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

Phylogenetic relationships within subfamily Bromelioideae (Bromeliaceae, Poales) were inferred using DNA sequence data from the low-copy nuclear gene phosphoribulokinase (PRK) and 5 plastid loci (matK gene, 3'trnK intron, trnL intron, trnL-trnF spacer, atpB-rbcL spacer).  The PRK dataset exhibited a considerably higher proportion of potentially informative characters than the plastid dataset (16.9% vs. 3.1%), leading to a higher resoln. and improved nodal support of the resulting phylogenies.  Bromelia is resolved as sister to the remainder of the subfamily, albeit this relationship receives only weak nodal support.  The basal position of Bromelia, as well as Deinacanthon, Greigia, Ochagavia, Fascicularia, and Fernseea within the subfamily is corroborated and the remainder of the subfamily forms a highly supported clade (the eu-bromelioids).  By the inclusion of nuclear data, the sister group position of Fernseea to the eu-bromelioids is now highly supported.  Within the eu-bromelioids, the resoln. of the clade representing the more advanced core bromelioids has increased and further demonstrates the highly problematic generic concept of Aechmea as well as Quesnelia.  Moreover, the data were used to examine the evolution of sepal symmetry and the tank habit.  Tracing of character transitions onto the mol. phylogeny implies that both characters have undergone only few transitions within the subfamily and thus are not as homoplasious as previously assumed.  The character state reconstruction reveals the great importance of the evolution of the tank habit for the diversification of the core bromelioids.
