Evolutionary relationships and taxonomy of Microtea (Microteaceae), a basal lineage in the core Caryophyllales.

ABSTRACT: The basal position of the small American genus Microtea within the core Caryophyllales was suggested only recently in accordance with molecular phylogeny. However, the specific relationships within the genus were not traced. The results of our phylogenetic analysis based on the matK chloroplast gene suggest the monophyly of Microtea, and Ancistrocarpus and other related genera should be included in it. Microtea is divided into two major sister clades: clade A consisting of M.glochidiata, M.maypurensis and M.tenuifolia, and clade B comprising M.debilis, M.sulcicaulis, M.scabrida, M.celosioides, and M.papillosa. The nrDNA dataset (ITS), although containing only a limited number of accessions, shows the same s
