Developmental Microarray Expression Data (AtGenExpress) of plant developmental tissues, combined with CEG coexpression analysis regulatory (7mer) motif calculations (ATTED-II). We took the median of triplicate measurements from AtGenExpress, then sorted the developmental series into plant tissues, with one category for seedlings (8 days old or less) and another for whole plants (older than 8 days).
