Summary
This research investigated how blue light affects the growth of oyster mushroom tissue and identified specific genes that respond to light exposure. This has important implications for mushroom cultivation and our understanding of how fungi respond to environmental signals. Impact on everyday life:
• Could help optimize commercial mushroom growing conditions
• Advances our knowledge of light’s effects on fungal growth
• May lead to improved mushroom cultivation techniques
• Could inform better indoor farming practices
• Helps understand natural mushroom growth patterns
Background
Light quality, intensity and cycles can affect mushroom mycelial growth, but the genetic mechanisms behind blue light responses in oyster mushrooms were not well understood.
Objective
To identify and characterize genes that are regulated by blue light exposure in oyster mushroom mycelia using LED light stimulation and molecular analysis techniques.
Results
The study identified 15 upregulated and 13 downregulated genes induced by blue-light stimulation. Blue light was found to suppress mycelial growth in a light intensity-dependent manner. Expression analysis revealed distinct induction timing patterns for eight of the identified genes.
Conclusion
This research provided the first identification of specific genes regulated by blue light in oyster mushroom mycelia, demonstrating that blue light exposure triggers both up and down regulation of multiple genes with distinct temporal expression patterns.
