植物病原真菌过氧化物酶体的发生机制及功能

Biogenesis and functions of the peroxisome in phytopathogenic fungi-A review

过氧化物酶体(peroxisome,P)是真核细胞中普遍存在的细胞器,参与多种重要的代谢过程。P的产生、增殖及降解是细胞器发生机理研究的重要部分。到目前已知的P发生相关基因有30多个,但其机制仍不完全清楚。作为一种多细胞真核生物,丝状真菌在P发生机制的研究中有重要价值。近年来,随着基因组序列的应用和真菌生物技术的进展,丝状真菌中P功能及发生机制的研究取得了较大进展。同时,作为丝状真菌真菌中的重要类群,植物病原真菌P在致病过程中的作用也引起关注。本文对P发生机制、在丝状真菌中的研究概况,以及与植物病原真菌致病性的关系进行了综述。

Peroxisome （P）, a ubiquitous organelle in the eukaryotic cells, is involved in various important metabolic processes. Investigation of formation, proliferation and degradation of the peroxisome is an important part of study of organelles biogenesis. So far, mechanism of the peroxisome biogenesis is not completely clear, although over 30 related genes were identified and characterized. Filamentous fungus, a multi-cellular eukaryotic organism containing many plant pathogens and economic species, holds great value of studying function and mechanism in the peroxisome biogenesis. The peroxisome researches have been progressed in recent years quickly after availability of the genome data and development of the fungal bio-techniques. Meanwhile greater interests have been demonstrated in area of the peroxisome biogenesis and in its roles of pathogenicity of several phytopathogenic fungi. The summary of mechanism of the peroxisome biogenesis in filamentous fungi and relationship between peroxisome and pathogenicity were reviewed in this paper.
