Summary
Blue light significantly enhances the yield and quality of Hericium coralloides mushrooms by influencing gene expression. This finding suggests blue light could optimize cultivation practices for this traditional edible and medicinal fungus.
Area of Science:
- Mycology
- Plant and Fungal Biology
- Biotechnology
Background:
- Hericium coralloides is a traditional edible and medicinal mushroom.
- Light is a critical factor in fungal fruiting body development.
- The specific effects of different light spectra on H. coralloides yield and morphology were previously unknown.
Purpose of the Study:
- To investigate the impact of blue, red, and white light on the morphology, yield, and transcriptome of Hericium coralloides.
- To understand the molecular mechanisms underlying light-induced changes in H. coralloides.
Main Methods:
- Cultivation of H. coralloides under controlled blue, red, and white light conditions.
- Morphological assessment of fruiting bodies.
- Transcriptome analysis using RNA sequencing.
- Gene Ontology (GO) enrichment analysis.
Main Results:
- Blue light exposure resulted in superior fruiting body morphology (color, size, stalk elongation, spine count) and increased yields.
- Significant transcriptome alterations were observed under different light conditions, with blue light inducing 10,827 differentially expressed genes (DEGs) and red light inducing 11,375 DEGs.
- Light influenced nearly all biological processes in H. coralloides, with blue light potentially enhancing yield by upregulating growth-related processes like DNA replication and cell division.
Conclusions:
- Blue light plays a significant role in modulating gene expression and stimulating yield in Hericium coralloides.
- The findings provide preliminary insights for optimizing H. coralloides cultivation practices through light manipulation.
- The study highlights the underestimated influence of light on fungal biology.
