Eastern Cape in the area near Gqeberha and Kariega.

PromethION Sequencing Report:

Output:

29.49 Gigabases

Approximate N50:

4.85 kilobases

Assembly N50:

21 039 kilobases

Contig number:

507

Draft Genome Assembly Statistics:

Assembler used:

Hifiasm

Genome Length:

0.28 Gigabases

BUSCO completeness score (single and duplicated genes):

99.6% [S: 99.0%, D: 0.6%]

BUSCO database:

insecta

Importance:

Porthetes beetles are pollinators of Encephalartos cycads. Both the cycads and weevils have a high extinction risk. Genome sequencing provides a basis for further molecular studies to understand host specificity and options for conserving and recovering pollinator interactions.
