plant drought tolerance

As the farmland is limited and the population continuously increases at present, the object in plant breeding is to breed crop varieties with relatively drought tolerance.

在耕地有限，人口不断增长的今天，培育耐旱能力相对提高的植物品种已成为植物分子育种工程的目标之一。

AM fungi enhances the uptake by plants of certain nutrients, promotes plant growth, improves plant tolerance to drought and toxicity of pollutants, defends plants against pathogens, and so on.

AM真菌能够提高植物对营养元素的吸收，促进植物生长，改善植物对干旱及毒性污染的耐受性，增强植物的抗病性等。

It's an important branch of plant research on stress resistance to enhance or improve the capability of drought and water deficit-tolerance in plant.

改善和提高植物的抗旱性研究是植物抗逆性研究的重要内容。
