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. [1] There is some evidence that the non-coding characteristics of this gene are more widely conserved than the protein coding sequences. [2] In soyabeans enod40 was found to be expressed during early stages of formation of nitrogen-fixing root nodules that are associated with symbiotic soil rhizobial bacteria. [3] [4] The gene is also active in roots containing fungi forming phosphate-acquiring arbuscular mycorrhiza. [5] 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. [6] In the study of non-legume plants, the over-expression of ENOD40 in transgenic Arabidopsis lines was observed a reduction of cell expansion. [7]
