Estimated genome size:
1.5 m in height
Size:
1.5 m in height
Distribution:
Brunia noduliflora occurs from the Cederberg southwards to the Cape Peninsula and eastwards as far as the Cockscomb in the Groot Winterhoek Mountains of the Eastern Cape, at altitudes from near sea level to approximately 1 500 m.
PromethION Sequencing Report:
Output:
39.88 Gigabases
Approximate N50:
16.91 kilobases
Draft Genome Assembly Statistics:
Genome Length:
0.72 Gigabases
BUSCO completeness score (single and duplicated genes):
97.40% [S: 47.0%, D: 50.0%]
Importance:
Brunia noduliflora is the most widespread species in the subgenus Brunia and occurs across diverse fynbos habitats in the Cape Floristic Region. Its broad ecological range makes it valuable for studying diversification and adaptation within the Bruniaceae.
Group:
Eudicot
Estimated genome size:
Size:
10m
Distribution:
The Giant Quiver Tree is confined to the northwestern part of South Africa and southern part of Namibia. There are three subpopulations, one that occurs in Namibia around Rosh Pinah, a second from the central Richtersveld area, and a third around Eksteenfontein in the southern parts of the Richtersveld. Most of the individuals occur within the AiAis/Richtersveld Transfrontier Park.

Importance:
These plants are valued for their age, resilience, and strong association with the Richtersveld, and are highly sought after for their architectural form, increasing their trade value in arid regions. Populations are declining due to illegal collection, mining-related habitat loss and degradation, and growing human pressure. Prolonged droughts, likely intensified by climate change, have caused mortality and increased baboon predation, posing major ongoing threats.
