It seems to be associated with lignification of host endodermis and pericycle cells at the penetration site. |
There were no visible differences in the development of endodermis between the two varieties and growth conditions. |
The chemical composition of cell walls from endodermis and hypodermis was analysed. |
The pericycle and endodermis were both present, each as a single sheath of cells located between the cortex and stele. |
In addition, the host pericycle and endodermis in contact with abortive haustoria were deformed in many cases. |
The length of the largest starch grains was measured from three cells of the endodermis per cross-section with a micrometer ocular. |
