Abstract: The infection threads in root nodules of Elaeagnus confera appear in the intercellular spaces at muItiple cell junctions.No root hairs are observed to be deformed in which nodules appear.The infection threads are scrotiform,containing filamentous materials and stromata;their walls thicken partly or completely and are linked together with host cell walls,Infection threads are varied morphologically.In infected cells of E.confera,cell nuclei swell and produce a few branches and form fingered nuclei.The endo-phytes and organelle in infected cells disappear with the senescene of infected cells.
