Wild crop relatives are valuable genetic resources for improving stress adaptation in cultivated species, but their effective use depends on high-quality reference genomes integrated with phenotyp...

Cytokinesis is a key process in the development of multicellular organisms, through both formative and proliferative divisions. In land plants, successful cytokinesis requires precise targeting of Golgi-derived vesicles to the future cell division plane by the phragmoplast, a cytoskeletal structure that undergoes continuous remodeling. Endomembrane trafficking and phragmoplast remodeling are tightly coupled, indicating the existence of active crosstalk. However, although many molecular regulators of membrane trafficking and cytoskeletal organization are known, it remains poorly understood how these processes are coordinated. Here, we describe a regulatory module consisting of the membrane-associated GTPase RAB-A2a, cytoskeleton-associated Class II Kinesin-12 proteins, and the Fused kinase ortholog TIO. We provide evidence that the interaction between these molecules at the midzone, and differential functions of Class II Kinesin-12 members at the leading and lagging cell plate domains, are essential for cytokinesis initiation and progression in Arabidopsis by simultaneously targeting vesicles to the midzone and coupling phragmoplast remodeling to vesicle delivery.

S-acylation and lipid composition as well as oligomerization control the plasma membrane localization and the organization into nanodomains of the Arabidopsis Stomatin/Prohibitin/Flotillin/HflK/C (SP....
