Number of repetitions for evaluating technological traits in cotton genotypes
Authors: L.P. Carvalho, F.J.C. Farias, C.L. Morello, J.I.S. Rodrigues and P.E. Teodoro
With the changes in spinning technology, technological cotton traits, such as fiber length, fiber uniformity, fiber strength, fineness, fiber maturity, percentage of fibers, and short fiber index, are of great importance for selecting cotton genotypes. However, for accurate discrimination of genotypes, it is important that these traits are evaluated with .. Read More»

Testing the performance of automated annotation of ESTs with the Kegg Orthology (KO) database demonstrates lack of completeness of clusters
Authors: G.R. Fernandes, M.A. Mudado and J.M. Ortega
The KEGG Orthology (KO) database was tested as a source for automated annotation of expressed sequence tags (ESTs). We used a control experiment where every EST was assigned to its cognate protein, and an annotation experiment where the ESTs were annotated by proteins from other organisms. Analyzing the results, we could assig.. Read More»

A procedure to recruit members to enlarge protein family databases - the building of UECOG (UniRef-Enriched COG Database) as a model
Authors: G.R. Fernandes, D.V.C. Barbosa, F. Prosdocimi, I.A. Pena,L. Santana-Santos, O. Coelho Junior, A. Barbosa-Silva, H.M. Velloso, M.A. Mudado, D.A. Natale, A.C. Faria-Campos, S.V. A. Campos and J.M. Ortega
A procedure to recruit members to enlarge protein family databases is described here. The procedure makes use of UniRef50 clusters produced by UniProt. Current family entries are used to recruit additional members based on the UniRef50 clusters to which they belong. Only those additional UniRef50 members that are not fragments.. Read More»

Genetic diversity in natural populations of mangaba in Sergipe, the largest producer State in Brazil
Authors: A.N.R. Soares, M.F. Vit�³ria, A.L.S. Nascimento, A.S. Ledo, A.R.C. Rabbani and A.V.C. Silva
Mangaba (Hancornia speciosa Gomes) is found in areas of coastal tablelands in the Brazilian Northeast and Cerrado regions. This species has been subjected to habitat fragmentation that is mainly due to human activity, and requires conservation strategies. The aim of this study was to analyze the structure and inter- and intrapopulation genetic diversity o.. Read More»

In silico reconstruction of the amino acid metabolic pathways of Trypanosoma cruzi
Authors: A.C.R. Guimar�£es, T.D. Otto, M. Alves-Ferreira, A.B. Miranda and W.M. Degrave
Trypanosoma cruzi is the epidemiological agent of Chagas’ disease, affecting most of Central and South America, constituting a significant health and socio-economic problem. The parasite has a metabolism largely based on the consumption of amino acids, which participate in a diversity of metabolic pathways, leading to ma.. Read More»

Pheno-morphological variation, genetic diversity and population structure of Tunisian Echinus Medic (Medicago ciliaris L.)
Authors: C. Jabri, H. Sbei, N. Zitouna, N. Trifi-Farah and A. Zoghlami Khelil
Medicago ciliaris L., considered as a valuable genetic resource, is a good candidate for the improvement of marginal or degraded lands with low fertility or high salinity. In this study, the pheno-morphological and genetic diversity were investigated in 14 Tunisian populations of M. ciliaris for the first time. Fourteen morphological traits showed signifi.. Read More»

Characterization and comparison of transgenic Artemisia annua GYR and wild-type NON-GYR plants in an environmental release trial
Authors: H. Liu, G.G. Wu, J.B. Wang, X. Wu, L. Bai, W. Jiang, B.B. Lv, A.H. Pan, J.W. Jia, P. Li, K. Zhao, L.X. Jiang and X.M. Tang
The anti-malarial drug, artemisinin, is quite expensive as a result of its slow content in Artemisia annua. Recent investigations have suggested that genetic engineering of A. annua is a promising approach to improve the yield of artemisinin. In this study, the transgenic A. annua strain GYR, which has high artemisinin content, was evaluated in an environ.. Read More»

Biplot analysis of strawberry genotypes recommended for the State of EspÃ?Ârito Santo
Authors: A.F. Costa, P.E. Teodoro, L.L. Bhering, N.R. Leal, F.D. Tardin and R.F. Daher
Most strawberry genotypes grown commercially in Brazil originate from breeding programs in the United States, and are therefore not adapted to the various soil and climatic conditions found in Brazil. Thus, quantifying the magnitude of genotype x environment (GE) interactions serves as a primary means for increasing average Brazilian strawberry yields, an.. Read More»

Establishment of a heterologous system for the expression of Canavalia brasiliensis lectin: a model for the study of protein splicing
Authors: Walderly Melga�§o Bezerra, Cristina Paiva da Silveira Carvalho, Renato de Azevedo Moreira and Thalles Barbosa Grangeiro
During its biosynthesis in developing Canavalia brasiliensis seeds, the lectin ConBr undergoes a form of protein splicing in which the order of the N- and C-domains of the protein is reversed. To investigate whether these events can occur in other eukaryotic organisms, an expression system based on Pichia pastoris cells was es.. Read More»
