Identification of Key Regulatory Pathways of Basidiocarp Formation in Pleurotus spp. Using Modeling, Simulation and...

Area of Science:

• Mycology
• Plant Biotechnology
• Computational Biology

Background:

• Oyster mushrooms (Pleurotus) are globally cultivated edible fungi with therapeutic properties.
• Effective cultivation requires understanding intrinsic-extrinsic factors and genotype-environment interactions.
• Basidiocarp formation, crucial for mushroom yield, is complex and influenced by multiple variables.

Purpose of the Study:

• To explore basidiocarp formation biology in Pleurotus mushrooms.
• To investigate the in silico response to environmental factors and identify key regulatory genes.
• To develop a predictive model for understanding mushroom development.

Main Methods:

• In silico analysis of Pleurotus mushroom development.
• Development of a predictive model for basidiocarp formation.
• Identification and analysis of major regulatory genes involved in fruiting.

Main Results:

• The predictive model highlights key regulatory pathways in pinhead to fruit body development.
• White Collar protein 1 (PoWC1) binding to flavin-adenine dinucleotide (FAD) activates respiratory enzymes.
• PoWC1 and pofst genes are involved in structural changes, PoWC1 in respiration, and OLYA6 triggers fruiting.

Conclusions:

• Cell differentiation and high respiratory enzyme expression are critical for basidiocarp formation.
• Specific genes like PoWC1 and OLYA6 play significant roles in Pleurotus fruiting.
• Findings can advance sustainable mushroom cultivation through a deeper understanding of developmental mechanisms.
