Group:
Eudicot
Estimated genome size:
15 – 30 cm in height
Size:
15 – 30 cm in height
Distribution:
Sceletium (Mesembryanthemum) tortuosum occurs in the Succulent Karoo and Namaqualand Karoo regions of the Cape provinces of South Africa, primarily in semi-arid environments.
PromethION Sequencing Report:
Output:
63.19 Gigabases
Approximate N50:
6.65 kilobases
Draft Genome Assembly Statistics:
Genome Length:
0.76 Gigabases
BUSCO completeness score (single and duplicated genes):
96.8% [S: 89.7%, D: 7.2%]
Importance:
Sceletium (Mesembryanthemum) tortuosum has a long history of traditional use for relieving thirst, hunger and fatigue, as well as for social and spiritual purposes. A reference genome will help researchers understand the genetic basis of mesembrine alkaloid production and support conservation of wild populations.
Group:
Eudicot
Estimated genome size:
Size:

Distribution:
Northern Cape and Western
Cape, Calvinia to
Malmesbury.
PromethION Sequencing Report:
Output:
42.48 Gigabases
Approximate N50:
11.22 kilobases
Assembly N50:
23 851.55 kilobases
Contig number:
2 130
Draft Genome Assembly Statistics:
Assembler used:
Hifiasm
Genome Length:
0.81 Gigabases
BUSCO completeness score (single and duplicated genes):
97.0% [S: 93.6%, D: 3.4%]
BUSCO database:
viridiplantae
Importance:
Mesembryanthemum expansum is a South African endemic, medicinally recognised succulent of the Succulent Karoo whose understudied wild populations, combined with a complete absence of cytogenetic or genomic data, make it a highly valuable candidate for foundational genetic, ecological, and conservation research into southern-African mesemb biodiversity.
