Expression patterns and promoter analyses of aluminum-responsive NAC genes suggest a possible growth regulation of rice mediated by aluminum, hormones and NAC transcription factors

Analysis of putative motifs found in the promoter regions of Al-responsive NAC genes in our in vivo studies.
The sequences were separated according to the differential expression of the genes, where Group I encompasses genes that were expressed exclusively in the roots,; Group II includes genes that were expressed exclusively in the shoots; and Group III comprises genes that were expressed in both tissues. The motifs, 1 to 3, of each group were identified with regard to their function (Table on the top-right corner of the figure) and distribution. The promoter analysis was done using the MEME v4.11.2 software (http://meme-suite.org/tools/dreme) [55]; the distribution in the sequences with the MAST v4.11.2 software (http://meme-suite.org/tools/mast) [56], while the identification of functions was done with the Tomtom v4.11.2 software (http://meme-suite.org/tools/tomtom) [57].
