Found in grassland habitats across Southern Africa.
PromethION Sequencing Report:
Output:
122.04 Gigabases
Approximate N50:
9.24 kilobases
Draft Genome Assembly Statistics:
Genome Length:
2.75 Gigabases
BUSCO completeness score (single and duplicated genes):
99.6% [S: 60.8%, D: 38.8%]
Importance:
Some populations of this species in the Barberton region of South Africa have evolved the ability to hyperaccumulate nickel, making this species ideal for a comparative genomics approach to understand the evolution of this extreme phenotype.
Group:
Eudicot
Genome size:
700 million DNA base pairs (0.7 Gigabases)
Size:
2.2 – 4 meters in height
Distribution:
The Karoo num-num occurs in wooded areas, extending from the southwestern Western Cape along the coast through the Eastern Cape, KwaZulu-Natal, into the Free State, Gauteng, and the northern provinces. Its range also includes Lesotho, Eswatini, Zimbabwe, Mozambique, Botswana, and Namibia, with sporadic occurrences as far north as Kenya. Its leaves and thorns exhibit marked variation across its distribution.

Karoo num-num

Importance:
Karoo num-nums are evergreen and provide food and shelter for a wide range of wildlife. They are wind resistant and moderately drought-tolerant, but susceptible to frost. They are cultivated for ornamental use as shrubs and hedges with starry white flowers and bright red edible fruit. The roots have been used medicinally to treat toothache. The num-num is also used in traditional Swazi ceremonies.
