Economic Evaluation of Conservation through Use of an Provenance and Progeny Test.

is a species known for its valuable wood and nuts, but it is threatened with extinction. The plantation of forests for genetic resource conservation is a complementary strategy designed to reduce the species' genetic variability loss. This study aimed to evaluate the technical and economic viability of for genetic conservation through use.

Differential DNA methylation and gene expression during development of reproductive and vegetative organs in Ilex species.

Differential epigenetic (DNA cytosine methylation) and gene expression patterns were investigated in reproductive and vegetative organs from Ilex paraguariensis and I. dumosa, at distinct developmental stages. We aimed at contributing towards elucidating major molecular changes underlying the sexual differentiation processes which, in these dioecious species, are completely unknown.

Unraveling the genetic complexity of a cultivated breeding population of "yerba mate" (Ilex paraguariensis St. Hil.).

We report the first comprehensive multilocus molecular characterization of cultivated Ilex paraguariensis plants belonging to a breeding program. Using nuclear and homologous chloroplastidic molecular markers, we have genotyped 158 plants from four plantation sites. Analyses of the nuclear data (187 variable dominant loci) allowed detecting high diversity (0.
