Effects of cytoskeletal inhibitors on circular arrays of microtubules (MTs) and microfilaments (MFs) around the subapex of fern protonemata were examined. Colchicine and amiprophos-methyl disrupted arrays of MTs but not of MFs. By contrast, cytochalasin B disrupted both MF and MT arrays, suggesting the dependence of MT arrays on MFs.
