Abstract
The complete plastid genome of Scutellaria microviolacea C. Y. Wu was firstly reported. The full length of the plastid genome was 152,092 bp and comprised of a large single-copy (LSC) region of 84,090 bp, a small single-copy (SSC) region of 17,534 bp, and two inverted repeat regions (IRs) of 25,234 bp. A total of 131 genes were encoded, including 87 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. The overall GC content of the S. microviolacea plastid genome was 38.3%. Further phylogenetic analysis based on 18 accessions inferred that the genus Scutellaria can be divided into two clades, and S. microviolacea is evolutionarily close to Scutellaria tsinyunensis. Our study provided essential genetic resources for further studies on the evolution and genetic diversity of the genus Scutellaria and its related taxa.
