Abstract

Actin filaments in cultured tobacco cells were stained by rhodamine-phalloidin after pretreatment with 100 μM m-maleidobenzoyl N-hydroxysuccinimide ester (MBS) followed by formaldehyde fixation. The use of MBS prior to formaldehyde fixation enabled us to visualize fine, transversely arranged cortical actin filaments in a majority of interphase tobacco cells. It also enabled us to double-stain fine actin filaments and microtubules in the same cells. The pattern of actin filaments and that of microtubules in the cortical region of a single tobacco cell bore a close resemblance to each other. The method which employed MBS was found to be useful also in visualizing fine cortical actin filaments in inner epidermal cells of onion bulbs.
