Regulatory networks of salt stress and abscisic acid (ABA) responses have previously been analyzed in seed plants. We report microarray expression profiles of transcription-associated proteins (TAPs) in response to salt stress and ABA in the salt-tolerant moss Physcomitrella patens. We find that the role of DREB-like, Dof, and bHLH TAPs in salt stress responses have been conserved during embryophyte evolution, and that the function of ABI3-like, bZIP, HAP3, and CO-like TAPs in seed development and flowering emerged from pre-existing pathways.
