M. author Marum, Liliana author Carolina Varela, Maria author Matos, José author Simões, Fernanda author Miguel, Célia author Oliveira, Margarida author Ricardo, Cândido author Gonçalves, Sónia author Marcos Ramos, António author Ricardo, Cândido author 2023-11 Cork oak (Quercus suber L.) is an ecologically and economically important evergreen tree species native to the Mediterranean region and widespread in southwest Europe and northwest Africa. An improved genome assembly of cork oak using a combination of Illumina and PacBio sequencing is presented in this study. The assembled genome contains 2351 scaffolds longer than 1000 bp, accounting for 765.7 Mbp of genome size, L90 of 755, and a N50 of 1.0 Mbp, with 40,131 annotated genes. The repetitive sequences constitute 53.6% of the genome. The genome sequences of chloroplast and mitochondrion were determined for the first time, with a genome size of 161,179 bp and 531,858 bp, respectively. Phylogenetic analysis based on complete chloroplast genome sequence showed that Q. suber is closely related to Quercus variabilis, two corkproducing species with commercial use. All data generated are available through the public databases, being ready to be used without restrictions. This study provides an improved nuclear genome assembly together with the organelle genomes of cork oak. These resources will be useful for further breeding strategies and conservation programs and for comparative genomic studies in oak species. http://hdl.handle.net/10459.1/469064 Cork oak Genome assembly Genome annotation Mitochondrial genome Phylogenetic analysis An improved reference genome and first organelle genomes of Quercus suber
