Appropriate regulation of transcription in higher plants requires specific cis elements the regulatory regions genes and their corresponding trans-acting proteins. Analysis cauliflower mosaic virus (CaMV) 35S promoter has contributed to understanding transcriptional mechanisms. The intact confers constitutive expression upon heterologous most plants. Dissection into subdomains that are able confer tissue-specific gene demonstrated a modular organization. When selected combined, they not detected from isolated subdomains, suggesting synergistic interactions occur among elements. patterns conferred by combinations differ tobacco petunia. This indicates combinatorial code cisregulatory may be interpreted differently different species.
