1. Evidence of genetic differentiation and karyotype evolution of the sedges Cyperus ligularis L. and C. odoratus L. (Cyperaceae)
ABSTRACT The taxonomy of Cyperaceae is complex, with genera like Cyperus harboring species complexes. We analyzed the genetic similarity between Cyperus ligularis L. and C. odoratus L. based on DNA fingerprinting and cytogenetics. Significative genetic differentiation (G ST = 0.363) and low gene flow (N m = 0.877) indicated a clear genetic distinction betwe

2. Capacidade de combinação e depressão por endogamia em populações de milho crioulo
The maize landraces are genotypes that have special features like wide genetic variability, which is noticeable through the color of grain, plant architecture and yield of their representatives. By presenting these different qualitative characteristics becomes important to perform a quantitative characterization of these genotypes for use in maize pre-breedi

3. Efeito da competição dentro de parcelas, da interação genótipos x ambientes e influência de estratégias de seleção no melhoramento genético de eucalipto / Effect of competition within plots, of the genotype x environment interaction and influence of selection strategies in genetic breeding of Eucalypt
The aim was to determine the genetic parameters of progeny tests in Eucalyptus grandis Hill Maiden with 3 years old under competicional effect, as well as to study the genotype x environment interaction and its impact on strategies for direct and indirect selection and analyze different selection strategies like selection among and within, mass, stratified m

4. Polinização e qualidade de sementes produzidas por Pychotria tenuinervis (Rubiaceae) em fragmentos de Mata Atlantica : efeito da distancia de bordas antropicas e naturais
Spatial and temporal climatic variability among areas may affect the reproductive events of plant and animal populations. Habitat changes or abrupt limits between habitats can affect the interactions between plants and their pollen and seed vectors and lead to a decrease in seed quality because of increased inbreeding. The isolation of forest patches and the

5. NÃmero de clones por famÃlia, seleÃÃo clonal e seleÃÃo de famÃlias em programas de melhoramento de batata / Number of clones per family and clonal versus family selection in potato breeding programs.
Potato (Solanum tuberosum L.) breeding programs have the objective of producing superior clones from biparental crosses among many different cultivars. Aiming to get these superior clones breeders evaluate great numbers of clones without giving any attention to the families they came from. Simmonds (1996) suggested that breeders can choose between select clo

6. Reading between the LINEs: Human Genomic Variation Induced by LINE-1 Retrotransposition
The insertion of mobile elements into the genome represents a new class of genetic markers for the study of human evolution. Long interspersed elements (LINEs) have amplified to a copy number of about 100,000 over the last 100 million years of mammalian evolution and comprise ∼15% of the human genome. The majority of LINE-1 (L1) elements within the human g
