6.3. ADF
Although plant ADF, and proteins that control the activity of
ADF, differ somewhat from animal ADF [106], plant ADF has
been shown to increase the turnover of actin filaments, as
animal ADF does. Indeed, microinjection of pollen-specific
ADF in Tradescantia stamen hair cells led to the depolymerisation
of F-actin in cytoplasmic strands, which caused cytoplasmic
strands to disappear [11]. When ADF is overexpressed in
Arabidopsis, thick actin bundles disappear in different cell
