Abstract
The genus Avicennia contains of 8 species which show a great extent of morphological and genetic variability, which make taxonomy of the genus difficult. Molecular barcoding along with advancement in computational approaches may be proper methods to investigate and assess the efficiency of different molecular genetic regions in Avicennia species delineation and also produce data on species evolution and divergence. The aims of present study were to utilize multiple genetic data for the species delineation and study the phylogeny of the genus. Moreover, we developed a hypothesis on biogeography of these species with respect to barcode divergence. The results showed that both Internal transcribed spacer (ITS) and trnHG–psbA intergenic spacer (trnHG-psbA) sequences may be used in Avicennia species delineation. Barcode gap analysis and nucleotide difference of the studied taxa showed significant Fst for pair-wise species comparison and the role of nucleotide changes in Avicennia speciation.
期刊介绍:
Caryologia is devoted to the publication of original papers, and occasionally of reviews, about plant, animal and human karyological, cytological, cytogenetic, embryological and ultrastructural studies. Articles about the structure, the organization and the biological events relating to DNA and chromatin organization in eukaryotic cells are considered. Caryologia has a strong tradition in plant and animal cytosystematics and in cytotoxicology. Bioinformatics articles may be considered, but only if they have an emphasis on the relationship between the nucleus and cytoplasm and/or the structural organization of the eukaryotic cell.
