Formins are well-known as important regulators participating in the organization of the actin cytoskeleton in organisms. For many years in the past, research on plant formins is more difficult than that in other eukaryotic formins and is limited to class I formins. Nevertheless, positive progress has been made in plant formin research recently, especially the investigations on class II formins. New functions of plant formins are identified gradually, such as regulating cell division and… Expand
Plant formins: membrane anchors for actin polymerization.
TLDR
Plants have a diverse family of formins and this diversity arose early in land plant evolution, probably deriving from family expansion and domain acquisition and the focus of these studies is beginning to shift from biochemical characterization to in vivo function. Expand
Formins: Emerging Players in the Dynamic Plant Cell Cortex
TLDR
Plant formins present good candidates for possible mediators of coordination of the cortical actin and microtubule cytoskeletons, as well as their attachment to the plasma membrane, that is, aspects of cell cortex organization likely to be important for cell and tissue morphogenesis. Expand
Formins: Linking Cytoskeleton and Endomembranes in Plant Cells
TLDR
It is proposed that, despite some methodological pitfalls inherent to in vivo studies based on (over)expression of truncated and/or tagged proteins, formins are beginning to emerge as candidates for the so far somewhat elusive link between the plant cytoskeleton and the endomembrane system. Expand
Formins and membranes: anchoring cortical actin to the cell wall and beyond
TLDR
FYVE, SH3 and BAR domain-containing proteins emerge as possible candidates for such conserved membrane-associated formin partners as well as other “non-classical” formin-membrane interactions. Expand
Chapter 2 Actin-Microtubule Interaction in Plants
Interactions between actins and microtubules play an important role in many fundamental cellular processes in eukaryotes. Although several studies have shown actins and microtubules to be involved inExpand
Emerging roles for microtubules in angiosperm pollen tube growth highlight new research cues
TLDR
A review of microtubules in secretion and endocytosis is examined, highlighting new research cues regarding cell wall construction and pollen tube-pistil crosstalk that help unravel the role of MTs in polarized growth. Expand
Cytoskeletal organization in isolated plant cells under geometry control
TLDR
An experimental approach to explore the relative contribution of geometry to the final organization of actin and microtubule cytoskeletons in single plant cells shows that, in cells constrained in rectangular shapes, the cytoskeleton align along the long axis of the cells. Expand
Cytoskeletal organization in isolated plant cells under geometry control
TLDR
The relative contribution of geometry to the final organization of actin and MT cytoskeletons in single plant cells of Arabidopsis thaliana is explored and it is shown that the cytoskeleton aligns with the long axis of the cells and that actin organization relies on MTs but not the opposite. Expand
Cytoskeletal and membrane dynamics during higher plant cytokinesis.
TLDR
This review focuses on the temporal and molecular requirements of cytokinesis in somatic cells of higher plants gleaned from recent studies using cell biology, genetics, pharmacology and biochemistry. Expand
Arabidopsis FH1 Formin Affects Cotyledon Pavement Cell Shape by Modulating Cytoskeleton Dynamics.
TLDR
Observations indicate that FH1 participates in the control of microtubule dynamics, possibly via its effects on actin, subsequently influencing cell morphogenesis and macroscopic organ development. Expand

Remodeling the cytoskeleton for growth and form: an overview with some new views.
TLDR
This review seeks to integrate current information about cytoskeletal components in plants and the role they play in generating cell form by evaluating the most recent work on the signaling mechanisms that continually remodel the actin cytoskeleton via the activation of actin-binding proteins (ABPs).

On the basis of structural and mechanistic work, an integrated model is presented for FH2 processive motion and the signature formin homology 2 (FH2) domain initiates filament assembly and remains persistently associated with the fast-growing barbed end, enabling rapid insertion of actin subunits while protecting the end from capping proteins.
