1·The pleiotropy of the five well-studied plant hormones is somewhat analogous to that of certain hormones in animals.

这五种已得到充分研究的植物激素的多效性在某种程度上类似于动物中某些激素的多效性。

2·Unlike the oligosaccharins, the five well-known plant hormones are pleiotropic rather than specific; that is, each has more than one effect on the growth and development of plants.

与氨基寡糖素不同，这五种众所周知的植物激素是多效性的，而不是特异性的；也就是说，每一种对植物的生长发育都有不止一种作用。

3·There are indications that pleiotropic plant hormones may actually function by activating the enzymes that release these other, more specific chemical messengers from the cell wall.

有迹象表明，多效性植物激素实际上可能通过激活酶来发挥作用，这些酶从细胞壁释放出这些更为特殊的化学信使。

4·Signal transduction pathways of plant hormones and their cross-talks;

植物激素信号传导及相互作用的分子机制；

5·Ethylene is one of the important plant hormones. It has significant physiological role in the life of plant.

乙烯是一种重要的植物激素，参与植物许多生理过程。

6·Ethylene is one of the important plant hormones, it has significant physiological role in the life of plant.

乙烯是一种重要的植物激素，参与植物整个生理过程。

7·In general, plant hormones are small molecules that probably act on target cells much the way animal hormones do.

通常，植物激素和动物激素相似，是作用与目标细胞的小分子化合物。

8·Auxin is one of the most important plant hormones in that it regulates almost all aspects of plant growth and development.

生长素是最重要的植物激素之一，参与了植物生长发育的各个方面。

9·On the basis of these experiments, the paper determined the contents of endogenous plant hormones levels in hardwood and shoot cuttings.

本文在此试验的基础上，对嫩枝和硬枝插穗中内源植物激素水平进行了测定。

10·On the basis of these experiments, this paper determined the contents of endogenous plant hormones levels in hardwood and shoot cuttings.
