Differential Protein Expression Profiling in Pleurotus ferulae Mycelium Caused by Asafoetida Extracts Using a Proteomics Approach

다국어 초록 (Multilingual Abstract)

The precise mechanism by which asafoetida extract influenced the growth of Pleurotus ferulae mycelium was investigated using a comparative proteomic analysis approach. Two types of asafoetida extracts were added to the medium of P. ferulae, and the effects of the extract on microstructure of P. ferulae mycelium were observed. Compared to the control group, the two asafoetida extracts played a significant role in promoting the growth of P. ferulae. Two-dimensional electrophoresis and LC-MS/MS were performed to examine changes in the expression of proteins in the mycelium of P. ferulae. A total of eight differentially expressed proteins were identified, including a heat shock protein, a flavin-containing monooxygenase, and a NADPH: quinone oxidoreductase type IV, as well as hypothetical and unknown proteins. Expression change of these proteins confirmed that asafoetida extracts significantly affected P. ferulae growth, metabolism, and secondary product metabolism. These results provide new insights into biochemical mechanisms underlying the relationship between P. ferulae and asafoetida.
