Transcription profiling by array of different organism parts of Arabidopsis mutant for arf7 and arf19

Arabidopsis seedlings, of both wild-type and an ARF7/ARF19 double knockout mutant, were grown to 7 days post-germination. The roots were then dissected into 5 developmental zones, the meristem, early elongation zone, late elongation zone, mature root and lateral root zone. The sections then underwent transcriptional profiling to identify processes and regulatory events specific and in common to the zones.
