The G-box: a ubiquitous regulatory DNA element in plants bound by the GBF family of bZIP proteins.

The G-box (CACGTG) is a ubiquitous, cis-acting DNA regulatory element found in plant genomes. Proteins known as G-box factors (GBFs) bind to G-boxes in a context-specific manner, mediating a wide variety of gene expression patterns. We suggest that, as for many biological systems, different combinations of these common elements can lead to diversity and specificity in the regulation of plant gene expression.
