Patterns and evolution of ACGT repeat cis-element landscape across four plant genomes.

ABSTRACT:

Background

Transcription factor binding is regulated by several interactions, primarily involving cis-element binding. These binding sites maintain specificity by means of their sequence, and other additional factors such as inter-motif distance and spacer specificity. The ACGT core sequence has been established as a functionally important cis-element which frequently regulates gene expression in synergy with other cis-elements. In this study, we used two monocotyledonous - Oryza sativa and Sorghum bicolor, and two dicotyledonous species - Arabidopsis thaliana and Glycine max to analyze the conservation of co-occurring ACGT core elements in plant promoters with respect to spacer distance between them. Using data generated from Arabidopsis thaliana and Oryza sativa, we also identifi
