Secondary dilatation growth in the root endodermis

2001
Early secondary growth of roots with persisting cortex is the result of two different growth processes: Cambial growth and dilatation growth. Vascular cambium forms the secondary vascular tissues of the thickening vascular cylinder. At the same time, reactivated, peripherally situated cortex is adequately expanding by the dilatation growth.

The root endodermis in Ranunculus acris. II. Histochemistry of the endodermis and the synthesis of phenolic compounds in roots

Canadian Journal of Botany, 1979
Results of histochemical tests performed on fresh root tissue of Ranunculus acris provide the following information on the chemical nature of the root endodermis: (i) the Casparian strip is impregnated with lipid and possibly lignin, (ii) the suberin lamellae stain positively for lipid and phenols with free hydroxyl groups, and (iii) the tertiary wall

A novel protein family mediates Casparian strip formation in the endodermis

Nature, 2011
Polarized epithelia are fundamental to multicellular life. In animal epithelia, conserved junctional complexes establish membrane diffusion barriers, cellular adherence and sealing of the extracellular space. Plant cellular barriers are of independent evolutionary origin.

The mechanical role of the endodermis in Equisetum plant stems

American Journal of Botany, 2004
The endodermis of different species of the genus Equisetum has different configurations, two or one continuous layers or a sheath only around the vascular bundles. The question whether the endodermis contributes to the mechanical stability of the aerial shoots is investigated in two ways: In a direct approach, the endodermis of segments of E.

ULTRASTRUCTURAL STUDIES OF PINUS PINASTER NEEDLES: THE ENDODERMIS

American Journal of Botany, 1978
The endodermis in the needles of Pinus pinaster was examined with light and electron microscopy. The endodermis is composed of very long, radially flattened cells, filled with a large central vacuole, which contains spherical dense bodies whose concentration decreases from the ends of the cell to the middle part.

The structure of the stem endodermis in etiolated pea seedlings

Canadian Journal of Botany, 1987
Differentiation of the endodermis was examined in third internodes of etiolated Pisum sativum L. cv. Alaska seedlings. The endodermis in young internodes contains large, sedimented amyloplasts; in older internodes, a casparian strip differentiates and the endodermis becomes depleted of starch except for the proximal region of the stem, which retains ...

XXVIII.—The Stem-Endodermis in the Genus Piper

Transactions of the Royal Society of Edinburgh, 1931
The stem of the various species of Piper is characterised by its anomalous vascular structure. Medullary bundles are present throughout the genus, and there is, in addition, a modified type of secondary thickening. During an investigation of these features my attention was called by Professor Montagu Drummond to certain endodermal characters which ...

IV.—The Occurrence of Cell Division in the Endodermis

Proceedings of the Royal Society of Edinburgh, 1931
Summary1. Endodermal cells frequently show considerable increase in tangential dimension at a late stage in their existence, as a result of which the continuity of the endodermis may be maintained, despite the rapid expansion of the intra-endodermal cylinder following secondary growth.2.
