Annona muricata Genome sequencing and assembly. Annona muricata

The genus Annona belongs to the family Annonaceae, which resides within the magnoliids, plays a crucial role in revealing the evolution of magnolias, and is an important fruit resource. Here, we report a chromosome-level genome assembly of A. montana, an edible and ornamental fruit species of Annona. Integration with other genomes provides clear evidence that the magnoliids were sisters to eudicots, and the ASTRAL trees showed discordance in the phylogenetic position of magnoliids, which might cause by incomplete lineage sorting (ILS). The whole genome duplication (WGD) analysis showed that the common ancestor of A. montana and Liriodendron chinense experienced a WGD event, and this WGD event occurred after the split of Magnoliales and Laurales.
