Plant cell morphogenesis requires precise regulation of localized cell expansion and cell division. Vectorial exocytosis is a major morphogenetic process in plant cells, intimately interwoven with the dynamics of the cytoskeleton. Small GTPases of the Ras superfamily act as molecular switches participating in the control of both vesicle trafficking (Rab(More)
The actin cytoskeleton plays a central part in the dynamic organization of eukaryotic cell structure. Nucleation of actin filaments is a crucial step in the establishment of new cytoskeletal structures or modification of existing ones, providing abundant targets for regulatory processes. A substantial part of our understanding of actin nucleation derives(More)
