The MYB36 transcription factor orchestrates Casparian strip formation [PDF]
Proceedings of the National Academy of Sciences, 2015 The endodermis in roots acts as a selectivity filter for nutrient and water transport essential for growth and development. This selectivity is enabled by the formation of lignin-based Casparian strips.

Physiological roles of Casparian strips and suberin in the transport of water and solutes. [PDF]
New Phytol, 2021 Summary The formation of Casparian strips (CS) and the deposition of suberin at the endodermis of plant roots are thought to limit the apoplastic transport of water and ions. We investigated the specific role of each of these apoplastic barriers in the control of hydro‐mineral transport by roots and the consequences on shoot growth.

A peptide hormone required for Casparian strip diffusion barrier formation in Arabidopsis roots [PDF]
Science, 2017 Plants achieve mineral ion homeostasis by means of a hydrophobic barrier on endodermal cells called the Casparian strip, which restricts lateral diffusion of ions between the root vascular bundles and the soil. We identified a family of sulfated peptides

Root cell wall plasticity in iron homeostasis: an overlooked frontier in plant nutrition. [PDF]
New PhytolSummary Iron (Fe) is an essential micronutrient for plant growth and development, yet its availability in soils is often limited or excessive, leading to widespread Fe deficiency or toxicity that constrains crop productivity. While Fe uptake, transport, and signaling pathways have been well characterized, the role of the root cell wall as a dynamic ...

Plant Biology: Journey to the Center of the Casparian Strip [PDF]
Current Biology, 2020 Diffusion barriers in roots play an important role in regulating the movement of compounds between the soil environment and the vasculature. A new study provides new mechanistic insights into how a pair of copper-binding proteins facilitate the formation of a lignified nanodomain within Casparian strips.

Developmental anatomy of Cyperus laxus (non-Nranz) and Fimbristylis dichotoma (Kranz) (Cyperaceae, Poales) and tissue continuity [PDF]
Anais da Academia Brasileira de Ciências, 2013 The Cyperaceae species are present in different ecosystems and constitute the herbaceous extract. Of the approximately 5,500 species of the family; a third has Kranz anatomy, representing an important characteristic of the taxonomy and phylogeny of the ...

The microstructure of the root of Euryale ferox Salisb. (Nymphaeaceae) from the Russian Far East
Трансформация экосистем, 2023 Roots of Euryale ferox Salisb. a rare hydrophyte of the family Nymphaeaceae from the Russian Far East, are anatomically studied. These roots are characterized by a primary structure with typical proportions of histological and topographic zones. There is

eLife, 2022 Efficient uptake of nutrients in both animal and plant cells requires tissue-spanning diffusion barriers separating inner tissues from the outer lumen/soil. However, we poorly understand how such contiguous three-dimensional superstructures are formed in
