| 中文摘要: |
| 在寄主与病原互作的研究中,通过分子生物学与生物技术成功分离和克隆了大量植物防御相关基因,这些基因的表达产物——蛋白、肽或抗菌素直接对病菌有毒害作用或在侵入位点抑制病菌的生长;直接抑制病菌的毒性产物或增强植物结构抗性基因,直接或间接活化植物整体防御反应;增强过敏性坏死反应中与无毒基因互作的抗性基因。将这些基因引入植物,转基因植物显示出对病原真菌明显的抑制作用,在提高植物抗性方面具有广阔的发展前景。 |
| 英文摘要: |
| Recent applications of techniques in plant molecular biology and biotechnology to the study of host-pathogen interactions have resulted in the identification and cloning of numerous genes involved in the defense responses of plants following pathogen infection. These genes that express proteins, peptides, or antimicrobial compounds are directly toxic to pathogens or reduce their growth in situ; directly inhibit pathogen virulence products or enhance plant structural defense genes, directly or indirectly activate general plant defense responses; and improve resistance genes involved in the hypersensitive response and in the interactions with avirulence factors. The introduction and expression of these genes in a range of transgenic plant species have shown that the development of fungal pathogens can be significantly reduced. Induced defense responses have the potential to provide useful broad-spectrum disease resistance. |
