Estimated genome size:

Up to 18 m tall

Size:

Up to 18 m tall

Distribution:

The species is native to large parts of sub-Saharan Africa (including, but not limited to South Africa, Namibia, Botswana, Zimbabwe). In South Africa, it is found in Limpopo, Mpumalanga, KwaZulu Natal, North West and some parts of Northern and Eastern Cape.

Genome Length:

0.39 Gigabases

BUSCO completeness score (single and duplicated genes):

98.8% [S: 97.4%, D: 1.4%]

Importance:

Sclerocarya birrea is an economically and culturally important African tree, valued for products such as Amarula Cream Liqueur, cosmetic oil, and its traditional medicinal uses, while also supporting rural livelihoods. Its drought tolerant and deep rooting system make it important in agroforestry and ecosystem resilience. Sequencing its genome will improve understanding of its biology, support conservation and breeding efforts, and enhance sustainable commercial development.

Psammobates tentorius tentorius

Karoo tent tortoise

Species Card Details

Importance:

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