In higher organisms, gene promoters and their cis-regulatory element composition play an essential role for the regulation of gene transcription. Hence, identification and functional characterization of cis-elements has become a major task for understanding the regulatory mechanisms and circuits. In this work, various complementary approaches that make use of phylogenetic approaches and/or the combination of genome and transcriptome data have been applied to address large-scale detection of cis-regulatory elements in grass species for the first time. Moreover, evolutionary analysis of novel and verified cis-elements has been undertaken in Arabidopsis linage and among five distinct platid genomes of Oenothera species. Together, a foundation on the path was laid to develop a compendium of functional elements for plants, including their compositions, evolutionary mechanisms and functions on phenotypic changes.
