Still, root and needle transcriptional responses contrasted, with extensive root-specific downregulation of growth. Comparison between previously characterized A. thaliana drought-response genes and P. abies revealed both conservation and divergence of transcriptional response to drought. In P. abies, transcription factors belonging to the bZIP AREB/ABF (ABA Response Element Binding/ABRE Binding Factors) ABA-dependent pathway had a more limited role. These results highlight the importance of profiling both above- and below-ground tissues and provide a compr
