XVI International Botanical Congess

Physiological studies suggested the interaction of actin filaments and microtubules in various plant cells. Although the presence of factor(s) to connect these two cytoskeletons is expected, studies in this line is sparse. The present study aims at identification of such factor(s), using cultured cells of tobacco. From the crude extract, we obtained a polypeptide (190kDa) which bound to both actin filament and microtubules. This polypeptide localized in spindle and midboy during cell division, but not during interphase.
