抗病原菌植物基因工程进展

Advances of plant genetic engineering in anti-microbial pathogens

植物病原菌给农林生产带来巨大的损失，植物基因工程在培育抗病原菌植物方面是传统育种技术的补充和发展，短短几年，在抗细菌和抗真菌植物基因工程方面出现了一些全新的成功策略，这些范例都是针对病原菌的生理结构、致病机理及与植物的相互关系。本文概括论述了这些策略的基本思路并对其局限性加以探讨。随着植物病理学、植物分子生物学和病原菌分子生物学的研究进展，新的抗性策略将会出现。

Plant microbial pathogens bring about great damage to agricultural and forestry economy every year. Plant genetic engineering is the complement and development of traditional breeding techniques in protecting plants against microbial disease. In recent years, novel strategies have been emerging for breeding antibacterial or antifungi plants in plant genetic engineering. These examples are based on the clarification of microbial physiologic structure, pathogenetic mechanism and plant-microbe interactions. Integration of these strageties should make further contributions to effective field resistance. Cloning of disease resistance genes, molecular dissection of signal transduction mechanism and identification of virulence genes will provide attractive new opportunities for enhancing crop protection.
