Abstract Polyporus umbellatus is a precious medicinal fungus. The whole transcriptome of P. umbellatus exposed to different concentrations of oxalic acid was performed and analyzed using RNA-seq based on sequencing technology. Reactive oxygen species (ROS) detection of P. umbellatus mycelia was visually conducted and using non-invasive micro-test technology (NMT), the net Ca2+ and H2O2 fluxes of P. umbellatus were measured. Totally, 22,523 unigenes were generated by De novo assembly of reads and there are 1223 differentially expressed genes (DEGs) between the control group and the high oxalic acid complemented (PD_S) group and 459 DEGs between the control group and the low concentration oxalic acid additive (PU_SM) group. The transcriptomic analysis indicated DEGs encoding enzymes related to oxidative stress, energy metabolism and so on. Compared to that of the control group, the biomass of the sclerotia in the PU_SM group increased 66%, however, no sclerotia formed in the PD_S group. The low concentration of oxalic acid could increase Ca2+ and H2O2 influx, while the high concentration of oxalic acid presented slight H2O2 efflux. There is a great significant positive correlation between the net Ca2+ and H2O2 fluxes. Different concentrations of exogenous oxalic acid affected P. umbellatus sclerotial formation in different ways.

AbstractPolyporus umbellatus is a precious medicinal fungus. Oxalic acid was observed to affect sclerotial formation and sclerotia possessed more medicinal compounds than mycelia. In this study, the transcriptome of P. umbellatus was analysed after the fungus was exposed to various concentrations of oxalic acid. The differentially expressed genes (DEGs) encoding a series of oxidases were upregulated, and reductases were downregulated, in the low-oxalic-acid (Low OA) group compared to the control (No OA) group, while the opposite phenomenon was observed in the high-oxalic-acid (High OA) group. The detection of reactive oxygen species (ROS) in P. umbellatus mycelia was performed visually, and Ca2+ and H2O2 fluxes were measured using non-invasive micro-test technology (NMT). The sclerotial biomass in the Low OA group increased by 66%, however, no sclerotia formed in the High OA group. The ROS fluorescence intensity increased significantly in the Low OA group but decreased considerably in the High OA group. Ca2+ and H2O2 influx significantly increased in the Low OA group, while H2O2 exhibited efflux in the High OA group. A higher level of oxidative stress formed in the Low OA group. Different concentrations of oxalic acid were determined to affect P. umbellatus sclerotial formation in different ways.
