DIVERSIDAD GENÉTICA Y MEJORAMIENTO DE PLANTAS MEDICINALES= Medicinal plants and improvement of medicinal herbs:

Phylogenetic relationships among genera of the tribe Malveae (Malvaceae, subfamily Malvoideae) were reconstructed using sequences of the internal transcribed spacer (ITS) region of the 18S-26S nuclear ribosomal repeat.  Newly generated sequences were combined with those available from previous generic level studies to assess the current circumscription of the tribe, monophyly of some of the larger genera, and character evolution within the tribe.  The ITS data do not support monophyly of most generic alliances as presently defined, nor do the data support monophyly of several Malveae genera.  Two main well-supported clades were recovered, which correspond primarily to taxa that either possess or lack involucral bracts, resp.  Chromosomal evolution has been dynamic in the tribe with haploid nos. varying from n = 5 to 36.  Aneuploid redn., hybridization, and/or polyploidization have been important evolutionary processes in this group.
