1. PROMOTORES DE FLOEMA SÃO DIFERENTEMENTE ATIVADOS POR Candidatus Liberibacter asiaticus EM LARANJEIRAS DOCES TRANSGÊNICAS
RESUMO A utilização de promotores preferencialmente expressos em tecidos vegetais específicos é uma estratégia desejável na busca por resistência a patógenos que colonizam tais tecidos. A bacteria Candidatus Liberibacter asiaticus (Las), associada à doença huanglongbing (HLB) em citros, coloniza o tecido floemático. Alguns promotores, além de co

2. Aperfeiçoamento da fermentação de sacarose através da modificação da expressão dos genes SUC2 e AGT1 em linhagens diploides de Saccharomyces cerevisiae. / Improvement of sucrose fermentation by modifying the expression of SUC2 and AGT1 genes in diploid Saccharomyces cerevisiae strains.
Currently, the S. cerevisiae strains used in industrial production of fuel alcohol in Brazil are diploid yeasts that of metabolize sucrose through its extracellular hydrolysis by the periplasmic invertase, followed by the transport of the formed glucose and fructose into the cells, and further metabolism through glycolysis. In this study, utilizing genetic e

3. Eficiência de transformação genética de citrange 'carrizo' com duas construções gênicas
Transformação genética é considerada uma importante ferramenta auxiliar no melhoramento genético de plantas cítricas. Entretanto, a eficiência de transformação pode variar em função de diversos fatores, incluindo a própria construção gênica utilizada. Este trabalho buscou avaliar a eficiência de transformação genética de plantas de citrang

4. Fermentação de mosto industrial por linhagens de Saccharomyces cerevisiae com transportador de sacarose e sobreexpressão de invertase interna: estudo comparativo com linhagens com alta e baixa atividade de invertase externa / Fermentation of industrial must by strains of saccharomyces cerevisiae with sucrose transporter and overexpression of internal invertase: a comparative study with strains with high and low activity of external invertase
O presente trabalho teve como objetivo avaliar o perfil de metabolização de açúcares por linhagens de S. cerevisiae amplamente utilizadas no setor sucroalcoleiro (CAT-1 e BG-1) e uma linhagem geneticamente modificada (HCJ 003) com o propósito de sobreexpressar invertase intracelular e ainda contém transportadores de sacarose de alta afinidade. Para tal

5. Sugar metabolization of Saccharomyces cerevisiae with transporter of sucrose and different invertase activity / Metabolização de açúcares em linhagens de Saccharomyces cerevisiae com e sem transportador de sacarose e diferentes atividades de invertase
The aim of this work was to evaluate the metabolic profile in the utilization of sugars, using different yeast strains (BG-1, CAT-1, FLEISHMANN, PE-2, 1403-7A and LCM001) with different growth medium and also to analyze behavior and the invertase activities of these yeast strains during fermentative process with recycling, similar to the industrial process.

6. Potato sucrose transporter expression in minor veins indicates a role in phloem loading.
The major transport form of assimilates in most plants is sucrose. Translocation from the mesophyll into the phloem for long-distance transport is assumed to be carrier mediated in many species. A sucrose transporter cDNA was isolated from potato by complementation of a yeast strain that is unable to grow on sucrose because of the absence of an endogenous su

7. Enhanced virus isolation by use of the transporter for a regional laboratory.
Transporter tubes with fibroblast monolayers were compared with sucrose-phosphate-glutamate buffer for transport of 385 specimens to a regional laboratory for virus culture. Ninety-two (91%) of 101 viral isolates were recovered in cell culture from the Transporter, as compared with 82 (81%) from sucrose-phosphate-glutamate buffer. Twenty-five (24.7%) of the

8. Pmsuc3: Characterization of a SUT2/SUC3-type sucrose transporter from Plantago major
Higher plants possess medium-sized gene families that encode plasma membrane–localized sucrose transporters. For several plant species, it has been shown that at least one of these genes (e.g., AtSUC3 in Arabidopsis and LeSUT2 in tomato) differs from all other family members in several features, such as the length of the open reading frame, the number of i

9. Downregulating the sucrose transporter VpSUT1 in Verbascum phoeniceum does not inhibit phloem loading
Sucrose is loaded into the phloem in the minor veins of leaves before export. Two active, species-specific loading mechanisms have been proposed. One involves transporter-mediated sucrose transfer from the apoplast into the sieve element-companion cell complex, so-called apoplastic loading. In the putative second mechanism, sucrose follows an entirely sympla

10. Evidence for an essential role of the sucrose transporter in phloem loading and assimilate partitioning.
Sucrose is the principal transport form of assimilates in most plants. In many species, translocation of assimilates from the mesophyll into the phloem for long distance transport is assumed to be carrier mediated. A putative sucrose proton cotransporter cDNA has been isolated from potato and shown to be expressed mainly in the phloem of mature exporting lea

11. SUT2, a Putative Sucrose Sensor in Sieve Elements
In leaves, sucrose uptake kinetics involve high- and low-affinity components. A family of low- and high-affinity sucrose transporters (SUT) was identified. SUT1 serves as a high-affinity transporter essential for phloem loading and long-distance transport in solanaceous species. SUT4 is a low-affinity transporter with an expression pattern overlapping that o

12. The High-Affinity Maltose/Trehalose ABC Transporter in the Extremely Thermophilic Bacterium Thermus thermophilus HB27 Also Recognizes Sucrose and Palatinose
We have studied the transport of trehalose and maltose in the thernophilic bacterium Thermus thermophilus HB27, which grows optimally in the range of 70 to 75°C. The Km values at 70°C were 109 nM for trehalose and 114 nM for maltose; also, a high Km (424 nM) was found for the uptake of sucrose. Competition studies showed that a single transporter recognize
