Abstract

We present a chromosome-level, haplotype-resolved genome assembly from Greenland scurvy-grass (Cochlearia groenlandica). The assembly comprises two pseudo-haplotypes of 322 Mb and 295 Mb, with 89.7% and 95.6% respectively, each scaffolded into 7 chromosomes. Assembly completeness is high (BUSCO 97.8% in each haplotype), with 34,213 and 29,684 annotated protein-coding genes for haplotypes one and two, respectively. The chromosomes contain extensive centromeric satellite arrays that cover up to half of some chromosomes. Their precise functional boundaries remain undetermined.
