Mitochondrial DNA B Resour. 2025 Jan 12;10(2):103-107. doi: 10.1080/23802359.2024.2438290. eCollection 2025.

Abstract

Solanum melongena 'Yunqie 9' was selected by the Horticultural Research Institute of Yunnan Academy of Agricultural Sciences based on the local environment of Yunnan Province. It is excellent in fruit quality and yield, but it is relatively weak in disease resistance. No information on complete chloroplast genome and position in the phylogeny of Solanum to restrict its genetic improvement. In this study, the chloroplast genome of 'Yunqie 9' was sequenced using Illumina high-throughput sequencing technology. The size of the complete chloroplast genome was 155,579 bp in length with an GC content of 37.70%, composed of a large single-copy region (86,189 bp), a small single-copy region (18,504 bp), and a pair of inverted repeat regions (25,443 bp). A total of 134 coding genes were annotated in the entire chloroplast genome, including 89 protein-coding genes, 37 transfer RNA genes, and 8 ribosomal RNA genes. Phylogenetic analysis based on chloroplast genome sequences of 20 species in the Solanaceae family indicated that except for the cultivated Solanum, 'Yunqie 9' was closely related to Solanum melongena×Solanum torvum and Solanum insanum.

Keywords: Solanum melongena; chloroplast genome; phylogenetic analysis.
