Molecular mechanism of postharvest quality deterioration in Stropharia rugosoannulata based on transcriptomics and metabolomics.

Postharvest storage of Stropharia rugosoannulata involves 2,955 genes and 43 metabolites linked to key pathways like carbohydrate metabolism and cell wall degradation.

• Why it matters: Understanding the molecular mechanisms behind postharvest deterioration is crucial for improving shelf life and commercial value of this mushroom species.
• What they did: The study used transcriptome sequencing and untargeted metabolomics on cap tissues at three storage stages (0, 7, 14 days at 15°C), identifying differentially expressed genes and metabolites.
• The result: Findings reveal consistent expression trends in key enzyme genes and substrate levels within critical pathways, providing targets for postharvest preservation strategies.
