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.

Serruria rosea
Rose spiderhead

Importance:
The Rose spiderhead is one of the most delicate members of the Proteaceae family. It is classified as Near Threatened, so does not currently qualify for any of the threat categories. Due to possible future threats from afforestation, invasive alien plants and susceptibility to drought it may become threatened. Serruria has grown into an important member of the indigenous floriculture industry of South Africa. It is also used in the pot plant industry due to its compact size.
