NC, number of transcription factors (TFs) conserved in rice and Arabidopsis pollen; NWG, number of diverse TFs transcripts in whole genome; NGC, number of diverse TFs transcripts in the Genechip. "-", indicating undetectable expression of the corresponding genes in Arabidopsis or rice pollen. Data for Arabidopsis pollen-expressed TFs gens were from Honys and Twell (2004). For details, see Additional file 9.
