Abstract
The arrangements of cortical microtubules (MTs) in a tip-growing protonemal cell of Adiantum capillus-veneris L. and of cellulose microfibrils (MFs) in its wall were examined during blue-light (BL)-induced apical swelling. In most protonemal cells which had been growing in the longitudinal direction under red light, apical swelling was induced within 2 h of the onset of BL irradiation, and swelling continued for at least 8 h. During the longitudinal growth under red light, the arrangement of MFs around the base of the apical hemisphere (the subapical region) was perpendicular to the cell axis, while a random arrangement of MFs was found at the very tip, and a roughly axial arrangement was observed in the cylindrical region of most cells. This orientation of MFs corresponds to that of the cortical MTs reported previously (Murata et al. 1987, Protoplasma 141, 135–138). In cells irradiated with BL, a random rather than transverse arrangement of both MTs and MFs was found in the subapical region. Time-course studies showed that this reorientation occurred within 1 h after the onset of the BL irradiation, i.e. it preceded the change in growth pattern. These results indicate that the orientation of cortical MTs and of cellulose MFs is involved in the regulation of cell diameter in a tip-growing Adiantum protonemal cell.
