1. Chromosome mapping of repetitive sequences in four Serrasalmidae species (Characiformes)
The Serrasalmidae family is composed of a number of commercially interesting species, mainly in the Amazon region where most of these fishes occur. In the present study, we investigated the genomic organization of the 18S and 5S rDNA and telomeric sequences in mitotic chromosomes of four species from the basal clade of the Serrasalmidae family: Colossoma mac

2. Avaliação in silico do transcriptoma do café : identificação de SNPs e inferência de mecanismos de regulação da expressão gênica / In silico analysis of the coffee transcriptome : identification of SNPs and inference of mechanisms of gene expression regulation
Coffee is one of the most important crops in the world, being worldwide consumed and having significant participation in under development economies. Coffea arabica and Coffea canephora are responsible for 70% and 30% of commercial production, respectively. Cytogenetic analysis established that C. arabica is an autogamous alotetraploid formed by a recent (1

3. Evidence for a common sex determination mechanism for pistil abortion in maize and in its wild relative Tripsacum
Cultivated maize (Zea mays) and several other members of the Tribe Andropogoneae produce unisexual florets. In maize, the formation of two staminate florets in each spikelet on the tassel and a single pistillate floret in each spikelet on the ear includes a pistil abortion process that requires the action of the TASSELSEED2 gene. In Eastern gamagrass (Tripsa

4. The mismatch repair system reduces meiotic homeologous recombination and stimulates recombination-dependent chromosome loss.
Efficient genetic recombination requires near-perfect homology between participating molecules. Sequence divergence reduces the frequency of recombination, a process that is dependent on the activity of the mismatch repair system. The effects of chromosomal divergence in diploids of Saccharomyces cerevisiae in which one copy of chromosome III is derived from
