1. The complete chloroplast genome sequences of three Spondias species reveal close relationship among the species
Abstract This study reports the complete chloroplast sequences of three Spondias species. The genome sequences were obtained for Spondias tuberosa, Spondias bahienses, and Spondias mombin using the Illumina sequencing technology by a combination of de novo methods and a reference-guided assembly using Sapindus mukorossi as reference. The genomes of S. tubero

2. Exploring tRNA gene cluster in archaea
BACKGROUND Shared traits between prokaryotes and eukaryotes are helpful in the understanding of the tree of life evolution. In bacteria and eukaryotes, it has been shown a particular organisation of tRNA genes as clusters, but this trait has not been explored in the archaea domain. OBJECTIVE Explore the occurrence of tRNA gene clusters in archaea. METHO

3. The genome sequence of Dyella jiangningensis FCAV SCS01 from a lignocellulose-decomposing microbial consortium metagenome reveals potential for biotechnological applications
Abstract Cellulose and its associated polymers are structural components of the plant cell wall, constituting one of the major sources of carbon and energy in nature. The carbon cycle is dependent on cellulose- and lignin-decomposing microbial communities and their enzymatic systems acting as consortia. These microbial consortia are under constant exploratio

4. Sequence characterization, in silico mapping and cytosine methylation analysis of markers linked to apospory in Paspalum notatum
In previous studies we reported the identification of several AFLP, RAPD and RFLP molecular markers linked to apospory in Paspalum notatum. The objective of this work was to sequence these markers, obtain their flanking regions by chromosome walking and perform an in silico mapping analysis in rice and maize. The methylation status of two apospory-related se

5. Linking dopamine neurotransmission and neurogenesis: the evolutionary history of the NTAD (NCAM1-TTC12-ANKK1-DRD2) gene cluster
Genetic studies have long suggested the important role of the DRD2 gene in psychiatric disorders and behavior. Further research has shown a conjoined effect of genes in the Chr11q22-23 region, which includes the NCAM1, TTC12, ANKK1 and DRD2 genes, or NTAD cluster. Despite a growing need to unravel the role of this cluster, few studies have taken into account

6. Mining plant genome browsers as a means for efficient connection of physical, genetic and cytogenetic mapping: an example using soybean
Physical maps are important tools to uncover general chromosome structure as well as to compare different plant lineages and species, helping to elucidate genome structure, evolution and possibilities regarding synteny and colinearity. The increasing production of sequence data has opened an opportunity to link information from mapping studies to the underly

7. Ferramenta de visualização interativa de comparação entre múltiplos genomas para a identificação de sintenias
A genômica comparativa é uma área de pesquisa que tem como objetivo a busca de como dados genômicos podem estar relacionados entre diferentes espécies. Particularmente, o volume de dados disponibilizados em bancos de dados públicos permite a busca de sintenias entre múltiplos genomas. Um par de genes é dito sintênico quando estes se conservam dentro

8. Association between reproductive traits and four microsatellites in Brangus-Ibagé cattle
The aim of the present study was to verify associations between reproductive efficiency and four microsatellite markers located in synteny with genes involved in the regulation of reproductive mechanisms. A sample of 107 females from a Brangus Ibagé population (5/8 Aberdeen Angus x 3/8 Nelore) was characterized for ETH225 (D9S1) and MM12E6 (D9S20) microsate

9. Synteny of human chromosomes 14 and 15 in the platyrrhines (Primates, Platyrrhini)
In order to study the intra- and interspecific variability of the 14/15 association in Platyrrhini, we analyzed 15 species from 13 genera, including species that had not been described yet. The DNA libraries of human chromosomes 14 and 15 were hybridized to metaphases of Alouatta guariba clamitans, A. caraya, A. sara, Ateles paniscus chamek, Lagothrix lagoth

10. Phylogeny and evolution of the aspartyl protease family from clinically relevant Candida species
Aspartyl proteases are a class of enzymes that include the yeast aspartyl proteases and secreted aspartyl protease (Sap) superfamilies. Several Sap superfamily members have been demonstrated or suggested as virulence factors in opportunistic pathogens of the genus Candida. Candida albicans, Candida tropicalis, Candida dubliniensis and Candida parapsilosis ha

11. Cl gene cluster encoding several small nucleolar RNAs: a comparison amongst trypanosomatids
Small nucleolar RNAs (snoRNAs) are small non-coding RNAs that modify RNA molecules such as rRNA and snRNA by guiding 2'-O-ribose methylation (C/D box snoRNA family) and pseudouridylation reactions (H/ACA snoRNA family). H/ACA snoRNAs are also involved in trans-splicing in trypanosomatids. The aims of this work were to characterise the Cl gene cluster that en

12. Chromosome evolution: Karyotype variability in Platyrrhini and studies of sinteny and homologies between human chromosomes / Evolução cromossômica: estudo da variabilidade cariotípica em Platyrrhini e das homeologias e sintenias com cromossomos humanos
We studied the karyotypes of Brazilian monkeys (Platyrrhini, Primates) using both traditional cytogenetic techniques as well as FISH. FISH analysis employed human probes for chromosome 14, 15 and the X chromosome and a probe of the Y chromosome of Brachyteles arachnoides obtained by chromosome microdissection. Twenty-four individuals of Alouatta guariba clam
