Abstract: With the rapid development of sequencing technology and bioinformatic analysis tools, the studies of plant genomes has been growing in an unprecedent speed. The family Lauraceae belongs to Magnoliids and is mainly found in pantropics with high species diversity. Species of this family are mostly woody and economically and ecologically important. Up to now, 13 genomes belonging to 8 species in the family Lauraceae have been published. Here, we review the recent advances on the published nuclear genomes of Lauraceae by focusing on their characteristics, evolution and phylogeny, and the functional genes and gene families. We highlight the recent achievements in the whole genome duplication events, and the genes/gene families related to the floral organ determination and metabolites in Lauraceae. Finally, we suggest further studies should be performed to improve our understanding of the function and evolution of this family by sequencing more species as well as more representative samples in all major clades, especially by tackling species with special value, and studying the species-specific functional genes.

Key words: Lauraceae, evolution, nuclear genome, function gene, phylogeny
