Size:
0.3 meters in height.
Distribution:
Found in grassland habitats across Southern Africa.
PromethION Sequencing Report:
Output:
122.04 Gigabases
Approximate N50:
9.24 kilobases
Draft Genome Assembly Statistics:
Genome Length:
2.75 Gigabases
BUSCO completeness score (single and duplicated genes):
99.6% [S: 60.8%, D: 38.8%]
Importance:
Some populations of this species in the Barberton region of South Africa have evolved the ability to hyperaccumulate nickel, making this species ideal for a comparative genomics approach to understand the evolution of this extreme phenotype.
Group:
Eudicot
Estimated genome size:
Size:
0.15 m (height), rhizomatous and forms spreading mats

Importance:
The species is of global importance in horticulture and is a common, ecologically important coastal dune and rock pioneer species on the southern and eastern South African shoreline. Genomic information is vital for future breeding of ornamental Gazania cultivars and to unravel the taxonomy, cytology, evolution, genetic diversity and biogeography of Gazania.
