Ultrastructure of Gladiolus x hybridus root endodermis
Acta Societatis Botanicorum Poloniae, 2014 Gladiolus.x hybridus Van Houtte roots had primary, secondary and tertiary endodermis depending on the distance from the root apex. Free calcium ions were localized with the method of Slocum and Roux (1982). Electron microscopic observations revealed that

A Mechanism for Localized Lignin Deposition in the Endodermis [PDF]
Cell, 2013 The precise localization of extracellular matrix and cell wall components is of critical importance for multicellular organisms. Lignin is a major cell wall modification that often forms intricate subcellular patterns that are central to cellular function. Yet the mechanisms of lignin polymerization and the subcellular precision of its formation remain

SUBERMAN regulates developmental suberization of the Arabidopsis root endodermis [PDF]
Plant Journal, 2020 SummaryRoot endodermis, the innermost cortical layer surrounding the root vasculature, serves as the foremost barrier to water, solutes, and nutrients taken up from soil. Endodermis barrier functionality is achieved via its hydrophobic coating of lignified Casparian strips and the suberin lamellae; nonetheless the regulatory mechanisms underlying ...

Coordination between microbiota and root endodermis supports plant mineral nutrient homeostasis [PDF]
Science, 2021 Microbes modify plant root permeability The root provides mineral nutrients and water to the plant. Diffusion barriers seal the root, preventing the loss of internal water and nutrients. Salas-González et al. found that microbes living on and in roots of the model plant

Discrete and cell-specific hypoxic responses in Arabidopsis roots resolved by single-nuclei transcriptomics. [PDF]
New PhytolSummary With the intensification of unpredictable flooding events because of global warming, there is a need to understand how root cells perceive and respond to oxygen deprivation. The use of high‐throughput single‐nuclei RNA‐sequencing (snRNA‐Seq) allows the examination of gene expression profiles in discrete cell types.

Unique lignin modifications pattern the nucleation of silica in sorghum endodermis [PDF]
Journal of Experimental Botany, 2020 Abstract Silicon dioxide in the form of hydrated silica is a component of plant tissues that can constitute several percent by dry weight in certain taxa. Nonetheless, the mechanism of plant silica formation is mostly unknown. Silicon (Si) is taken up from the soil by roots in the form of monosilicic acid molecules.

PIF1 Regulates Plastid Development by Repressing Photosynthetic Genes in the Endodermis [PDF]
Molecular Plant, 2016 Mutations in Phytochrome Interacting Factors (PIFs) induce a conversion of the endodermal amyloplasts necessary for gravity sensing to plastids with developed thylakoids accompanied by abnormal activation of photosynthetic genes in the dark. In this study, we investigated how PIFs regulate endodermal plastid development by performing comparative ...
