Abstract:

Peroxisomes are cellular organelles present ubiquitously in eukaryotic cells and are involved in β-oxidation, glyoxylate cycle and a variety of biochemical metabolisms. Recently peroxisomes have been demonstrated to play vital roles in the host infection processes by plant fungal pathogens. The biogenesis of peroxisomes requires a category of proteins named peroxins, which are encoded by the PEX genes. So far, more than 10 PEX genes were isolated in phytopathogenic fungi, and significant research efforts are focused on the mechanism of peroxisome formation and the roles of peroxisome in the development and pathogenicity of fungal pathogens. In this review, we summarize the latest advances in peroxisome biogenesis and functions in pathogenic fungi, including the roles of PEXs in life cycle of peroxisome, peroxisome related metabolisms, and fungal development, infection and pathogenicity, in order to provide references for future studies in plant pathogenic fungi and the control of disease.

Key words: peroxisomes, PEX genes, phytopathogenic fungi, pathogenicity
