Abstract

Actin cytoskeleton organization in cells of planktonic armored dinoflagellate Prorocentrum minimum after treatment with the actin‐depolymerizing agent latrunculin B (1st and 3rd columns) and without it (2nd and 4th columns). Distribution of F‐actin was detected by staining with TRITC‐phalloidin, distribution of G‐actin ‐ by fluorescent deoxyribonuclease I. The well‐stained F‐actin cortical layer was observed in native cells; it disappeared and actin collapsed in treated cells. A clear staining of the cytoplasm and nucleus, with very intensely stained nucleolus, was observed both in cells incubated with latrunculin B and in untreated cells.
