Horizontal Gene Transfer in H. glycines genome V1


An alien index (AI) analysis (1) identified horizontally transferred genes in the H. glycines genome V1 . The alien index is a ratio of BLAST similarity between metazoan and non-metazoan sequences.  While 1,678 genes had alien indices greater than zero, only 151 had strong support (>30)(2).
