Figure 3From: Identification of lignin genes and regulatory sequences involved in secondary cell wall formation in Acacia auriculiformis and Acacia mangium via de novo transcriptome sequencingTranscription factors involved in regulation of wood formation and lignin biosynthesis. (A) Number of contigs found in A. auriculiformis and A. mangium corresponding to five major wood-related transcription factor families (E-value ≤ 1E-10); (B) Phylogenetic tree of R2R3-MYBs of A. auriculiformis, A. mangium and other plant species that are involved in secondary cell wall formation. The neighbour-joining tree was obtained with MEGA 5.0 software and ClustalW2 alignments of full length amino acid sequences. Bootstrap values > 50% are shown. The bar indicates an evolutionary distance of 0.1.
