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.

Oxalis natans
Water Sorrel
.jpg)
Importance:
This highly threatened species is one of the true aquatic species in Oxalis, but much of its original habitat has been lost to urbanisation. Interestingly, it is completely unrelated to the other aquatic species - the genome of this species may offer insights into its conservation, and also into the convergent evolution of an aquatic habit in South African Oxalis. It is Redlisted as Critically Rare.
