The endodermis and shoot gravitropism
Trends in Plant Science, 1999Shoots and roots of higher plants exhibit negative and positive gravitropism, respectively. A variety of gravitropic mutants have recently been isolated from Arabidopsis, the characterization of which demonstrates that the molecular mechanisms of the gravitropic responses in roots, hypocotyls and inflorescence stems are different.

A novel protein family mediates Casparian strip formation in the endodermis
Nature, 2011Polarized 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.

Bacterial community and root endodermis: a complementary relationship
Trends in Plant Science, 2023There are feedforward and feedback loops along the microbiota-root-shoot axis to maintain plant growth or defense under environmental stresses. Here, we highlight a reciprocal interaction between the endodermis and the plant-bacterial community, which stabilizes the diffusion barriers to maintain nutrient homeostasis under nutritional stress.

Ultrastructure and development of apoplastic barriers within indeterminate root nodules formed by Vicia faba L. were examined by light and electron microscopy. The nodule outer cortex is separated from the inner cortex by a heavily suberized nodule endodermis, which matures in submeristematic regions and possesses suberin lamellae.

The endodermis, a tightly controlled barrier for nutrients
Current Opinion in Plant Biology, 2017Plant roots acquire nutrients from the soil and transport them upwards to the aerial parts. To reach the central vasculature of the root, water and nutrients radially cross all external cell layers. The endodermis surrounds the vascular tissues and forms diffusion barriers.

The endodermis as a checkpoint for nutrients
New Phytologist, 2016SummaryPlant roots forage the soil for nutrients and transport them upwards to the aerial parts. Nutrients entering the plant are transported through the concentric layers of epidermis, cortex and endodermis before reaching the central vasculature. The endodermis is the innermost cortical cell layer that surrounds the vasculature.

Secondary dilatation growth in the root endodermis
2001Early 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.

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

The mechanical role of the endodermis in Equisetum plant stems
American Journal of Botany, 2004The 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.
