The return of the isophasic filaments – the early Arceuthobium endophyte..

The isophasic (systemic) behaviour of some Arceuthobium species involves a synchronized growth pattern which has a relatively unknown endophyte component. We report the distribution of such an endophyte of A. douglasii as present in the undifferentiated part of the apical bud of Douglas fir (Pseudotsuga menziesii). A method was developed to create a map of the parasite within infected apical buds. Semi-thin serial sections of infected buds were stained and photographed. The micrographs were analyzed, the endophyte identified, and a simple animation created. This animation revealed a highly organized relationship between parasite and host, an important step in understanding this complex association.
