<b>High-quality haplotype-resolved genome assembly for ring-cup oak</b><b><i> </i></b><b>(</b><b><i>Quercus glauca</i></b><b>) provides insight into oaks demographic dynamics</b>

<i>Quercus</i> section <i>Cyclobalanopsis</i> represents a dominant woody lineage in East Asian evergreen broadleaved forests. Regardless of its ecological and economic importance, little is known about the genomes of species in this unique oak lineage. <i>Quercus glauca </i>is one of the most widespread tree species in the section <i>Cyclobalanopsis</i>. In this study, a high-quality haplotype-resolved reference genome was assembled for <i>Q. glauca</i> from PacBio HiFi and Hi-C reads. The genome size, contig N50, and scaffold N50 measured 902.88 Mb, 7.60 Mb, and 69.28 Mb, respectively, for haplotype1, and 913.28 Mb, 7.20 Mb, and 71.53 Mb, respectively, for haplotype2. The LTR Assembly Index of the <i>Q. glauca</i> genome was greater than 22. A total of 37,457 and 38,311 protein-coding genes were predicted in haplotype1 and haplotype2, respectively.
