Characterization of the complete mitochondrial genome of yellow stripe mutant in onion (Allium cepa L.)

Abstract

The complete onion of yellow stripe mutant tissues mitochondrial genome was determined and analyzed in this study. The complete sequence length is 324,182 bp, including 37 CDS, 13 tRNA, and G + C content percentage of 45. Compared with the normal onions, 556 SNPs, 279 small indel numbers were detected, and the mutations of 14 SNPs and two small indels in the exon region affected the translation of proteins. Phylogenetic tree analysis showed that yellow stripe mutant onion is closely clustered with other Allium cepa L. The mutant of onion plays an important role in developing molecular marker-assisted breeding.
