Autoregulation of Legume Nodulation by Sophisticated Transcriptional Regulatory Networks

One of the remarkable features of plants is that of long-distance signaling between their root and shoot systems.This enables plants,which are sessile organisms,to respond and adapt to environmental changes such as nutrient stress(Okamoto et al.2016).Most species of legumes possess root nodules that are induced by symbiotic nitrogen-fixing rhizobia.
