DESCRIPTION:Plants associate with microorganisms in the rhizosphere\, with
  potential for benefit or detriment. Perception of micro-organisms involve
 s recognition of chitooligosaccharides (COs) from fungal cell walls or pep
 tidoglycan (PGN) from bacterial envelopes to induce an immunogenic respons
 e.  However\, recognition of microbial surfaces does not discriminate a pa
 thogen from a symbiont and consistently we show that COs and PGN can also 
 activate symbiosis signaling in roots of Medicago truncatula and such CO p
 erception promotes colonisation by symbiotic fungi. The nutrient status of
  the plant dictates the degree to which a symbiotic or immunity response i
 s activated: nutrient starved plants preference symbiosis\; nutrient reple
 te plants immunity. Our work reveals how plants adapts their reaction to t
 he microbial community\, being welcoming or restrictive according to their
  need for microbial nutrient services. \n
