Proteome study of dikaryotic and monokaryotic mycelia reveals the transfer between biological processes contributing to dikaryon growth advantage of the medicinal fungus Ganoderma lucidum
Abstract Background Ganoderma lucidum, a well-known medicinal fungus in traditional Chinese medicine, exhibits a superior growth rate in its dikaryotic mycelia compared to monokaryons, and this is essential for its fruiting body formation and medicinal utilization. However, the biological process la...

| description | Abstract Background Ganoderma lucidum, a well-known medicinal fungus in traditional Chinese medicine, exhibits a superior growth rate in its dikaryotic mycelia compared to monokaryons, and this is essential for its fruiting body formation and medicinal utilization. However, the biological process landscape contributing to the dikaryon growth advantage remains largely unexplored. This study performed Tandem Mass Tag (TMT)-based proteomic analysis of the dikaryotic mycelia and two compatible monokaryotic mycelia to elucidate the mechanism underlying this growth advantage. Results Dikaryotic mycelia showed superior growth rates over monokaryons in both solid and liquid cultures. Proteomic analysis revealed a remodeled proteome of the dikaryon, with elevated expression levels of proteins involved in biosynthesis and processing of protein and RNA, cell structure, and cell division, compared to monokaryons, in both global proteins (3990) and differentially expressed proteins (983) analysis. In contrast, metabolism related proteins, particularly those involved in energy production and conversion, expressed at lower levels in dikaryon compared to monokaryons. Nonetheless, the energy-consuming proteins showed high expression in dikaryon. Conclusions These results indicate diverse remodeled biological processes coordinately contribute to the dikaryon growth advantage, especially the transfer from energy metabolism to biosynthesis and growth with high energy utilization efficiency. This is the first discovery of metabolic remodeling in dikaryotic mycelia of G. lucidum, presenting favorable implications for the breeding of G. lucidum. |
