A rapid staining method for the detection of suberin lamellae in the root endodermis and exodermis [PDF]
Plant BiotechnologyHistochemical detection of suberin lamellae has remarkably advanced our understanding of the roles of the apoplastic diffusion barrier in the root endodermis and the oxygen diffusion barrier in the root exodermis. Fluorol yellow 088 detects the aliphatic component of suberin and is one of the most reliable stains for detecting suberin lamellae in the ...

Groups of multi-cellular passage cells in the root exodermis of Echinochloa crus-galli varieties lack not only suberin lamellae but also lignin deposits. [PDF]
Plant Signal Behav, 2020 Passage cells are frequently found in the exodermis and the endodermis of the roots. Because passage cells lack an apoplastic diffusion barrier, they are thought to provide pathways for the transport of nutrients and the entrance of endomycorrhizal fungi. Exodermal passage cells possess Casparian strips but not suberin lamellae.

Casparian bands and suberin lamellae in exodermis of lateral roots: an important trait of roots system response to abiotic stress factors. [PDF]
Ann Bot, 2017 Root absorptive characteristics rely on the presence of apoplastic barriers. However, little is known about the establishment of these barriers within a complex root system, particularly in a major portion of them - the lateral roots. In Zea mays L., the exodermis differentiates under the influence of growth conditions.

Suberin in plants: biosynthesis, regulation, and its role in salt stress resistance [PDF]
Frontiers in Plant ScienceSoil salinization represents a significant global ecological challenge. Plants encounter salt stress in their growth environments. Suberin, a hydrophobic polymer, plays a critical role in plant salt tolerance. This review examines the mechanisms by which

Assimilation of ‘omics’ strategies to study the cuticle layer and suberin lamellae in plants [PDF]
Journal of Experimental Botany, 2017 The assembly of the lipophilic cuticle layer and suberin lamellae, approximately 450 million years ago, was a major evolutionary development that enabled plants to colonize terrestrial habitats. The cuticle layer is composed of cutin polyester and embedded cuticular waxes, whereas the suberin lamellae consist of very long chain fatty acid derivatives ...

Changing the Dimensions of Suberin Lamellae of Green Cotton Fibers with a Specific Inhibitor of the Endoplasmic Reticulum-Associated Fatty Acid Elongases [PDF]
Plant Physiology, 1996 The fibers of the green lint mutant of cotton (Gossypium hirsutum L.) contain large amounts of wax and are suberized. More than 96% of the bifunctional aliphatic suberin monomers ([alpha],[omega]-alkanedioic acids and [omega]-hydroxyalkanoic acids) have chain lengths of C22 and C24 in green cotton fiber suberin.

Phosphorus-Deficiency-Induced Development of Root Apoplastic Barriers Restricts Cadmium Translocation in Salix caprea [PDF]
PlantsPhosphorus (P) plays a crucial role in the translocation and accumulation of cadmium (Cd) in plants; however, its effects on Cd transport via the apoplastic pathway remain unclear.

Regulatory Roles of MYB Transcription Factors in Root Barrier Under Abiotic Stress [PDF]
PlantsPlant roots form highly specialized apoplastic barriers that regulate the exchange of water, ions, and solutes between the soil and vascular tissues, thereby protecting plant survival under environmental stress.
