Molecular phylogeny of two Amelanchier (Rosaceae) species based on plastid DNA sequences

Amelanchier is a taxonomically complex genus because of its reproductive biology and variation in morphological characters. In Türkiye, two Old World Amelanchier species, A. ovalis and A. parviflora, occur with intraspecific taxa recognized at the subspecies and varietal levels, respectively. To assess phylogenetic relationships, we investigated seven Amelanchier species covering different geographic ranges and reconstructed phylogenetic trees using rpl20–rps12, psbA–trnH, and trnH– rpl2 markers. For this study, more than 30 sequences representing A. ovalis and A. parviflora were newly generated. Phylogenies were constructed using Maximum Likelihood and Bayesian inference. Our findings support a biogeographic disjunction among Amelanchier taxa rather than clearly resolved species-level phylogenetic relationships.
