Conservation of noncoding microsatellites in plants: implication for gene regulation.

ABSTRACT:

Background

Microsatellites are extremely common in plant genomes, and in particular, they are significantly enriched in the 5' noncoding regions. Although some 5' noncoding microsatellites involved in gene regulation have been described, the general properties of microsatellites as regulatory elements are still unknown. To address the question of microsatellites associated with regulatory elements, we have analyzed the conserved noncoding microsatellite sequences (CNMSs) in the 5' noncoding regions by inter- and intragenomic phylogenetic footprinting in the Arabidopsis and Brassica genomes.

Results

We identified 247 Arabidopsis-Brassica orthologous and 122 Arabidopsis paralogous CNMSs, representing 491 CT/GA and CTT/GAA repeats, which accounted for 10.6% of these types locat
