Group:
Eudicot
Estimated genome size:
1.5 m
Size:
1.5 m
Distribution:
Maiden's Quiver Tree is restricted to desert mountainsides and arid ravines in South Africa (Richtersveld of the Northern Cape) and southern Namibia. Its distribution is concentrated within the Ai-Ais Richtersveld Transfrontier Park.
PromethION Sequencing Report:
Output:
379.51 Gigabases
Approximate N50:
12.36 kilobases
Draft Genome Assembly Statistics:
Genome Length:
11.21 Gigabases
BUSCO completeness score (single and duplicated genes):
99.9% [S: 92.7%, D: 6.8%]
Importance:
Aloidendron ramosissimum is threatened by plant theft, overgrazing, and ongoing habitat degradation. Its slow growth and low resilience mean disturbances, drought, and increased grazing pressure have long-term impacts, especially on juvenile survival. Climate change and possible mining activities are expected to further reduce its suitable habitat.

Genome size:
1 480 million DNA base pairs (1.48 Gigabases)
Size:
1.8 – 2 meters in height
Distribution:
Native to southern Africa, gannabos is found in South Africa, Botswana, and Namibia, and it is abundant in the Karoo, Little Karoo, and Eastern Cape areas. Thriving in dry watercourses of the hot and arid inland parts of southern Africa in areas where underground water is likely to be retained longest. Also growing on riverbanks and floodplains in loamy and saline soils which are dry for extended periods.

Importance:
Gannabos was used in the past by farmers to make lye and soap. It is heavily browsed by all types of wild and domestic animals, including ruminants and ostriches and is a valuable feed in times of scarcity. It is also one of the bushes that is part of a sheep's diet and is considered necessary for producing karoo lamb when selling meat.
