摘要:

近年来林木与病原菌互作的分子机制研究成果丰硕,尤其是HIGS与CRISPR/Cas9等技术的发展,促进了林木病原菌关键致病基因的功能、病原菌基因组与转录组学、病原菌效应蛋白、林木抗病基因功能、林木抗病与生长平衡、林木抗病分子育种等多个层面研究的快速发展。从植物-病原菌分子互作的基本问题出发,综述了国内外林木-病原菌分子互作机制研究的进展与热点,包括病原菌侵入过程的信号网络及功能、病原菌活性氧解毒机制及效应蛋白的多种作用机制、林木与病原菌的组学研究进展、林木关键防御机制、林木与内生真菌及外生真菌互作机制等。基于目前的研究进展,对未来林木-病原菌分子互作的发展趋势进行了展望,“Zigzag”理论、“诱饵”假说这些新理论,高效的测序技术及分子操作等新技术, 效应蛋白及免疫受体互作等新方向的出现也预示着林木-病原菌互作研究开始迈入新的阶段。

Abstract:

In recent years, great achivements have been made on the study of the molecular interaction between forest trees and phytopathogens. Particularly, thanks to the novel technology including HIGS and CRISPR/Cas9, there are many breakthroughs towards the functional analysis of key virulence-related genes, pathogen genome and transcriptome analysis, pathogenic effector protein analysis, functional analysis of R gene in forest trees, the balance between disease resistance and growth and molecular breeding for disease control. This paper starts with the basic issue of molecular plant-pathogen interaction currently and reviews the current progress and hotspots of molecular interaction between forest trees and pathogens, including the signal network of pathogen invasion, the detoxification mechanism of reactive oxygen species and the multiple action mechanisms of effector proteins, the research progress of omics between trees and pathogens, the key defense mechanism of trees, the interaction mechanism between trees and endophytic fungi and exophytic fungi, and so on. Based on the current research progress, we prospect the future development trend of tree-pathogen molecular interaction. At the same time, the emergence of new theories such as the Zigzag model and Decoy hypothesis, new technologies such as efficient sequencing and molecular manipulation, and new research directions such as effector protein and immune receptor interaction indicate a whole new stage of forest trees and pathogen interactions.

Key words: forest trees immunity, molecular breeding, molecular interaction, phytopathogen, effector
