Scholarcy highlights

  • Root nodules are formed as a result of an orchestrated exchange of chemical signals between symbiotic nitrogen fixing bacteria and certain plants
  • In plants that form nodules in symbiosis with actinorhizal bacteria, nodules are derived from lateral roots
  • Nodules are formed de novo from pericycle and cortical cells that are re-stimulated for division and differentiation by rhizobia
  • Auxin is an important regulator of cell division and differentiation, and changes in auxin accumulation and transport are essential for lateral root development
  • Whereas auxin requirements appear to be similar for lateral root and nodule primordium activation and organ differentiation, the major difference between the two developmental programs lies in the specification of founder cells
  • We acknowledge their continuing connection to their culture, their contribution to our shared knowledge, and pay our respects to their Elders past and present
