From genome to gene expression: the genomic landscape of a hybrid species of Eucalyptus urophylla × Eucalyptus grandis and its divergence from parental species hybrid.

ABSTRACT:

Background

Eucalyptus urophylla × Eucalyptus grandis (E. urograndis) is a globally significant forest tree species renowned for its rapid growth, high yield, and exceptional wood production efficiency. A comparative analysis of its parental genomes, coupled with an in-depth investigation of the expression patterns of wood-related genes, will provide critical genomic resources to enhance research and utilization of this superior eucalypt hybrid species.

Results

In this study, we present a draft genome assembly consisting of 592.09 Mb of data, with 99.91% anchored to 11 pseudochromosomes. The assembly achieved a contig N50 of up to 3.73 Mb and a scaffold N50 of up to 58.62 Mb. Gene annotation and evaluation revealed that the E. urograndis genome contains 32,151 genes, of which
