Amplificação, clonagem e sequenciamento de promotores de café (Coffea arabica cv Mundo Novo) específicos de fruto e ubíquos

The Coffee Genome Project made available to the scientific community relevant information that made practical the identification and cloning of important genes, as well as the identification of the major sequences involved on their regulation. The aim of the present study was to amplify, clone and sequence coffee promoters with specific expression patterns. For that, coffee ESTs which known expression profiles were employed. First, the promoter regions of coffee genes showing, respectively, fruitspecific and ubiquitous expression were amplified using the Genome Walking strategy. Amplified sequences were then inserted in the pGEM-Teasy vector (Promega) and sequenced. Once completed the sequencing, an expression cassette was constructed using the binary vector pCAMBIA-1381z (Cambia). These expression cassettes were cloned into Agrobacterium tumefaciens, and transgenic tobacco plants were generated aiming the functional characterization of these promoters

Avaliação da diluição do DNA extraido de material parafinado para amplificação em PCR

Introduction: Several reasons may lead to the failure of polymerase chain reaction (PCR) using DNA purified from paraffin-embedded materials: presence of inhibitors and degradation of target DNA. DNA dilution will often reduce the concentration of potential inhibitors and still contain enough DNA to allow PCR amplification. Objective: To evaluate the dilution influence of DNA purified from paraffin-embedded materials on β-globin PCR amplification. Material and Method: Paraffin-embedded blocks from 30 patients with oropharynx squamous cell carcinomas, diagnosed and treated at the Oral Oncology Center were selected. DNA extraction was performed using QIAmp minikit (Quiagen). DNA was quantified and evaluated for purity by spectrophotometer analysis. Two groups were formed with different amounts of DNA: group I had the originally extracted DNA and group II had the same DNA, however diluted with ultrapure water addition. PCR was performed in both groups using oligonucleotides for human β-globin gene. Results: For Group I, amplification of the β-globin gene sequence was successful in 33.33% of the samples and for Group II, in 23.33%. Conclusion: Dilution of the DNA extracted of paraffin-embedded materials did not modify statistically the amount of positive samples β-globin gene amplified in PCR, although the results suggest that this is a way to increase the method for efficacy amplification of PCR.
