The MYB36 transcription factor orchestrates Casparian strip formation. [PDF]
Proc Natl Acad Sci U S A, 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.

The Arabidopsis SGN3/GSO1 receptor kinase integrates soil nitrogen status into shoot development [PDF]
The EMBO JournalThe Casparian strip is a barrier in the endodermal cell walls of plants that allows the selective uptake of nutrients and water. In the model plant Arabidopsis thaliana, its development and establishment are under the control of a receptor-ligand ...

A Genome-Wide Identification and Expression Analysis of the Casparian Strip Membrane Domain Protein-like Gene Family in Pogostemon cablin in Response to p-HBA-Induced Continuous Cropping Obstacles [PDF]
Plants, 2023 Casparian strip membrane domain protein-like (CASPL) genes are key genes for the formation and regulation of the Casparian strip and play an important role in plant abiotic stress. However, little research has focused on the members, characteristics, and

Rice OsCASP1 orchestrates Casparian strip formation and suberin deposition in small lateral roots to maintain nutrient homeostasis [PDF]
Frontiers in Plant Science, 2022 Arabidopsis Casparian strip membrane domain proteins (CASPs) form a transmembrane scaffold to recruit lignin biosynthetic enzymes for Casparian strip (CS) formation.

A dirigent family protein confers variation of Casparian strip thickness and salt tolerance in maize [PDF]
Nature Communications, 2022 Most crops are farmed under high transpiring environments, but our understanding of transpiration-dependent salt tolerance (TDST) remains limited. Here, the authors report a dirigent family protein is responsible for TDST by affecting lignin deposition ...

Casparian strip membrane domain proteins in Gossypium arboreum: genome-wide identification and negative regulation of lateral root growth [PDF]
BMC Genomics, 2020 Background Root systems are critical for plant growth and development. The Casparian strip in root systems is involved in stress resistance and maintaining homeostasis. Casparian strip membrane domain proteins (CASPs) are responsible for the formation of

Spatial Expression and Functional Analysis of Casparian Strip Regulatory Genes in Endodermis Reveals the Conserved Mechanism in Tomato [PDF]
Frontiers in Plant Science, 2018 Casparian strip (CS) is an impregnation of endodermal cell wall, forming an apoplastic diffusion barrier which forces the symplastic and selective transport of nutrients across endodermis.

A receptor-like kinase mutant with absent endodermal diffusion barrier displays selective nutrient homeostasis defects [PDF]
eLife, 2014 The endodermis represents the main barrier to extracellular diffusion in plant roots, and it is central to current models of plant nutrient uptake. Despite this, little is known about the genes setting up this endodermal barrier. In this study, we report

Tetraploidy enhances boron-excess tolerance in Carrizo Citrange (Citrus sinensis L. Osb. x Poncirus trifoliata L. Raf.) [PDF]
Frontiers in Plant Science, 2016 Tetraploidy modifies root anatomy which may lead to differentiated capacity to uptake and transport mineral elements. This work provides insights into physiological and molecular characters involved in boron (B) toxicity responses in diploid (2x) and ...

Casparian strips prevent apoplastic diffusion of boric acid into root steles for excess B tolerance [PDF]
Frontiers in Plant Science, 2023 Casparian strips are ring-like structures consisting of lignin, sealing the apoplastic space between endodermal cells. They are thought to have important functions in controlling radial transport of nutrients and toxic elements in roots.
