Premise Lantana and Lippia (Verbenaceae) are two large Linnean genera whose classification has been based on associated fruit traits: fleshy vs. dry fruits one seed-bearing units. We reconstruct evolutionary relationships the evolution of traits to test validity these for classification. Methods Previous studies plastid DNA sequences provided limited resolution this group. Consequently, seven n...

The products of the Rhizobium leguminosarum hyp gene cluster are necessary for synthesis of a functional uptake [NiFe] hydrogenase system in symbiosis with pea plants, and at least for HypB and HypF, a role in hydrogenase-specific nickel metabolism has been postulated (L. Rey, J. Murillo, Y. Hernando, E. Hidalgo, E. Cabrera, J. Imperial, and T. Ruiz-Argüeso, Mol. Microbiol. 8:471-481, 1993). Th...

Although the literature on strategic alliances defines the role of information technologies (IT) as important, any reasoned explanation of it is still anecdotic. This study focuses on a particular type of technological relationship between firms and institutions for developing environmental management innovations through virtual cooperation. It goes into particular depth on the economic and str...

To examine relationships and test previous sectional delimitations within Fuchsia, this study used parsimony and maximum likelihood analyses with nuclear ITS and chloroplast trnL-F and rpl16 sequence data for 37 taxa representing all sections of Fuchsia and four outgroup taxa. Results support previous sectional delimitations, except for F. verrucosa, which is related to a Central American clade...

(-)-Verbenone, a monoterpene bicyclic ketone, is a component of the essential oil from rosemary species such as Rosmarinus officinalis L., Verbena triphylla, and Eucalyptus globulus and is used for an herb tea, a spice, and a perfume. In this study, (-)-verbenone was found to be converted to 10-hydroxyverbenone by rat and human liver microsomal cytochrome p450 (p450) enzymes. The product format...
