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.

Psammobates tentorius verroxii
Bushmanland tent tortoise

Importance:
The Bushmanland tent tortoise, an important seed disperser for various plant species and endemic to South Africa and Namibia, is arguably one of the most taxonomically confusing and morphologically polymorphic species of Testudines. It is listed as "Near Threatened" by the IUCN and occurs in the Upper Karoo, Bushmanland regions of South Africa, and southern Namibia. It only occurs in the Nama Karoo Biome. Remarkably, no genomic studies have been conducted on any tortoise species in Africa or across the entire Southern Hemisphere.
