Arabidopsis	At2g29890	Binds actin and actin bundles independently of Ca²⁺/calmodulin, but lacks filament-severing, capping and nucleation activities in vitro.	Arabidopsis VILLIN1 generates actin filament cables that are resistant to depolymerization.; 2005; DOI: 10.1105/tpc.104.028555; PMID: 15659626; https://pubmed.ncbi.nlm.nih.gov/15659626/ | Arabidopsis VILLIN1 and VILLIN3 have overlapping and distinct activities in actin bundle formation and turnover.; 2010; DOI: 10.1105/tpc.110.076240; PMID: 20807878; https://pubmed.ncbi.nlm.nih.gov/20807878/
Arabidopsis	At4g30160	Binds actin and actin bundles independently of Ca²⁺, but caps filament barbed ends and severs filaments in a calcium-dependent manner.	Arabidopsis VILLIN4 is involved in root hair growth through regulating actin organization in a Ca2+-dependent manner.; 2011; DOI: 10.1111/j.1469-8137.2010.03632.x; PMID: 21275995; https://pubmed.ncbi.nlm.nih.gov/21275995/ | The universal bundling activity of AtVLN4 in diffusely growing cells.; 2011; DOI: 10.4161/psb.6.9.16501; PMID: 22019634; https://pubmed.ncbi.nlm.nih.gov/22019634/
Arabidopsis	At5g57320	Major actin filament stabilizing factor and regulator of actin dynamics.	Arabidopsis VILLIN5, an actin filament bundling and severing protein, is necessary for normal pollen tube growth.; 2010; DOI: 10.1105/tpc.110.076257; PMID: 20807879; https://pubmed.ncbi.nlm.nih.gov/20807879/ | Arabidopsis villins promote actin turnover at pollen tube tips and facilitate the construction of actin collars.; 2013; DOI: 10.1105/tpc.113.110940; PMID: 23715472; https://pubmed.ncbi.nlm.nih.gov/23715472/
