It seems to be associated with lignification of host endodermis and pericycle cells at the penetration site. |
|
In the classical view, the former component becomes zero at the endodermis. |
|
In the endodermis and exodermis of roots, the apoplastic flow component can be modified by the existence of apoplastic barriers. |
|
The root endodermis and, to a lesser extent, exodermis have been identified as possible membrane control points for radial water flux in roots. |
|
There were no visible differences in the development of endodermis, exodermis and aerenchyma between the two varieties and growth conditions. |
|
The chemical composition of cell walls from endodermis and hypodermis was analysed. |
|
The endodermis surrounding the vascular cylinder of the corm effectively blocked outward diffusion of the solutes. |
|
There were no visible differences in the development of endodermis between the two varieties and growth conditions. |
|
The length of the largest starch grains was measured from three cells of the endodermis per cross-section with a micrometer ocular. |
|
In addition, the host pericycle and endodermis in contact with abortive haustoria were deformed in many cases. |
|
The pericycle and endodermis were both present, each as a single sheath of cells located between the cortex and stele. |
|
Consequently, ions are taken up into the symplasm at the plasma membranes of the epidermis or cortex or the outer face of the endodermis. |
|
The endodermis of the root is well marked, and Casparian strips are present, as in the stem. |
|
It was shown to be localized to root endodermis and flowers. |
|
It in turn is bounded by a pericycle of one or two cell layers and a single cell layer of endodermis. |
|
Called the incipient apex, the dome pushes out the surrounding endodermis, which may itself resume divisions, its daughter cells enlarging to create a sheath around the new root tip. |
|
As a rule, angiosperm stems have no endodermis or definable pericycle. |
|
The endodermis with its casparian strips may function in regulating the flow of water between outer tissues and the vascular cylinder at the centre of the root. |
