The causal organism of Stewart's disease of maize (Aplanobacter stewarti) has been found to enter the roots of plants grown in artificially infested soil through wounds inflicted artificially or by the agency of grubs. Histological and isolation studies showed that in the leaf tissue the bacteria escaped from the vessels and entered the parenchyma, causing discoloration, plasmolysis, and death of the cells.
