Acacia species are found at various arid and semiarid regions. Among the tree genera of family,Fabaceae, Acacia contains the highest number of species. We have collected different species ofAcacia from various places of Saudi Arabia and reconstructed phylogeny for evaluation of geneticrelationship among them. Internal transcribed spacer sequence of nrDNA nrDNA-ITS locus wasused for the reconstruction of phylogeny among these species. Based on phylogenetic tree, Acaciaetbaica and A. johnwoodii were close to each other. Similarly, A. ehrenbergiana and A. tortilis wereclose to each other. Thus, this gene locus was helpful in evaluating the genetic relationship amongthese species.
