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.

皮质微管从横向到纵向的重新定向是由超重力、乙烯或衰老引起的。超重力和乙烯处理使γ-微管蛋白复合物和katanin的转录水平短暂增加，而MAP65的转录水平降低。由超重力、乙烯或小豆上胚轴老化引起的这些结果表明，γ-微管蛋白复合物的转录水平发生变化。 katanin 和 MAP65 参与皮质微管的重新定向。
