DESCRIPTION:Land plants and beneficial arbuscular mycorrhizal (AM) fungi f
 orm life-long associations that depend on the reciprocal trade of essentia
 l soil minerals such as inorganic phosphate (Pi) in exchange for host phot
 osynthates. As obligate biotrophs\, AM fungi rely on plants for fatty acid
 s\, needed to form highly branched intracellular feeding structures called
  arbuscules and essential to complete their life-cycle. Transient invasion
  of arbuscules into root cortical cells result in greatly expanded membran
 e surfaces and provide a large symbiotic interface for symbiotic exchange.
  Although such synchronized intimacy between host and fungus must be the c
 onsequence of a precisely tuned exchange of signals\, to date\, host-signa
 ling components operating at the plant-derived peri-arbuscular membrane (P
 AM) surrounding arbuscules have not been reported. Here\, I describe a PAM
 -specific Ser/Thr receptor-like kinase that whilst not required for arbusc
 ule establishment is indispensable for completion of the fungal life-cycle
 . Our results provide a first indication that the stage post-arbuscule dev
 elopment is critical for maintaining AM symbiosis.
