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

Summary

Scientists have completely sequenced the mitochondrial DNA of Auricularia delicata, a popular edible jelly mushroom used as food and medicine in China and other Asian regions. The genome is 189,696 base pairs long and contains 60 genes. This genetic information helps researchers understand how this mushroom is related to other species and provides a reference for future studies on mushroom cultivation and properties.

Background

Auricularia delicata is an edible and medicinal jelly mushroom popular in China and other regions. There are few published Auricularia mitochondrial genome assemblies available. Understanding the phylogeny and evolutionary history of this economically important fungal species requires genomic data.

Objective

To report the assembly and annotation of the complete mitochondrial genome of Auricularia delicata. To provide genomic reference for continued study and utilization of A. delicata and other Auricularia species.

Results

The complete circular A. delicata mitochondrial genome is 189,696 bp with 34.1% GC content. It contains 60 genes including 32 protein-coding genes, 26 tRNA genes, and two rRNA genes. Phylogenetic analysis shows A. delicata clusters with the Auricularia group alongside A. auricula-judae and A. heimuer, and is genetically distant from other Polyporales, Russulales, and Agaricales species.

Conclusion

The first complete mitochondrial genome of A. delicata has been successfully sequenced and annotated. This genome provides an invaluable reference for phylogenetic studies and continued research on A. delicata and related Auricularia species.
