ENOD40, an early nodulin gene, is expressed following inoculation with Rhizobium meliloti or by adding R.meliloti-produced nodulation (Nod) factors or the plant hormone cytokinin to uninoculated roots. It is detectable in the root pericycle opposite the nodule primordium even before the appearance of infection threads, and is also found later on, associated with vascular strands in mature nodules. Comparison of the enod40 sequence isolated from several legumes and one non-legume did not reveal any conserved large ORF. Instead, a conserved region was found which may allow the production of a particularly stable cytoplasmic RNA. Therefore it has been proposed that enod40 encodes an RNA with regulatory function. In addition ENOD40 also shows a very short ORF of only 10–13 amino acids, but the 34-untranslated region appears to have important functions as a riboregulator. |
