Summary
This research focused on improving the accuracy of genetic studies in shiitake mushrooms by identifying the most reliable reference genes for measuring gene expression. This is important because shiitake mushrooms have significant nutritional and medicinal properties that researchers are trying to understand better at the molecular level. Impact on everyday life:
– Helps develop more accurate methods for studying beneficial compounds in mushrooms
– Contributes to improving cultivation and quality of edible mushrooms
– Supports development of better medicinal compounds from mushrooms
– Advances our understanding of how mushrooms produce their health-beneficial substances
Background
Lentinula edodes (shiitake mushroom) is an economically important edible mushroom valued for its nutritional and medicinal properties. It contains various therapeutic compounds including polysaccharides, terpenoids, sterols, and lipids. Quantitative real-time PCR (qRT-PCR) is a powerful tool for analyzing gene expression and biosynthetic pathways, but requires proper reference genes for accurate data normalization.
Objective
To systematically evaluate and identify suitable reference genes for qRT-PCR data normalization in L. edodes under different experimental conditions including various strains, developmental stages, and nutrient conditions.
Results
Rpl4 was identified as the most stable reference gene across all experimental conditions. Atu was the most stable gene among strains, while 18S was found to be the best reference gene for different development stages. For nutrient conditions, Rpl4 showed the highest stability. F-actin and Pma were consistently ranked as the least stable genes. The validation experiment confirmed that using unstable reference genes led to misinterpretation of gene expression results.
Conclusion
This study provides the first systematic evaluation of reference genes for qRT-PCR in L. edodes. Different experimental conditions require different optimal reference genes for accurate normalization. The findings provide valuable guidelines for selecting appropriate reference genes for gene expression studies in L. edodes and establish a foundation for similar studies in other fungi.
