Expression properties of DBD families. Expression categories (PO: patterned only, P-U: patterned-and-ubiquitous, UO: ubiquitous only, MO: maternally deposited only, NE: not-expressed; see Figure 1 legend for descriptions) for 22 DBD families with more than five members each, ordered by fraction of TFs classified as PO. For the purposes of this analysis, bZIP, bZIP_1, and bZIP_2 are grouped as a single DBD family. The number of TFs in each DBD family is indicated in parentheses after the DBD name. For reference, an additional column (All TFs) shows the distribution of all 708 TFs by expression category. See Additional file 1: Table S1 for more information about DBD names, with Pfam and InterPro identifiers.
