Chromosome-scale, haplotype-resolved genome assembly of Suaeda glauca

<p><em>Suaeda glauca</em>is an annual herb of Suaeda and an important saline-alkali plant resource, which is widespread on beaches and saline lands around the world. It is also a good candidate for food, feed, and drug development. There has been no publication of the&nbsp;<em>Suaeda glauca</em>genome assembly, limiting the evolutionary study of Amaranthaceae and the bioavailability of&nbsp;<em>Suaeda glauca</em>.</p> <p>Using PacBio HiFi and Hi-C sequencing data, we successfully generated chromosome-scale, haplotype-resolved assemblies of the&nbsp;<em>Suaeda glauca</em>genome. The size of the final primary assembly was 622.95 Mb, and the contig N50 was 19.42 Mb, which was successfully anchored to 9 chromosomes, accounting for 96.79% of the total assembly size. The repeat content and genome size of&nbsp;<em>Suaeda glauca</em>are much higher than those of the same genus&nbsp;<em>Suaeda aralocaspica</em>, presumably due to a recent burst of LTR insertions. Using HiFi reads, we assembled the complete circular chloroplast genome of&nbsp;<em>Suaeda glauca</em>. Through gene family and phylogenetic tree analysis, it was shown that&nbsp;<em>Suaeda glauca</em>and&nbsp;<em>Suaeda aralocaspica</em>differentiated at ~26.36 million years ago (MYA), and Amaranthaceae species began to differentiate at ~52.00 MYA.</p>
