E. urophylla × E. grandis high-quality genome and comparative genomics provide insights on evolution and diversification of eucalyptus.

ABSTRACT:

Background

Eucalyptus urophylla × Eucalyptus grandis, an economically important forest tree, provides important raw material for energy and reduces damage to native forests. However, the absence of a high-quality E. urophylla × E. grandis reference genome has significantly hindered its evolution and genetic analysis.

Results

We successfully presented a high-quality reference genome of E. urophylla × E. grandis (545.75 Mb; scaffold N50, 51.62 Mb) using a combination of the Illumina, PacBio HiFi, and Hi-C sequencing platforms. A total of 34,502 genes and 58.56% of the repetitive sequences in this genome were annotated. Using genome evolution analyses, we identified a recent whole-genome duplication (WGD) event in E. urophylla × E. grandis. We further found that gene families a
