Abstract:

Peroxisome are multifunctional and dynamic organelles essential for the development in most of the eukaryotes. In fungi, the organelles are involved in divers growth and development processes, including sexual reproduction. The formation of fungal sexual spores, usuallyoccurs in multicellular fruiting bodies, requires multiple steps such as mitosis, meiosis, cell differentiation. Studies have shown that peroxisomes play a role in regulating the above processes and are necessary for sustaining the formation of fruiting bodies, the production and the maturation of sexual spores. Firstly, the morphogenesis of fungal sexual reproduction depends on the degradation of lipid reserves in mycelial cells to supply energy and intermediate molecules, while the fatty acid β-oxidation and the glyoxylate cycle in peroxisomes are necessary steps for lipid degradation and transformation. Secondly, peroxisomes may also be directly involved in the processes of cell meiosis. During cell meiosis, the size, quantity and location of peroxisomes change regularly. In addition, peroxisomes also participate in the formation of signaling molecules during sexual reproduction, and the knockdown of peroxisomal biogenesis-related genes affects the formation of fungal perithecium.
