Research Abstract

The reorientation of cortical microtubules from transverse to longitudinal directions was induced by hypergravity, ethylene or aging. The transcript levels of γ-tubulin complex and katanin genes were increased transiently by both hypergravity and ethylene treatments, whereas a decrease in the transcript levels of MAP65 was induced by hypergravity, ethylene or aging in azuki bean epicotyls. These results suggest that the changes in the transcript levels of γ-tubulin complex, katanin and MAP65 are involved in the reorientation of cortical microtubules.
