Anti-fungal Activity of Dalbergia retusa Extract on Gloeophyllum trabeum

Hongmu is a type of material with strong corrosion resistance, and its extract has wood preservative properties in a variety of environmental settings. Herein, the processing residue of Dalbergia retusa was used to obtain an ethanol-extract, whose anti-fungal properties and mechanism was investigated using multi-omics principles and gas chromatography-mass spectrometry (GC-MS). The results show that D. retusa extract had a strong inhibitory effect on decaying fungus, and the inhibitory effect was dose dependent. High-throughput sequencing detected a total of 11,755 genes for transcriptome comparison. A total of 390 genes were differentially expressed, with 69 up-regulated and 321 down-regulated genes, indicating that D. retusa extract can significantly affect metabolic processes in decaying fungus. GC-MS results revealed that D. retusa extract was rich in phenols, ketones, amines, and aromatic compounds, which are likely to contribute to the excellent synergy between anti-fungal properties and anti-fungal activity (anti-fungal ability and active ingredients). In summary, this study describes the anti-fungal components in D. retusa extract, and our results provide a foundation for the study of their mechanism of action in this tree species.

Automated summary

This study investigates the anti-fungal properties and mechanism of Dalbergia retusa extract, obtained from the processing residue of the wood. The results demonstrate the strong inhibitory effect of the extract on decaying fungus, and suggest a dose dependent relationship. Transcriptome comparison and GC-MS analysis provide insights into the potential mechanism of action, highlighting the richness of compounds in the extract.
