phylogenetic relationships within the lythraceae in iran

The lythraceae consists of a group of plants with a complex taxonomy. the difficulty of classifying them becomes particularly clear when morphological characteristics are used. in the flora iranica and the flora of iran, this family is represented by five and four genera, respectively. in the present study, three genera lythrum, ammannia, and rotala, and six species of lythraceae growing in iran were analyzed, using nine cpdna trnh-psba and 21 nrdna its sequences retrieved from genbank. phylogenetic relationships within the family were evaluated based on cpdna trnh-psba and nrdna its, as well as combined datasets using maximum parsimony, maximum likelihood, and bayesian inference methods. most of the reconstructed trees revealed the monophyly of the above-mentioned genera in iran. all trees confirmed the distinctiveness of species within these three genera. the results of this study indicate a phylogenetic alliance of l. thesioides with l. silenoides and the three species l. thymifolia, l. junceum and l. hyssopifolia. moreover, a. coccinea is evolutionarily related to a. multiflora and a. baccifera to a. auriculata. the results indicate that, a taxonomic revision of these genera is required. in addition, the evolutionary patterns of some diagnostic morphological and micromorphological characters were evaluated in this study.
