Structural motifs in the RNA encoded by the early nodulation gene enod40 of soybean.

ABSTRACT: The plant gene enod40 is highly conserved among legumes and also present in various non-legume species. It is presumed to play a central regulatory role in the Rhizobium-legume interaction, being expressed well before the initiation of cortical cell divisions resulting in nodule formation. Two small peptides encoded by enod40 mRNA as well as its secondary structure have been shown to be key elements in the signalling processes underlying nodule organogenesis. Here results concerning the secondary structure of mRNA of enod40 in soybean are presented. This study combined a theoretical approach, involving structure prediction and comparison, as well as structure probing. Our study indicates five conserved domains in enod40 mRNA among numerous leguminous species. Structure comparison suggests
