Figure 2From: Phylogenetic and comparative gene expression analysis of barley (Hordeum vulgare) WRKY transcription factor family reveals putatively retained functions between monocots and dicotsUnrooted phylogenetic tree of identified barley WRKY proteins. The tree was calculated on the basis of WRKY domain sequences of the barley (HvWRKY) and selected Arabidopsis (AtWRKY) and rice (OsWRKY) protein sequences as representatives for the different groups. WRKY groups and subgoups 1 to 3 are highlighted in different colors. Color coded grouping of HvWRKY36, HvWRKY6 and OsWRKY82 is based on analysis with sequences extending over the WRKY domain consensus.Back to article page
