  abstract = {{T}he flowering plant family {A}nnonaceae includes important commercially grown tropical crops, but development of promising species is hindered by a lack of genomic resources to build breeding programs. {A}nnonaceae are part of the magnoliids, an ancient lineage of angiosperms for which evolutionary relationships with other major clades remain unclear. {T}o provide resources to breeders and evolutionary researchers, we report a chromosome-level genome assembly of the soursop ({A}nnona muricata). {W}e assembled the genome using 444.32 {G}b of {DNA} sequences (676x sequencing depth) from {P}ac{B}io and {I}llumina short-reads, in combination with 10x {G}enomics and {B}ionano data (v1). {A} total of 949 scaffolds were assembled to a final size of 656.77 {M}b, with a scaffold {N}50 of 3.43 {M}b (v1), and then further improved to seven pseudo-chromosomes using {H}i-{C} sequencing data (v2; scaffold {N}50: 93.2 {M}b, total size in chromosomes: 639.6 {M}b). {H}eterozygosity was very low (0.06%), while repeat sequences accounted for 54.87% of the genome, and 23,375 protein-coding genes with an average of 4.79 exons per gene were annotated using de novo, {RNA}-seq and homology-based approaches. {R}econstruction of the historical population size showed a slow continuous contraction, probably related to {C}enozoic climate changes. {T}he soursop is the first genome assembled in {A}nnonaceae, supporting further studies of floral evolution in magnoliids, providing an essential resource for delineating relationships of ancient angiosperm lineages. {B}oth genome-assisted improvement and conservation efforts will be strengthened by the availability of the soursop genome. {A}s a community resource, this assembly will further strengthen the role of {A}nnonaceae as model species for research on the ecology, evolution and domestication potential of tropical species in pomology and agroforestry.},
