E. Hilaire et al., CORTICAL MICROTUBULES IN SWEET CLOVER COLUMELLA CELLS DEVELOPED IN MICROGRAVITY, Plant and Cell Physiology, 36(7), 1995, pp. 1387-1392
Electron micrographs of columella cells from sweet clover seedlings gr
own and fixed in microgravity revealed longitudinal and cross sectione
d cortical microtubules. This is the first report demonstrating the pr
esence and stability of this network in plants in microgravity.
