Microbial toxin contamination in food and its harm to human body were described inthis paper

本文概述了微生物毒素对食品的污染及其对人体健康的危害。

Growth degeneration and yield declination are becoming obvious after a long term continuous cropping of crops, vegetables, fruit trees and nursery seedlings. Many studies show that soil ecological environment greatly affect the growth of plant under continuous cropping, and particularly, the decomposition products of plant residues and pathogenic microbes have a toxic effect to plants and affect the normal metabolism of root exudates, producing an auto toxic effect.In this paper, the rhizospheric effects...

Growth degeneration and yield declination are becoming obvious after a long term continuous cropping of crops, vegetables, fruit trees and nursery seedlings. Many studies show that soil ecological environment greatly affect the growth of plant under continuous cropping, and particularly, the decomposition products of plant residues and pathogenic microbes have a toxic effect to plants and affect the normal metabolism of root exudates, producing an auto toxic effect.In this paper, the rhizospheric effects of soil environmental factors (air,moisture, nutrient and microorganisms), active substances (phytotoxin, residue decomposition substances, microbial toxin), and pathogenic microbes on root exudates under conditions of continuous cropping were systematically introduced, which would afford inspiration for further studying on the interaction mechanism between root exudates and continuous cropping obstacle.

作物、蔬菜、果树以及苗木长期连作后,皆出现生长衰退和产量降低.许多研究结果表明,连作条件下土壤生态环境对植物生长有很大的影响,尤以植物残体与病原微生物的分解产物,对植物有致毒作用,并影响植物根系分泌物正常代谢,以致于发生自毒作用.本文围绕根系分泌物与根际微生态的相互关系,系统地介绍连作障碍条件下,影响根系分泌物的环境因素(土壤空气、湿度、养分与微生物)、活性物质(自身毒素、残体分解物、微生物产生毒素)、土壤病原菌等的根际效应,为深入研究根系分泌物与连作障碍的相互作用机制提供启示.

The genetic engineering of plant proteinase inhibitor (PI) provides a novel approach, in addition to that of microbial toxin protein genes, for improving plant resistance to insect pests. In camparison with other insecticidal proteins wildly used in the world, especially Bt endotoxins, the plant PI possesses some distinctive advantages such as hard to produce tolerance, broad target spectrum , inductive enhancement, and not so much gene modification, etc. While the resistance mechanism of Pis to insect...

The genetic engineering of plant proteinase inhibitor (PI) provides a novel approach, in addition to that of microbial toxin protein genes, for improving plant resistance to insect pests. In camparison with other insecticidal proteins wildly used in the world, especially Bt endotoxins, the plant PI possesses some distinctive advantages such as hard to produce tolerance, broad target spectrum , inductive enhancement, and not so much gene modification, etc. While the resistance mechanism of Pis to insect pests is not so clear so far, and there are a number of factors affecting on their insecticidal actions. In this paper, the recent progress of the studies on insect resistance functions and mechanisms was cited and analyzed, and the problems and solutions in plant PI genetic engineering were discussed.

蛋白酶抑制剂抗虫基因工程为提高植物的抗虫能力提供了一种新的策略。与其它来源的抗虫蛋白相比,植物蛋白酶抑制剂有很多独特的优点。蛋白酶抑制剂的抗虫机理尚不完全清楚,影响其抗虫效果的因素也很多。文中列举并分析了PI抗虫作用的机理以及目前研究的新进展,提出植物蛋白酶抑制剂抗虫基因工程中存在的问题和进一步解决的办法。
