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.

Importance:
The dwarf cushion star is a widespread and ecologically significant intertidal species in South Africa. It contributes to biodiversity by maintaining balance in rocky shore ecosystems and serving as prey and grazer. Sequencing its genome will provide insights into adaptation to harsh intertidal conditions, population connectivity, and resilience to environmental change, supporting conservation and enhancing understanding of echinoderm evolution within South Africa's unique marine biodiversity.
