The complete mitochondrial genome sequence of Avena chinensis (Fisch. ex Roem. & Schult.) Metzg., 1824 (Poaceae)

Avena chinensis is an oat species with potential agricultural value and genetic resources for oat improvement. Here, we report its first mitochondrial genome assembly, represented as a circular sequence of 549,864 bp with a GC content of 44.17%. The mitogenome contained 54 genes, including 34 protein-coding genes, 17 tRNA genes, and three rRNA genes. Phylogenetic analysis showed that A. chinensis was sister to Avena longiglumis, with Poa pratensis representing the closest sampled intergeneric relative. This study provides a valuable genomic resource for the further utilization and evolutionary research of A. chinensis.
