Zea mays CPP Family


Cvitanich et al. 2000:Nodulin genes are specifically expressed in the nitrogen-fixing root nodules. We have identified a novel type of DNA-binding protein (CPP1) interacting with the promoter of the soybean leghemoglobin gene Gmlbc3. The DNA-binding domain of CPP1 contains two similar Cys-rich domains with 9 and 10 Cys, respectively. Genes encoding similar domains have been identified in Arabidopsis thaliana, Caenorhabditis elegans, the mouse, and human. The domains also have some homology to a Cys-rich region present in some polycomb proteins. The cpp1 gene is induced late in nodule development and the expression is confined to the distal part of the central infected tissue of the nodule. A constitutively expressed cpp1 gene reduces the expression of a Gmlbc3 promoter-gusA reporter construct in Vicia hirsuta roots. These data therefore suggest that CPP1 might be involved in the regulation of the leghemoglobin genes in the symbiotic root nodule.
