The functions of PEX genes in peroxisome biogenesis and pathogenicity in phytopathogenic fungi.

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.

[Micro-macroscopical identification of Siegesbeckiae herba].

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.
