The gene ENOD40 is expressed during early stages of legume nodule development. A homolog was isolated from tobacco, which, as does ENOD40 from legumes, encodes an oligopeptide of about 10 amino acids. In tobacco protoplasts, these peptides change the response to auxin at concentrations as low as 10(-12) to 10(-16)M. The peptides encoded by ENOD40 appear to act as plant growth regulators.
ENOD40基因在豆科植物根瘤发育的早期阶段表达。从烟草中分离出了一个同源物，它与豆科植物的ENOD40一样，编码一种约10个氨基酸的寡肽。在烟草原生质体中，这些肽在低至10^(-12)至10^(-16)M的浓度下就能改变对生长素的反应。ENOD40编码的肽似乎起着植物生长调节剂的作用。
