Abstract

In this study, we aimed to determine the complete nucleotide sequences of the chloroplast genomes of Medicago sativa L. and Medicago falcata L. and perform their phylogenomic analysis. The chloroplast genomes of M. Sativa and M. falcata were found to be 125,095 and 125,810 bp in length, respectively. Additionally, the AT contents of M. Sativa and M. falcata are 66.1% and 66.2%, respectively. Each chloroplast genome contained the same 109 unique genes, including 29 transfer RNA genes, 4 ribosomal RNA genes, and 76 protein-coding genes. Phylogenomic analysis based on complete chloroplast genomes from the Medicago showed that the geographical environment has no significant effect on their genomic composition.

Keywords: Medicago; chloroplast genome; phylogenomic analysis.
