Análise da variabilidade genética de acessos dePsidium spp. (Myrtaceae) avaliados quanto à reação a Meloidogyne enterolobii

This study aimed to characterize molecular of 13 accessions of Psidium spp. (Myrtaceae) that was been identified for the reaction to rootknot guava nematode. The DNA extraction of the samples was carried according to the protocol of Shillito & Saul (1988). The molecular markers type fAFLP, were obtained from fAFLP Regular Plant Genomes Fingerprinting Kit' (Applied Biosystems from Brasil Ltda.) and were tested 24 selectives combinations of primers, of which 18 showed amplification that produced 272 polymorphic markers. To the analysis of the markers were employed the softwares GeneScan (ABI Prism versao 1.0) and Genotyper (ABI Prism version 1.03), and the data collected were transformed into a binary matrix that was analyzed in the software PAUP (Phylogenetic Analysis Using Parcimony - version 3.01). Were calculated genetic distance index intra and interespecific between the genotipes. It was found that the AFLP markers were efficient in the discrimination between accessions, as well as in showing genetic similarity among accessions identified as resistant to the nematode Meloidogyne enterolobii, which could be discussed in the future.

The Genome Sequence of Taurine Cattle: A Window to Ruminant Biology and Evolution

To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a higher density of segmental duplications, enrichment of repetitive elements, and species-specific variations in genes associated with lactation and immune responsiveness. Genes involved in metabolism are generally highly conserved, although five metabolic genes are deleted or extensively diverged from their human orthologs. The cattle genome sequence thus provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production.

Magnetic response and critical current properties of mesoscopic-size YBCO superconducting samples

In this contribution superconducting specimens of YBa(2)Cu(3)O(7-delta) were synthesized by a modified polymeric precursor method, yielding a ceramic powder with particles of mesoscopic-size. Samples of this powder were then pressed into pellets and sintered under different conditions. The critical current density was analyzed by isothermal AC-susceptibility measurements as a function of the excitation field, as well as with isothermal DC-magnetization runs at different values of the applied field. Relevant features of the magnetic response could be associated to the microstructure of the specimens and, in particular, to the superconducting intra- and intergranular critical current properties.

Retornos crescentes e decrescentes e firma representativa: uma visão do Simpósio de 1930

This paper objective is to analyze the Theory of Increasing and Diminishing Returns from the perspective of the Symposium of 1930, written by Robertson, Sraffa and Shove. Besides these authors, are also treated other texts Robetson and Sraffa, and texts by Pigou and Robbins, expressing the similarity and difference of thought of each author with respect to the Laws

NN -> NN pi(+) reaction near threshold in a chiral power counting approach

Power-counting arguments are used to organize the interactions contributing to the NN-->d pi,pn pi reactions near threshold. We estimate the contributions from the three formally leading mechanisms: the Weinberg-Tomozawa (WT) term, the impulse term, and the Delta-excitation mechanism. Subleading but potentially large mechanisms, including S-wave pion rescattering, the Galilean correction to the WT term, and short-ranged contributions are also examined. The WT term is shown to be numerically the largest, and the other contributions are found to approximately cancel. Similarly to the reaction pp-->pp pi(0), the computed cross sections are considerably smaller than the data. We discuss possible origins of this discrepancy.
