Casparian strips prevent apoplastic diffusion of boric acid into root steles for excess B tolerance
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.

Two chemically distinct root lignin barriers control solute and water balance
Nature Communications, 2021 Defects in the Casparian strip, a fine band of lignin that seals root endodermal cells and plays roles in nutrient homeostasis, activate a signaling pathway leading to over-lignification.

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

Casparian strip development and its potential function in salt tolerance. [PDF]
Plant Signal Behav, 2011 The root system is particularly affected by unfavourable conditions because it is in direct contact with the soil environment. Casparian strips, a specialised structure deposited in anticlinal walls, are characterised by the impregnation of the primary wall pores with lignin and suberin. The Casparian strips in the endo- and exodermis of vascular plant

Dual roles of suberin deposition at the endodermal Casparian strip in manganese uptake of rice. [PDF]
J Exp BotAbstract Rice roots are characterized by having two Casparian strips (CSs) at the exodermis and endodermis, where transporters for mineral nutrients are expressed. However, the exact role of the CS in expression of the transporters and subsequent nutrient uptake is poorly understood.

Frontiers in Plant Science, 2022 Drought is the most serious adversity faced by agriculture and animal husbandry industries. One strategy that plants use to adapt to water deficits is modifying the root growth and architecture.

Single-cell transcriptome sequencing atlas of cassava tuberous root
Frontiers in Plant Science, 2023 IntroductionSingle-cell transcriptome sequencing (ScRNA-seq) has emerged as an effective method for examining cell differentiation and development. In non-model plants, it hasn't been employed very much, especially in sink organs that are abundant in ...

Frontiers in Plant Science, 2017 In this paper, we present a detailed and comprehensive mathematical model of active and passive ion and water transport in plant roots. Two key features are the explicit consideration of the separate, but interconnected, apoplastic, and symplastic ...

Functional and Evolutionary Analysis of the CASPARIAN STRIP MEMBRANE DOMAIN PROTEIN Family [PDF]
Plant Physiology, 2014 AbstractCASPARIAN STRIP MEMBRANE DOMAIN PROTEINS (CASPs) are four-membrane-span proteins that mediate the deposition of Casparian strips in the endodermis by recruiting the lignin polymerization machinery. CASPs show high stability in their membrane domain, which presents all the hallmarks of a membrane scaffold. Here, we characterized the large family

Plant epithelia: What is the role of the mortar in the wall?
PLoS Biology, 2018 In a growing plant root, the inner vascular system is sealed off by an epithelium, the endodermis. The space between all of the cells in the endodermal layer is filled with an impermeable mass called the Casparian strip, which closes the spaces between ...
