Complete mitochondrial genomic sequence of Auricularia delicata (Auriculariaceae), an edible Chinese mushroom

Summary

Scientists have sequenced the complete mitochondrial genome of Auricularia delicata, a popular edible jelly mushroom used in Chinese cuisine and traditional medicine. The genome is 189,696 base pairs long and contains 60 genes. This genetic information helps scientists understand how A. delicata is related to other mushroom species and provides a valuable resource for future research and cultivation of this important fungal species.

Background

Auricularia delicata is an edible and medicinal jelly mushroom popular in China and other regions of Africa and eastern Asia. There are few published Auricularia mitochondrial genome assemblies available for study. Understanding the genomic structure of this economically important fungal species is important for its continued study and utilization.

Objective

To report the assembly and annotation of a complete A. delicata mitochondrial genome and analyze its phylogenetic relationships with other Agaricomycetes species. This work aims to provide an invaluable reference for the continued study and utilization of A. delicata and other Auricularia species.

Results

The complete circular A. delicata mitochondrial genome is 189,696 bp in length with 34.1% GC content and contains 60 genes including 32 protein-coding genes, 26 tRNA genes, and two rRNA genes. Phylogenetic analysis showed A. delicata clustered with the Auricularia group alongside A. auricula-judae and A. heimuer with 100% bootstrap support. The A. delicata mitochondrial genome was larger than A. auricula-judae (40,586 bp) but smaller than A. heimuer (209,153 bp).

Conclusion

The complete A. delicata mitochondrial genome has been successfully assembled and annotated, providing a valuable reference for future research. This genome will aid in resolving the phylogeny of Auricularia species and support continued study and utilization of A. delicata and related species. The availability of this mitochondrial genome sequence contributes to the growing resources for Auricularia genomic research.
