2+] in cytoplasmic streaming in a variety of plant tissues has been actively researched (Seagull, 1989), including some information available on root hairs.
Verapamil applied to root hairs of tomato and oilseed rape caused a cessation in cytoplasmic streaming within approximately 4 minutes but a recovery if no additional verapamil was added; addition of m-N-ethylmaleimide caused membrane depolarization and irreversible cessation of cytoplasmic streaming in these same species (Clarkson et al.

For example, it has been known for years that auxin affects cytoplasmic streaming in root hairs (Sweeney, 1944); if auxin action is mediated by [Ca.
1993) studied the effects of ammonium, nitrate, and aluminum on cytoplasmic streaming in wheat (Triticum aestivum) root hairs.
