Phylogenetic study some of Crataegus L. (Rosaceae, Pyreae) Species in Iran
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 11
Abstract
Crataegus belongs to Pyreae tribe and Rosaceae family. Crataegus, has about 700 species, distributed mainly in temperate regions of northern Hemisphere. Diagnoses of these species rely on morphological features of leaves, flowers and fruits. We used nuclear (ribosomal ITS) DNA regions to estimate the phylogeny of Crataegus species of Iran. Maximum parsimony, maximum likelihood, and Bayesian analyses all corroborate the sister group relationship between Crataegus and Mespilus, and Crataegus brachyacantha is sister to the rest of that genus species. According to results, Mespilus is considered as sister group to the monophyletic Crataegus species. Trees are divided into two main brands which show separation of old world from new world species. Accordingly, we (1) suggest the separation of Pentagynae section from Crataegus section (2)recommend the presence of a new subspecies of C. pentagyna from Iran ; (3)relate that C. persica is the synonym of C. meyeri and also C. aminii is the synonym of C. atrosanguinea (4)report the appearance of C. rhipidophylla in North-West of Iran and (5)suggestion of change ranking of C. zarreii as variety of C. azarolus.
