# s-phyto: versatile SERK1, in shedding and growing ...

<< During  their  lifeplants  constantly  renew  themselvesThey  sprout  new  leaves  in  the  spring  and shed  them  in  the  fall.  >>

<< When  it  is time  to  shed  an  organ,  a  small  hormone  binds  to  this  membrane  receptor  and,  together  with  a helper  proteinthe  abscission  process  is  initiated. >>

<< To  fully  initiate  the abscission  processanother  player  is  neededthe  helper  protein  SERK1. >>

<< The  fascinating  thing  about  SERK1  is  that  it  not  only  plays  a  role  in  the  shedding  mechanism  of plant  organsbut  also  acts  together  with  other  membrane  receptors  that  regulate  totally  different aspects  of  plant  development >>

<< IndeedSERK1  is  a versatile  helper  protein  shared  between  different  signaling  pathwaysWhen  bound  to  another protein  receptorit  can  also  for  example  signal  the  plant  to  grow. >>
