拟南芥信号传递途径

Constructing Signal Transduction Pathways in Arabidopsis

探讨拟南芥发育过程中一些调控基因表达的信号是如何传递的。广泛查阅近期有关发育生物学方面的文章 ,综述了拟南芥信号传递的过程。发现植物体有许多与动物相同的信号传递途径 ,如磷酸化级联途径。在拟南芥中Raf1激酶 ,蛋白激酶 (MEK)、蛋白激酶激酶 (MAPK)都与信号转导直接有关。另外发现磷酸化过程在一定程度上依赖于卷须蛋白 (CLV1)的自动磷酸化。植物信号转导途径类似于动物 ,通过磷酸化作用传递各种信号 ,来保持细胞增殖和分化的平衡。

To investigate the developmental processes of Arabiodopsis and how the signal of regulating development transducts the special gene. By looking up the recent literatures dealt with developmental biology, and reviewing several transduction pathways in Arabidopsis. Many signal transduction pathways in plant cells are familiar with that in animal cells. There is a phosphorylatin cascade. Raz, MEK and MAPK are also directly related to the signal transduction. In addition, to some extent, the phosphorylation process depends on the auto phosphorylatin of CLV proteins. Plants, like animals, transduct all kinds of signals by phosphorylation to balance the processes of cell proliferation and differentiaion.
