Regulation of npcRNAs under conditions modifying root architecture. Expression of npcRNAs in roots of plants grown in low (−P) or high (+P) phosphate conditions and in the presence of cytokinin (BA) was examined. Real-time RT-PCR was performed for npcRNAs 34, 43, and 60 and data were normalized with ACTIN2. Values for roots grown in high-phosphate conditions or not treated with 0.1 μm BA are arbitrarily fixed to 1. For each cDNA synthesis, quantifications were made in triplicate and two biological replicates (I and II) were analyzed. Values are means ± sds.
