DESCRIPTION:Prof Bisseling and his group have been at the cutting edge of 
 research into the Rhizobium symbiosis for 2 decades\, producing many high-
 impact papers. Abstract Legumes have the unique ability to establish a sym
 biosis with Rhizobium bacteria. This interaction results in the formation 
 of root nodules. There the bacteria are hosted like transient organelles a
 nd they are able to reduce atmospheric nitrogen into ammonia.\n\nNodule fo
 rmation is set in motion by so-called Nod factors which are specific lipoc
 hito-oligosaccharides secreted by the bacteria. About 10 legume genes have
  been identified that are essential for Nod factor signaling. Among these 
 are 2 Nod factor receptors. In Medicago\, one of these functions as signal
 ing receptor involved in initiating early responses whereas the second is 
 involved in root hair curling and start of infection process. The evolutio
 n of legume Nod factor signaling genes will be discussed. \n\nhttp://www.m
