Abstract

The complete chloroplast genome of Isatis minima, a typical ephemeral plant of Brassicaceae in the Central Asia desert, was sequenced and characterized in this study. The genome 153,642 bp in size, contains a typical quadripartite genome organization including LSC and SSC regions of 83,423 bp and 17,709 bp, and two copies of the IR regions of 26,255 bp. It has 113 unique genes, including 79 protein-coding, 30 tRNA, and four rRNA genes. Phylogenetic analysis fully resolved I. minima in a monophyletic clade with I. tinctoria. This bioinformatic data contributes to the phylogenetics systematics and evolutionary history of Brassicaceae.

Keywords: Brassicaceae; Isatis minima; chloroplast genome; ephemeral plants.
