Chloroplast DNA polymorphism and evolutional relationships between Asian cultivated rice (Oryza sativa) and its wild relatives (O. rufipogon)
Authors: W.J. Li B. Zhang G.W. Huang G.P. Kang M.Z. Liang L.B. Chen
We analyzed chloroplast DNA (cpDNA) polymorphism and phylogenic relationships between 6 typical indica rice, 4 japonica rice, 8 javanica rice, and 12 Asian common wild rice (Oryza rufipogon) strains collected from different latitudes in China by comparing polymorphism at 9 highly variable regions. One hundred and forty-four polymorphic bases were detected.. Read More»

Essential amino acid usage and evolutionary nutrigenomics of eukaryotes - insights into the differential usage of amino acids in protein domains and extra-domains
Authors: L. Santana-Santos, F. Prosdocimi and J.M. Ortega
Nutrigenomics studies the effects of nutrients on the genome, transcriptome and proteome of organisms, and here an evolutionary standpoint on this new discipline is presented. It is well known that metazoan organisms are unable to synthesize all amino acids necessary to produce their proteins and that these essential amino aci.. Read More»

Development and testing of 13 polymorphic microsatellite markers in Larimichthys polyactis (Sciaenidae) using 5' anchored PCR
Authors: C.Y. Ma, H.Y. Ma and L.B. Ma
Larimichthys polyactis is a commercially important marine fish species in southeast Asia. The population crashed due to overfishing in the 1970s, but has since recovered. We developed 13 novel polymorphic microsatellite markers in L. polyactis using 5' anchored PCR. The characteristics of these loci were estimated by analyzing.. Read More»

In silico comparative analysis of tylenchid nematode pectate lyases
Authors: R.M. Moraes Filho and L.S.S. Martins
Phytoparasitic nematodes can infect a wide range of crop plants, and cause billions of dollars of agricultural losses each year. These parasites represent the largest source of biotic stress experienced by plants. The order Tylenchida comprises the most important parasitic nematodes, particularly the root-knot and cyst nematodes. These parasitic organisms.. Read More»

Anthranilate synthase subunit organization in Chromobacterium violaceum
Authors: C.A. Carminatti, I.L. Oliveira, D.O.S. Recouvreux,R.V. Ant�´nio and L.M. Porto
Tryptophan is an aromatic amino acid used for protein synthesis and cellular growth. Chromobacterium violaceum ATCC 12472 uses two tryptophan molecules to synthesize violacein, a secondary metabolite of pharmacological interest. The genome analysis of this bacterium revealed that the genes trpA-F and pabA-B encode the enzymes .. Read More»

Epstein-Barr virus DNA associated with gastric adenocarcinoma and adjacent non-cancerous mucosa in patients from Manaus, Brazil
Authors: P.F. de Aquino P.C. Carvalho J.S. da Gama Fischer A.Q.L. de Souza J.S. Viana S.R.S. Chalub A.D.L. de Souza M.G.C. Carvalho
Gastric cancer is one of most frequent causes of death in Brazil. The city of Manaus has one of the highest incidences of this disease in Brazil. The Epstein-Barr virus (EBV) is a ubiquitous herpesvirus that is classified as a group 1 carcinogen by the International Agency for Research on Cancer. We obtained biopsies from 6 control subjects and 10 patient.. Read More»

Classical and molecular cytogenetic analysis in Chelonoidis carbonaria and Phrynops geoffroanus (Testudines)
Authors: C.E.S. Zago
The number of species of reptiles has decreased since the time that they ruled the Earth until the present days. Turtles have been little studied, particularly regarding their cytogenetics. The present study investigated, using classical and molecular cytogenetic techniques, the chromosomes of Chelonoidis carbonaria, a terrest.. Read More»

Assessing genetic diversity of cotton cultivars using genomic and newly developed expressed sequence tag-derived microsatellite markers
Authors: Y. Zhang, X.F. Wang, Z.K. Li, G.Y. Zhang and Z.Y. Ma
Estimations of genetic diversity and of relationships between varieties are crucial for cotton breeding. The genetic diversity of 59 core cotton cultivars, most of which were collected from China’s main cotton-growing areas, was analyzed based on genomic and newly developed expressed sequence tag-derived microsatellite m..

Phylogeny and systematics of Indian Polygonum sensu lato in the subfamily Polygonoideae based on ITS sequences of nuclear ribosomal DNA
Authors: R.K. Choudhary S.-H. Park J. Lee
The nuclear ribosomal DNA internal transcribed spacer (ITS) sequences from 44 Indian Polygonum taxa were examined to investigate relationships among various sections proposed by earlier researchers. The maximum parsimony trees obtained from analysis of the ITS sequences suggested eight major groups of the Indian Polygonum spp. The relationships among diff.. Read More»

Molecular genetic analysis of the yellow-breasted capuchin monkey: recommendations for ex situ conservation
Authors: C.G. Oliveira, F.A. Gaiotto, M.A. Costa and R.A. Martinez
The yellow-breasted capuchin monkey, Cebus xanthosternos, is one of the most endangered species of the Brazilian Atlantic Forest. In situ conservation for this species is problematic due to habitat destruction; therefore, captive conservation has been considered as an alternative strategy. A Studbook for C. xanthosternos has b.. Read More»
