Group:

Eudicot

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:

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.

Microhodotermes viator

Southern harvester termite

Species Card Details

Importance:

The Southern harvester termite is ecologically important in South African arid and semiarid ecosystems, particularly the Succulent Karoo and Nama Karoo biomes. It is a dominant decomposer and primary soil engineer, breaking down dry plant material and contributing to nutrient cycling, soil structure, and water infiltration. This termite’s genome sequence is important because it can: ① Reveal genetic adaptations to arid environments and extreme temperature fluctuations; ②. Shed light on the early evolution of termites; ③ Fill a major gap in termite phylogenomics, improving our understanding of termite diversification; ④ Inform conservation and land management in fragile dryland ecosystems facing climate change.
