The phylogeny of Rosoideae (Rosaceae) in Iran, based on cpDNA and nrDNA sequenced data

The present survey deals with phylogenetic analyses of Rosoideae from Iran. A total of ۳۴ taxa from ۶ tribes and ۴ subtribes of Iranian taxa plus ۳۶ previously sequenced data were analyzed for trnL-F, rpl۳۲-trnL (UAG) PsbA-trnH and nrDNA ITS regions. For data analysis, both Maximum parsimony (as implemented in PAUP) and Bayesian method (using MrBayes program) was used. In all the reconstructed phylogenetic trees, the following clades are given phylogenetic definitions: Colurieae, Agrimonieae, Potentilleae and their subclades. The monophyly of Colurieae, Agrimonieae, Potentilleae were well documented.The current results support circumscriptions of the genera Geum, Agrimonia and Aremonia (presented in Flora of Iran). However, it displays divergence of the genus Sanguisorba in to two monophyletic groups ( a) Sanguisorba minor and three subspecies b) Sanguisorba officinalis group) and the union of the genera Fragaria, Alchemilla, Aphanes, Drymocallis, Sibbaldia and Sibbaldianthe within Fragariinae􀀃and Duchesnea, Ivesia , Horkelia and Argentina within Potentilleae. In this study, the evolutionary trend of exin sculpturing was discussed.
