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.

Size:
0.5 – 1 meter in height
Distribution:
Lessertia frutescens occurs naturally throughout the dry parts of southern Africa – in Western Cape and up the west coast as far north as Namibia and into Botswana, and in the western Karoo to Eastern Cape. It is also found in KwaZulu-Natal and Mpumalanga. It shows remarkable variation within its distribution

Lessertia frutescens
Cancer bush
Importance:
This plant is one of the most discussed in the ethnobotanical world because it has a strong reputation as a cure for cancer and increasingly as an immune booster in the treatment of HIV/AIDS. It has long been known, used and respected as a medicinal plant in southern Africa. There is preliminary clinical evidence that it has a direct anti-cancer effect in some cancers and that it acts as an immune stimulant. Research on its properties is ongoing.
