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.
