马铃薯致病疫霉拮抗细菌研究进展

为了解决马铃薯致病疫霉侵染马铃薯导致其死亡,进而造成马铃薯单位种植产量低的问题。本文从拮抗菌入手,归纳分析细菌类拮抗菌中的主要拮抗菌中芽孢杆菌、假单胞菌和粘细菌对马铃薯致病疫霉的抑制作用。同时,在总结前人研究的基础上,笔者认为在拮抗菌应用方面,可以采用多对一的新型平板对峙筛菌模式来模拟复杂条件下拮抗菌的拮抗作用,以期得到稳定的拮抗菌;并指出应从定植能力和根际微生物影响方面对拮抗菌实际应用的可行性进行研究;此外,提出未来对拮抗菌抑制马铃薯致病疫霉的探究应从表型层面的研究深入到分子层面,以期能成功从源头找寻抑制马铃薯致病疫霉的答案。

Antagonistic Bacteria of Phytophthora infestans in Potato: A Review

The aim is to solve the problem of death caused by Phytophthora infestans and low yield per unit in potato planting. In this paper, we started with antagonistic bacteria, summarized and analyzed the inhibitory effects of Bacillus, Pseudomonas and myxobacteria on Phytophthora infestans in potato. At the same time, based on the previous studies, in the application of antagonistic bacteria, we used the new many-to-one plate confrontation sieve model to simulate the antagonistic action of antagonistic bacteria, in order to get stable antagonistic bacteria. We pointed out that the feasibility of practical application of antagonistic bacteria should be studied from colonization ability and influence of rhizospheric microorganisms. In addition, we proposed that the future exploration of antagonistic antibacterial inhibition of potato Phytophthora infestans should go from the phenotypic level to the molecular level, in order to successfully find the answer from the source to inhibit Phytophthora infestans in potato.
