Abstract: Phylogenomics is a new phylogenetic field that aims to rebuild phylogenetic relationship of organisms using whole genome data. It can effectively eliminate the impact of horizontal gene transfer and variant evolutionary rates on phylogeny. According to the genome data type they are based on, these methods can be classified into five groups: multi-gene based, gene content based, gene order based, K-string based, and metabolic pathway based. The mechanism, speed, accuracy, applicable range and their application of these methods are summarized. The prospects of phylogenomics and challenges that it is faced with are also discussed.

Key words: phylogeny, phylogenetic tree, phylogenomics, gene content, K-string
