ABSTRACT
Peroxisomes are cellular organelles present ubiquitously in eukaryotic cells and are involved in ß-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.

OBJECTIVE: To comprehend the connections and differences of the three sources of Siegesbeckiae Herba. METHOD: Using traditional Chinese medicine micro-macroscopical identification to identify these three sources of Siegesbeckiae Herba. RESULT: Three sources of Siegesbeckiae Herba are obviously different when using micro-macroscopical identification. CONCLUSION: Micro-macroscopical identification can distinguish three sources of Siegesbeckiae Herba veritably and directly.
