Seven-day-old light-grown seedlings of wild-type and 35S:ARR7 were either mock-treated or treated with 5 mM BA for 30 min or 2 h, total RNA was isolated, and followed by the GeneChip experiments. Cytokinin-regulated A-type ARR and AHK genes that exhibit, on average, >2-fold change are presented. The expression levels (y axis) represent differential hybridizations between perfectly matched and mismatched oligodeoxyribonucleotides and average values of two independent biological experiments. Shaded and thick columns indicate wild-type and 35S:ARR7 transgenic plants, respectively
