摘要：

In Zea mays, two ENOD40 homologous were identified that show only 30% of sequence homology to each other. We identified line e40-mum1 carrying a Mu transposon inserted in ZmENOD40-1, the maize gene that has the highest homology to leguminous ENOD40. The insertion causes a dramatic reduction of the ZmENOD40-1 transcript level. Irrespective of this, homozygous e40-mum1 plants are still able to interact with mycorrhizal fungi. Furthermore, no phenotypic aberrations correlated to the presence of e40-mum1 have been identified and therefore it is suggested that Z mays ENOD40 genes are functionally redundant despite their strikingly low homology.
