We present a genome assembly of Euonymus europaeus (spindle; Streptophyta; Magnoliopsida; Celastrales; Celastraceae). The genome sequence has a total length of 441.88 megabases. Most of the assembly (99.61%) is scaffolded into 16 chromosomal pseudomolecules. The mitochondrial sequences have lengths of 913.22, 326.74 and 225.31 kilobases, and the plastid genome assembly has a length of 157.27 kilobases. Gene annotation of this assembly on Ensembl identified 19 856 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.
Christenhusz et al. (2026) studied this question.
