Abstract
The Rhizobium lipochitooligosaccharide Nod factors are external mitogen signals that trigger nodule organogenesis in the leguminous host plant root. Nodule organogenesis is restricted to the emerging root hair zone where cortical cells opposite to the protoxylem poles can gain transient competence for cell division. This positional information is likely determined by gradients of endogenous plant morphogens. In addition, active photosynthesis and limitation of combined nitrogen are the prerequisites of nodule primordium formation.
