The complete plastome sequence of Heuchera micrantha Douglas ex Lindl. (Saxifragaceae), an ornamental plant

Abstract

AbstractThe perennial herb Heuchera micrantha (Saxifragaceae) is a popular ornamental plant. However, the plastome sequence of H. micrantha has not been reported yet. Here, we assembled the complete plastome of H. micrantha using Illumina high-throughput pair-end sequencing. The plastome is a circular DNA molecule of 155,469 bp, comprising a pair of inverted repeat (IR, 25,654 bp) regions, a small single copy (SSC, 18,050 bp) region, and a large single copy (LSC, 86,111 bp) region. It encodes 129 genes, of which 84 are protein-coding genes, 37 are transfer RNAs, and eight are rRNAs. The total GC content is 37.8%. Phylogenetic analysis shows that H. micrantha, together with three other Heuchera species is clustered with Tiarella cordifolia. This complete plastome is beneficial for future genetic research on the Heuchera group.
