ABSTRACT: 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 of
Acacia from various places of Saudi Arabia and reconstructed phylogeny for evaluation of genetic
relationship among them. Internal transcribed spacer sequence of nrDNA (nrDNA-ITS) locus was
used for the reconstruction of phylogeny among these species. Based on phylogenetic tree, Acacia
etbaica and A. johnwoodii were close to each other. Similarly, A. ehrenbergiana and A. tortilis were
close to each other. Thus, this gene locus was helpful in evaluating the genetic relationship among
these species.
