R. Mirabella et al., The soybean ENOD40(2) promoter is active in Arabidopsis thaliana and is temporally and spatially regulated, PLANT MOL B, 39(1), 1999, pp. 177-181
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 pro
moter activity is developmentally regulated and the major activity is detec
ted in the root and in the stigma.
