The leaves got right again: DNA phylogenetics supports a sister-group relationship between Eurystyles and Lankesterella (Orchidaceae: Spiranthinae)

Abstract: A pesar de notables similitudes en características no florales, tales como su desusado hábito epífito y su morfología vegetativa, Eurystyles y Lankesterella han sido considerados como sólo distantemente relacionados entre sí por los taxónomos que valoran los atributos florales por encima de cualquier otra fuente de información. En este trabajo evaluamos las relaciones filogenéticas de estos géneros analizando más de 4500 caracteres de secuencias de ADN nuclear (nrITS) y de plástidos (matK-trnK, trn… Show more

“…We performed cladistic analyses of sequence and indel data from two highly variable, non‐coding DNA regions: nuclear ribosomal ITS region (including the internal transcribed spacers, ITS1 and ITS2, and the intervening 5.8S gene; Baldwin et al ., 1995) and plastid trnL/trnF region (encompassing the intron of trnL , the intergenic spacer between trnL and trnF and partial exon portions; Taberlet et al ., 1991). Both these regions have succeeded, alone or in combination with one another or with other DNA regions, in resolving intra‐ and intergeneric phylogenetic relationships in Spiranthinae (Salazar et al ., 2003; Górniak et al ., 2006; Figueroa et al ., 2008; Salazar & Ballesteros‐Barrera, 2010; Batista et al ., 2011; Salazar & Dressler, in press) and other orchidoid lineages (e.g. Bellstedt, Linder & Harley, 2001; Kores et al ., 2001; Clements et al ., 2002; Bateman et al ., 2003; van der Niet et al ., 2005; Álvarez‐Molina & Cameron, 2009; Salazar et al ., 2009).…”

“…The vegetative morphology and anatomy have proved to be great data sources to the understanding of relationships in groups within Orchidaceae, as opposed to reproductive characters, notably prone to selective pressures by pollinator groups and therefore considered more homoplastic (Cameron 2005, Salazar & Dressler 2011. Previously, leaf anatomy of Tropidia was only known from T. curculigoides Lindl., species distributed from the Himalaya to New Caledonia (Stern et al 1993).…”
