Germacrene D, a common sesquiterpene in the genus Bursera (Burseraceae).
The volatile components of the leaves of five Bursera species, B. copallifera, B. exselsa, B. mirandae, B. ruticola and B. fagaroides var. purpusii were determined by gas chromatography-mass spectrometry (GC-MS). Germacrene D was one of the predominant components (15.1-56.2%) of all of these species. Germacrene D has also been found in other Bursera species and some species of Commiphora, the s...
متن کاملEvolution of Mexican Bursera (Burseraceae) inferred from ITS, ETS, and 5S nuclear ribosomal DNA sequences.
I reconstructed a phylogeny of 66 species and varieties of Bursera and 9 outgroup species using sequences of the internal transcribed spacer region (ITS), the 5S non-transcribed region (5S-NTS), and the external transcribed region (ETS) of nuclear ribosomal DNA. This study extends a previously proposed parsimony-based phylogenetic study that used the ITS sequences of 57 Bursera species and five...
متن کاملNuclear ribosomal DNA phylogeny and its implications for evolutionary trends in Mexican Bursera (Burseraceae).
The genus Bursera (Burseraceae) is one of the most diversified and abundant groups of plants of the tropical dry forests of Mexico. In order to provide a basis for better understanding of its evolutionary biology, we reconstructed a phylogeny of 57 species and varieties using the nucleotide sequences of the internal transcribed spacer regions (ITS1 and ITS2) of 18S-26S and the 5.8S coding regio...
متن کاملAn expanded nuclear phylogenomic PCR toolkit for Sapindales1
PREMISE OF THE STUDY We tested PCR amplification of 91 low-copy nuclear gene loci in taxa from Sapindales using primers developed for Bursera simaruba (Burseraceae). METHODS AND RESULTS Cross-amplification of these markers among 10 taxa tested was related to their phylogenetic distance from B. simaruba. On average, each Sapindalean taxon yielded product for 53 gene regions (range: 16-90). Ara...
متن کاملNota Di Lavoro 117 . 2010
We consider a multimarket framework where a set of firms compete on two interrelated oligopolistic markets. Prior to competing in these markets, firms can spy on others in order to increase the quality of their product. We characterize the equilibrium espionage networks and networks that maximize social welfare under the most interesting scenario of diseconomies of scope. We find that in some s...
