In potato roots, the endodermis and exodermis define anatomical compartments for mineral nutrients. Exodermal suberin accumulates early, and its reduction

In roots, the endodermis controls nutrient entry by forming a barrier known as the Casparian strip. Yet how barrier-associated processes interface with systemic signaling remains unclear. Here, we sho...

Using cryo-electron tomography, the authors reveal how plasmodesmata (plant cytoplasmic bridges) are gated by cell wall remodelling and how helical protein assemblies scaffold internal membranes, with...

Ultrastructural studies by Bonnett and Newcomb in 1966 revealed the existence of coated vesicles budding from the plant cell plasma membrane. This review introduces this discovery and early questions...

This study reveals that enhanced autophagy in root-hair-forming cells helps Arabidopsis store excess sodium, control oxidative stress and tolerate salt stress.

Nature Plants - A genetic screen across Arabidopsis accessions identifies SBG1 as a regulator of root abscisic acid response and endodermal suberin deposition via type 1 protein phosphatases,...

Cell shape acquisition is a central feature of morphogenesis, governing tissue organization, organ development, and organismal architecture. In vascul…
