| 摘要: |
| 植物抗病性是寄主植物与病原物相互斗争中共同进化的结果。现代植物病理学研究的核心问题则是揭示寄主植物与病原物相互作用的本质,它涉及到寄主植物与病原物相互斗争中一系列复杂的细胞学、组织学以及生理学和生物化学的变化,而植物保卫素的研究恰恰反映了这一变化的一个十分引人注目的侧面。植物保卫素的研究已有四十多年的历史,虽然目前 |

| Abstract: |
| Phytoalexins as factors contributing to disease resistance have been studied for more than four decades.There can be no doubt that many plant-pathogens rapidly accumulate phytoalexin in response to infection. Generally,a possitive relationship may be observed,the phytoalexin occurring at times and places consistent with cessation of fungal growth,especially in the Leguminosae and the Solanaceae plants. Recently proposed definitions of phytoalexins areLow molecular weight antimicrobial compounds that are bot... |
