Pathogenic Mechanism and Biological Control of Konjac Soft Rot Disease
摘要
Abstract
[Objective] The researchResults on biological control of konjac soft rot disease written by domestic and foreign scholars were reported. [Method] According to investigating domestic and foreign literatures in recent years, the research progress on pathogenic mechanism and biological control written by domestic and foreign scholars were reviewed and several assumptions on the control of konjac soft rot disease were put forward. [Result] The population regulation system of Erwinia carotovora was determined through further study on pathogenic mechanism of Erwinia carotovora pathogeny, that was, the bacteria could monitor the quantity change of itself or other bacteria on the surrounding environment according to the concn. of specific signal molecular and startup the related genes of bacteria to express to adapt changing environment. Erwinia carotovora had a series of excretion system. The system Ⅰ excreted protease from cytoplasm to extracellular and one step was taken in this process. The system Ⅱ excreted pectinase and cellulase by two steps, which was put an important role on pathogenic process. The pecti-nase was the most important enzyme in the pathogenic process. Initial success on controlling konjac soft rot disease by biological control was obtained in recent years and it was mainly using biocontrol bacteria, biocontrol fungi, plant active substance and plant genetic engineering for controlling konjac soft rot disease. [Conclusion] The research provided new thoughts and means for controlling konjac soft rot disease effectively.关键词
