Conferencia: "Phylogeny of Umbilicaria species -a combined approach using molecular and morphological data" por Beata Krzewicka.

Abstract: Umbilicaria Hoffm. is a well–known genus of umbilicate, foliose, lichen–forming fungi comprising c. 85 currently accepted species occurring almost exclusively on siliceous rocks in the polar, alpine and high–alpine biomes. Important morphological and anatomical characters used to separate the species in this genus are an apothecium morphology and type of asexual propagules. Molecular data provide additional characters useful to test the validity of the species circumscriptions.

During the SYNTHESYS project ES-TAF-1431 ITS nrDNA and LSU nrDNA sequences were used to examine relationships between closely related species of some European Umbilicaria. Based on morpholocial and molecular data, two new species were described: Umbilicaria iberica Sancho & Krzewicka and U. maculata Krzewicka, M. P. Martín & M. A. García.

The present study (SYNTHESYS project ES-TAF-1261) is a continuation of the last project and is focused on global diversity of Umbilicaria species as an effect of the climate changes. Sequence data of the ITS nrDNA and LSU nrDNA, RBP1, RBP2 and SSU mtDNA are exploring to use in phylogenetic analyses. 


Beata Krzewicka, visitante del Programa Synthesys en el Real Jardín Botánico, CSIC, ofrecerá el próximo viernes, 11 de junio, a las 13:00 horas, en la Sala de Seminarios , este seminario científico, que se realizará en idioma inglés.

La entrada es libre y gratuita (hasta completar el aforo). Los interesados deben acceder al Real Jardín Botánico, CSIC, por la puerta situada en la Cuesta de Claudio Moyano, 1.
