enod40, also known as early nodulin 40, is a gene found in flowering plants. The gene has characteristics of both protein and Non-coding RNA genes. There issome evidence that the non-coding characteristics of this gene are more widely conserved than theprotein coding sequences.In soyabeans enod40 was found to be expressed duringearly stages of formation of nitrogen-fixing root nodules that are associated with symbiotic soil rhizobial bacteria.The gene is also active in roots containing fungi forming phosphate-acquiring arbuscular mycorrhiza.An interaction with a novel RNA-binding protein MtRBP1 (Medicago truncatula RNA-binding protein 1) investigated in the development of Root nodule suggests ENOD40 has a function of cytoplasmic relocalization of nuclear proteins.In the study of non-legume plants, the over-expression of ENOD40 in transgenic Arabidopsis lines was observed a reduction of cell expansion. enod40, also known as early nodulin 40, is a gene found in flowering plants.
