An Intracellular Micro-Organism Associated With Tissues of Heterodera Spp

An Intracellular Micro-Organism Associated With Tissues of Heterodera Spp AN INTRACELLULAR MICRO-ORGANISM ASSOCIATED WITH TISSUES OF HETERODERA SPP. BY AUDREY M. SHEPHERD, SYBIL A. CLARK and ANNELISE KEMPTON Rothamsted Experimental Station, Harpenden, Herts., England The ultrastructure of a bacterium-like organism found living intracellularly in tissues of two Heterodera spp., one a population of H. rostochiensis from Bolivia, S. America, and the other a population of H. goettingiana from Lincolnshire, England, is described. The organism was particu- larly abundant in the reproductive system but did not prevent the production of fertilised eggs.
