The complete chloroplast genome sequence of Gazania rigens and the phylogenomic analysis of Gazania species

Gazania rigens is a popular ornamental plant. This study deciphers its complete chloroplast genome. The genome is 150,688 bp in length and exhibits a typical circular quadripartite structure with a GC content of 37.54%. It encodes a total of 127 unique genes, including 79 protein-coding genes, 40 tRNA genes, and 8 rRNA genes. Phylogenetic analysis based on this genome elucidates the evolutionary relationships of G. rigens among closely related taxa. This sequence provides a foundational resource for future biotechnological applications in this ornamental species.
