Symbiotic interaction between rhizobia and leguminous plants leads to the formation of N 2 -fixing root nodules. This interaction shows a high degree of host specificity based on the exchange of chemical signals between the symbiotic partners. Although much is known about the bacterial genes required for the establishment of this interaction, less ...
We have used an "offspring cross" mapping strategy in combination with the random amplified polymorphic DNA (RAPD) assay to construct the first genetic map of the species Miscanthus sinensis (2n = 2x = 38). This map is based on an outbred population of 89 individuals resulting from the cross between two genotypes from a previously designed cross. C...
A quantum chemistry based Green's function formulation of long-range charge transfer in deoxyribose nucleic acid (DNA) double helix is proposed. The theory takes into account the effects of DNA's electronic structure and its incoherent interaction with aqueous surroundings. In the implementation, the electronic tight-binding parameters for unsolvat...
During the past 20 years, the flowering plant Arabidopsis thaliana has been adopted as a model organism by thousands of biologists. This community has developed important tools, resources and experimental approaches that have greatly stimulated plant biological research. Here, we review some of the key events that led to the uptake of Arabidopsis a...
This paper describes the construction and characterization of a Brazilian strain of bovine herpesvirus type 1.2a (BoHV-1.2a) with a deletion of the glycoprotein E (gE) gene. The deletion was introduced by co-transfection of a deletion fragment containing the 5´and 3´gE flanking regions and genomic DNA of wild type BoHV-1 into bovine cells. Isolatio...
Présentation d'un nouvel algorithme de recherche de similitudes dans les sequences d'ADN basé sur le regroupement de graines à l'aide de critères statistiques
Recent discoveries that high prolificacy in sheep carrying the Booroola gene (FecB) is the result of a mutation in the BMPIB receptor and high prolificacy in Inverdale sheep (FecXI) is the result of a mutation in the BMP15 oocyte-derived growth factor gene have allowed direct marker tests to be developed for FecB and FecXI. These tests were carried...

In this study we construct a phylogenetic hypothesis for the relatedness among disjunct subspecies of Cyclamen repandum and its two allopatric congeners, C. creticum and C. balearicum in order to examine the evolutionary divergence of currently isolated populations across the western Mediterranean. The most parsimonious phylogenetic tree obtained f...
We have evaluated whether sequence polymorphisms in the rRNA intergenic spacer region can be used to study the relatedness c.' two subspecies of Trypanosoma brucei. Thirteen T. bnrcei isolates made up of 6 T. b. brucei and 7 T. b. gambiense were analyzed using restriction fragment length polymorphism (RFLP). By PCR-based restriction mapping of the ...
