August 2024 in “International Journal of Molecular Sciences” This study found that root hairs of wild-type Arabidopsis grow faster and longer under low potassium stress, with changes in actin filament dynamics and specific regulation by the actin bundling proteins VLN1 and VLN4.
This study found that the protein Formin 2 helps regulate cell-to-cell transport in thale cress by stabilizing actin filaments at plasmodesmata, with its absence leading to increased permeability and vulnerability to viral infections.
This study found that the Arabidopsis thaliana protein Formin 2 localizes to plasmodesmata and is crucial for regulating their permeability by anchoring actin filaments, which affects virus susceptibility.

March 2019 in “The Journal of Cell Biology” This study identified that the Wave complex proteins ABI1 and Wave2 play a crucial role in regulating epidermal shape and growth during skin development, notably influencing SOX9 expression and Wnt signaling pathways.
December 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” This study observed that in live rodents, actin filaments adjust their structure to facilitate membrane transfer between cellular compartments; linear filaments stabilize fused membranes, while branched filaments, connected by the protein Ezrin, drive integration, demonstrating actin's role in adapting to membrane biophysical changes.
