ACGT containing promoters and their regulation under specific conditions. (A) Using microarray based expression data in Arabidopsis, an analysis of 26 different conditions revealed a potential regulation of ACGT (N) ACGT containing promoters by environment conditions of salt and drought, and jasmonic acid. (B) Dot plots of ACGT and control elements in Arabidopsis for each of the conditions show high likelihood values for ACGT, which are significant for up-regulation by salt and drought stress. (C) Dot plots of ACGT and control elements for up regulation by salt and drought stress in Rice show high likelihood values for ACGT similar to those seen for Arabidopsis. * p < 0.5.
