Researchers studied how a special strain of Sarcomyxa edulis (a tasty edible mushroom from Northeast China) develops fruiting bodies by analyzing which genes are turned on and off during this process. By comparing immature mycelium with developing fruiting bodies, they identified key genes responsible for cell division, DNA repair, and energy metabolism that control fruiting body formation. This knowledge can help mushroom farmers improve yield and quality through better understanding of how mushrooms grow. The findings provide a foundation for developing better cultivation techniques and selecting superior mushroom strains for commercial production.
