Abstract: The use of reverse transcription quantitative PCR technology to assess gene expression levels requires an accurate normalization of data in order to avoid misinterpretation of experimental results and erroneous analyses. Despite being the focus of several transcriptomics projects, oaks, and particularly cork oak (Quercus suber), have not been investigated regarding the identification of reference genes suitable for the normalization of real-time quantitative PCR data. In this study, ten candidate reference genes (Act, CACs, EF-1α, GAPDH, His3, PsaH, Sand, PP2A, ?-Tub and Ubq) were evaluated to determine the most stable internal reference for quantitative PCR normalization in cork oak. The transcript abundance of these genes was analysed in several tissues of cork oak, including leaves, reproduction cork, and periderm from branches at different developmental stages (1-, 2-, and 3-year old) or collected in different dates (active growth period versus dormancy). The three statistical methods (geNorm, NormFinder, and CV method) used in the evaluation of the most suitable combination of reference genes identified Act and CACs as the most stable candidates when all the samples were analysed together, while ?-Tub and PsaH showed the lowest expression stability. However, when different tissues, developmental stages, and collection dates were analysed separately, the reference genes exhibited some variation in their expression levels. In this study, and for the first time, we have identified and validated reference genes in cork oak that can be used for quantification of target gene expression in different tissues and experimental conditions and will be useful as a starting point for gene expression studies in other oaks.

Abstract: a greenhouse experiment with nutrient solution was carried out to verify the effects of phosphorus levels on growth, yield and nitrogen, phosphorus, and potassium contents of 5 grain sorghum cultivars. the plants were grown in 20 1 pots in presence either of full stregth solution, or phosphorus diluted to 0.5, 0.2 and 0.1 of normal concentration, and were harvested at maturity (110 days after germination). at harvest, the plants were split into several parts, oven dried and ground. the samples were then analysed for total nitrogen, phosphorus and potassium. decreasing phosphorus availability caused a cecrease in grain production, although the dry weight of the other plant parts was not affected; sorghum cultivars showed different responses to phosphorus. the levels of phosphorus in nutrient solution had an effect on nitrogen and phosphorus contents, but potassium absorption was not afected. a decrease in translocation of potassium to the sorghum grains with the decrease in phosphorus availability was observed.

Abstract: introduction: data on the relationship between personality profile and nicotine dependence may help health professionals to design and improve programs for the treatment and prevention of this dependence. objective: to investigate the relationship between personality profile and nicotine dependence in a group of smoking undergraduate students. methods: a total of 1,245 undergraduate students were randomly selected among 10,500 students enrolled at the cuiabá campus of ufmt in 2001. a standard questionnaire was applied for social characterization and for the determination of the tobacco consumption pattern, comprising 80 students considered as smokers. these students were then submitted to the fagerstr?m test (1978) for nicotine dependence and to the reduced version of the comrey personality scale (cps), that determines personality dimensions. results: analysis of the mean scores (student's t test) revealed an inversely proportional borderline association between dependence and the order x lack of compulsion scale (p = 0.06), and a negative or inversely proportional association between the cps extroversion x introversion (p = 0.002) and control of validity scales (p = 0.04). linear regression analysis of the fagerstr?m test points confirmed the inversely proportional borderline association between dependence and the order x lack of compulsion (p = 0.06) and cps extroversion x introversion scales (p = 0.02). however, when the interference of daily cigarette consumption was controlled, only the extroversion x introversion scale remained associated with dependence (p = 0.001). conclusion: students who are nicotine-dependent smokers are less extroverted than non-dependent smokers.
