1. Expression analysis of cell wall assembly and remodelling-related genes in Arabidopsis roots subjected to boron stress and brassinosteroid at different developmental stages
ABSTRACT Plant cell walls are affected by many biotic and abiotic stress conditions. The aim of this study is to determine the effects of 24-Epibrassinolide (EBL) on some cell wall-related genes in root tissue of five- and ten-week-old Arabidopsis thaliana plants exposed to boron (B) deficiency (0 µM) or toxicity (3000 µM) at the transcriptional level.

2. CPU0213, a novel endothelin type A and type B receptor antagonist, protects against myocardial ischemia/reperfusion injury in rats
The efficacy of endothelin receptor antagonists in protecting against myocardial ischemia/reperfusion (I/R) injury is controversial, and the mechanisms remain unclear. The aim of this study was to investigate the effects of CPU0123, a novel endothelin type A and type B receptor antagonist, on myocardial I/R injury and to explore the mechanisms involved. Male

3. Caracterização funcional de uma xiloglucano galactosiltransferase de Eucalyptus grandis e uma ramnose sintase de Arabidopsis thaliana: Efeitos sobre a estrutura e composição da parede celular primária / Functional characterization of a xyloglucan galactosyltransferase of Eucalyptus grandis and a rhamnose synthase of Arabidopsis thaliana: Effects upon the structure and composition of the primary cell wall
The plant cell wall has been associated with several important biological functions. It surrounds the plant, protecting it against mechanical injuries, biotic and abiotic stresses. In addition, plant cell walls determine cell shape and growth rates. The main constituents of plant cell walls are: cellulose, hemicellulose, pectine, lignin and proteins, which v

4. Isolamento de cDNAs parciais de quatro genes do metabolismo de carboidratos e analise de seus padrões de expressão durante a fase inicial do desenvolvimento de plantulas de jatoba (Hymenaea courbaril L.) / Isolation of four partial cDNA sequences of genes of the carbohydrate metabolism in jatoba (Hymenaea courbaril L.) and their pattern of expression during early seedling growth
The jatobas (species belonging to the genus Hymenaea, family Leguminosae) display large physiological plasticity and as a consequence they have great adaptive capacity to several habitats. Different species and varieties of jatobas have adapted practically to all Brazilian tropical biomes, including the Amazon Forest and the complex of ecosystems that is for

5. Polimorfismo e expressão de genes de celulose sintase em Eucalyptus / Polymorphism and expression of cellulose synthase genes in Eucalyptus
A celulose é um dos biopolímeros mais importantes do planeta, sendo também o mais abundante, e sem dúvida uma característica chave na história evolutiva das plantas. Contudo, sua biossíntese e regulação ainda não são bem compreendidas, embora avanços importantes tenham ocorrido nos últimos anos, sobretudo na identificação de genes e grupos de

6. Anotação e caracterização preliminar de genes de celulose sintase em diferentes espécies de Eucalyptus / Annotation and preliminary characterization of cellulose synthase genes in different species of Eucalyptus
A celulose é o polímero mais abundante do planeta, sendo o principal constituinte da biomassa das plantas. Genes da família CesA, que codificam a enzima celulose sintase foram identificados em diversas espécies de plantas, especialmente em Arabidopsis thaliana, na qual três deles (AtCesA4, AtCesA7 e AtCesA8) foram correlacionados com a produção de cel

7. Anotação e caracterização preliminar de genes de celulose sintase em diferentes espécies de Eucalyptus / Annotation and preliminary characterization of cellulose synthase genes in different species of Eucalyptus
Cellulose is the worlds most abundant polymer, being the main constituent of plant biomass. Genes from CesA family, that encodes the cellulose synthase enzyme, was identified in several plant species, especially in Arabidopsis thaliana, in which three of them (AtCesA4, AtCesA7 e AtCesA8) were associated with secondary cell wall cellulose production.

8. Caracterização farmacologica do relaxamento de corpo cavernoso de coelho induzido pelo veneno de Tityus serrulatus
Títyus serrufatus ís the most dangerous scorpíon of the subfamily Tityinae in Brazíl because of the high toxicity of its venom and its widespread distribution in populous urban centers of southeastern region of the country. The most important clinical manifestations of the human envenomation by Títyus serrulatus are intense local pain and an immediate l

9. A functional cellulose synthase from ascidian epidermis
Among animals, urochordates (e.g., ascidians) are unique in their ability to biosynthesize cellulose. In ascidians cellulose is synthesized in the epidermis and incorporated into a protective coat know as the tunic. A putative cellulose synthase-like gene was first identified in the genome sequences of the ascidian Ciona intestinalis. We describe here a cell

10. Genetic organization of the cellulose synthase operon in Acetobacter xylinum.
An operon encoding four proteins required for bacterial cellulose biosynthesis (bcs) in Acetobacter xylinum was isolated via genetic complementation with strains lacking cellulose synthase activity. Nucleotide sequence analysis indicated that the cellulose synthase operon is 9217 base pairs long and consists of four genes. The four genes--bcsA, bcsB, bcsC, a

11. Identification of a second cellulose synthase gene (acsAII) in Acetobacter xylinum.
A second cellulose synthase gene (acsAII) coding for a 175-kDa polypeptide that is similar in size and sequence to the acsAB gene product has been identified in Acetobacter xylinum AY201. Evidence for the presence of this gene was obtained during analysis of A. xylinum mutants in which the acsAB gene was disrupted (I.M. Saxena, K. Kudlicka, K. Okuda, and R.M

12. Enhancement of cellulose production by expression of sucrose synthase in Acetobacter xylinum
Higher plants efficiently conserve energy ATP in cellulose biosynthesis by expression of sucrose synthase, in which the high free energy between glucose and fructose in sucrose can be conserved and used for the synthesis of UDP-glucose. A mixture of sucrose synthase and bacterial cellulose synthase proceeded to form UDP-glucose from sucrose plus UDP and to s
