Genome-wide identification and expression analyses of C2H2 zinc finger transcription factors in Pleurotus ostreatus

Summary

This research identified and characterized important regulatory genes called C2H2 zinc finger proteins in oyster mushrooms (Pleurotus ostreatus). These genes help control mushroom growth and development, as well as responses to environmental stresses like heat and cold. Understanding these genes could help improve mushroom cultivation. Impacts on everyday life: – Could lead to better mushroom varieties that are more resistant to temperature stress – May help develop mushrooms that grow more efficiently for improved food production – Could enable better control over mushroom growth timing and development – May contribute to more sustainable and reliable mushroom farming methods – Could help reduce crop losses due to environmental stresses during cultivation

Background

C2H2-type zinc finger proteins (C2H2-ZFPs) are important transcription factors that regulate various developmental processes and abiotic stress responses in eukaryotes. While these proteins have been studied in other organisms, a comprehensive analysis of C2H2-ZFPs has not been performed in Pleurotus ostreatus, an economically important edible mushroom species.

Objective

To identify and characterize C2H2 zinc finger transcription factors in the P. ostreatus genome and analyze their expression patterns during different developmental stages and in response to hormones and environmental stresses. The goal was to find candidate genes related to development control and abiotic stress tolerance.

Results

The study identified 18 C2H2-ZFPs in the P. ostreatus genome, which were clustered into four separate clades. The proteins showed diverse structural and physicochemical properties. Expression analysis revealed that these genes are differentially expressed during various developmental stages and respond to hormone treatments and environmental stresses. Several genes showed specific expression patterns during mycelial growth, primordia formation, and fruiting body development.

Conclusion

The identified C2H2-ZFPs in P. ostreatus have diverse structural characteristics and expression patterns, suggesting varied roles in tissue growth, development, hormone signaling, and abiotic stress responses. These findings provide valuable information for understanding C2H2-ZFPs in mushrooms and identify candidate genes for controlling development and stress tolerance in P. ostreatus.
