超重力、乙烯或老化可引起皮质微管从横向向纵向的重新定位。γ-微管蛋白复合体和katanin基因的转录水平在超重力和乙烯处理下都瞬时升高,而MAP65基因的转录水平在超重力、乙烯或老化处理下降低。这些结果提示,γ-微管蛋白复合体、katanin和MAP65转录水平的变化参与了皮质微管的重定向。
英文摘要
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.
