Mitochondrial Genome Assembly and Structural Characteristics Analysis of Gentiana rigescens

, an alpine plant with significant medicinal value, possesses a complex genetic background. However, comprehensive genomic research on is still lacking, particularly concerning its organelle genome. In this study, was studied to sequence the mitochondrial genome (mitogenome) and ascertain the assembly, informational content, and developmental expression of the mitogenome. The mitogenome of was 393,595 bp in length and comprised four circular chromosomes ranging in size from 6646 bp to 362,358 bp. The GC content was 43.73%. The mitogenome featured 30 distinct protein-coding genes, 26 tRNA genes, and 3 rRNA genes. The mitogenome of also revealed 70 SSRs, which were mostly tetra-nucleotides. In addition, 48 homologous fragments were found between the mitogenome and the chloroplast genome, with the longest measuring 23,330 bp. The documentation of the mitochondrial genome of is instrumental in advancing the understanding of its physiological development. Decoding the mitogenome will offer valuable genetic material for phylogenetic research on Gentianaceae and enhance the use of species germplasm resources.
