Group:
Reptile
Estimated genome size:
10 - 20 cm (total body length)
Size:
10 - 20 cm (total body length)
Distribution:
Endemic to the Republic of South Africa, occurring in Little Namaqualand from Port Nolloth to Clanwilliam.
PromethION Sequencing Report:
Output:
48.66 Gigabases
Approximate N50:
5.93 kilobases
Draft Genome Assembly Statistics:
Genome Length:
1.56 Gigabases
BUSCO completeness score (single and duplicated genes):
98.8% [S: 96.9%, D: 2.0%]
Importance:
It serves as an important model species for studying specific stages of limb development within the genus Scelotes, representing an intermediate limb development stage (forelimb digits = 0; hindlimb digits = 2), and for investigating the genomic evolution of vertebrates. It has a restricted distribution and occurs in distinct habitats and regions, making it an excellent model species for biogeographic and molecular ecology studies.

Portulacaria afra
Spekboom

Importance:
Spekboom is known for its carbon sequestration, adaptability to harsh environments and soil binding properties that can help prevent erosion. It has low water requirements and edible leaves that are high in Vitamin C, enjoyed by wild animals (especially elephants) and humans alike.
