The ENOD40 gene is induced early during Rhizobium-legume symbiosis and has probably a primary role in the nodule organogenesis. In this paper we show that the 1.7 kb 5′-flanking region of the GmENOD40(2) is able to drive the expression of a gusA-int marker in transgenic Arabidopsis thaliana. The promoter activity is developmentally regulated and the major activity is detected in the root and in the stigma.
