Flye

Genome Length:

0.66 Gigabases

BUSCO completeness score (single and duplicated genes):

98.1% [S: 37.6%, D: 60.5%]

BUSCO database:

viridiplantae

Importance:

This indigenous tree species is important due to its resistance to the polyphagous shot hole borer (PSHB), as recognised in the 2023 FABI replant list. Sequencing its genome could reveal the mechanisms underlying this resistance, inform conservation strategies, and contribute to understanding PSHB risk to South African tree biodiversity.
