The MYB36 transcription factor orchestrates Casparian strip formation.
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. Casparian strip formation is initiated by the localization of the Casparian strip domain proteins (CASPs) in the plasma membrane, at the site where the Casparian strip will form. Localized CASPs...
متن کاملA peptide hormone required for Casparian strip diffusion barrier formation in Arabidopsis roots.
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 required for contiguous Casparian strip formation in Arabidopsis roots. These peptide hormones, which we named Casparian strip integrity facto...

متن کاملFunctional and Evolutionary Analysis of the CASPARIAN STRIP MEMBRANE DOMAIN PROTEIN Family.
CASPARIAN 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 of CASP-like (CASPL) proteins. CASPLs were found i...

among other things, a paleobotanist and an evolutionary biologist, and he is clearly in his element here as he ranges from the enigmatic origin of the Ginkgo alliance at least 220, and probably 245, million years ago, through its evolutionary radiation to become an important tree in appropriate habitats in temperate regions worldwide, to its subsequent decline in diversity and geographical rang...
