Abstract

The 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.

Keywords: Heuchera micrantha; Saxifragaceae; phylogeny; plastome.
