Abstract

We present a genome assembly of Hypericum pulchrum (slender St John's-wort; Streptophyta; Magnoliopsida; Malpighiales; Hypericaceae). The assembly consists of two haplotypes with total lengths of 373.14 megabases and 367.88 megabases. Most of haplotype 1 (94.8%) is scaffolded into 9 chromosomal pseudomolecules. Haplotype 2 was assembled to scaffold level. The mitochondrial sequences have lengths of 217.84 and 276.52 kilobases and the plastid genome assembly has a length of 149.16 kilobases. Gene annotation of this assembly on Ensembl identified 29 497 protein-coding genes. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.
