Abstrakt:	Syzygium is a large and diverse tree genus in the Myrtaceae family. Genome assemblies for clove ( Syzygium aromaticum , 370 Mb) and sea apple ( Syzygium grande , 405 Mb) provided the first insights into the genomic features and evolution of the Syzygium genus. Here, we present additional de novo chromosome-scale genome assemblies for Syzygium malaccense, Syzygium aqueum, Syzygium jambos , and Syzygium syzygioides. Genome profiling analyses show that S. malaccense , like S. aromaticum and S. grande , is diploid (2n = 2x = 22), while the S. aqueum , S. jambos , and S. syzygioides specimens are autotetraploid (2n = 4x = 44). The genome assemblies of S. malaccense (430 Mb), S. aqueum (392 Mb), S. jambos (426 Mb), and S. syzygioides (431 Mb) are highly complete (BUSCO scores of 98%). Comparative genomics analyses showed conserved organization of the 11 chromosomes with S. aromaticum and S. grande , and revealed species-specific evolutionary dynamics of the long terminal repeat retrotransposon elements belonging to the Gypsy and Copia lineages. This set of Syzygium genomes is a valuable resource for future structural and functional comparative genomic studies on Myrtaceae species.
