15 μM 4,5-diaminofluorescence (DAF-2DA) for 15 min and immediately photographed (bar = 5 mm). (b) Visualization of NO in lateral roots. Seedlings were treated with 0 and 10 μM CO for 12, 24, 36, 48, and 60 h and then exposed to DAF-2DA for 15 min. After that, they were immediately photographed (bar = 10 mm).<p><b>Copyright information:</b></p><p>Taken from "Regulation of tomato lateral root development by carbon monoxide and involvement in auxin and nitric oxide"</p><p></p><p>Journal of Experimental Botany 2008;59(12):3443-3452.</p><p>Published online 24 Jul 2008</p><p>PMCID:PMC2529230.</p><p></p
