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:
Monocot
Estimated genome size:
Size:
1 m in height
Distribution:
Pearson's Aloe is highly localised, occurring in the north-western corner of South Africa and the southern parts of Namibia in the Lüderitz district. It has a narrow distribution that is limited to the area between Kuboes in the South African Richtersveld National Park and the mining town of Rosh Pinah in southern Namibia. Its distribution falls within, and contributes to the biodiversity of, the Gariep Centre of Plant Endemism.

Importance:
Rising temperatures and prolonged drought in the Richtersveld (2015–2020) caused major die-offs of Pearson's Aloe, which has very low recruitment and grows extremely slowly. Overgrazing has intensified the decline, as livestock and wildlife now feed on this species due to the scarcity of other plants. Although valued medicinally and horticulturally, it remains difficult to cultivate.
