Interpretive Summary: Aspergillus flavus is a soilborne saprophyte capable of infecting important agricultural crops and producing aflatoxins. A. flavus isolate AF13 is a highly aflatoxigenic, L-strain isolate. A reference-quality, chromosome-level genome assembly has been published for AF13. Here, we report the complete mitochondrial genome for A. flavus AF13. The circular mitochondrial genome is 29,187 bp, encoding 14 protein-coding genes, 27 transfer RNA genes, and two ribosomal RNA genes. The A. flavus AF13 mitochondrial genome will be a valuable resource for respiration metabolism and fungicide resistance studies.

Technical Abstract: Aspergillus flavus contaminates crops by producing highly carcinogenic aflatoxins, posing significant economic and public health risks across the globe. Here, we report the complete mitochondrial genome of A. flavus AF13, a highly stress-tolerant and aflatoxigenic strain with an existing reference-grade chromosome-level nuclear genome assembly. The circular mitogenome is 29,187 bp with a GC content of 26.1%, encoding 14 protein-coding genes, 27 transfer RNA genes, and two ribosomal RNA genes. Pairwise alignment showed that the AF13 mitogenome had an average identity of 99.88% to 11 other A. flavus mitogenomes. The A. flavus AF13 mitogenome will be a valuable resource for respiration metabolism and fungicide resistance studies.
