We present a genome assembly of Lepidium didymum (Lesser Swine-cress; Streptophyta; Magnoliopsida; Brassicales; Brassicaceae). The genome sequence has a total length of 345.12 megabases. Most of the assembly (97.35%) is scaffolded into 16 chromosomal pseudomolecules. The mitochondrial sequence has a length of 262.68 kilobases and the plastid genome assembly has a length of 154.85 kilobases. Gene annotation of this assembly on Ensembl identified 38 202 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.
