Allopolyploidization with the merger of the genomes from different species has been shown to be associated with genetic and epigenetic changes. But the maintenance of such alterations related to one parental species after the genome is extracted from the allopolyploid remains to be detected. In this study, the genome of Brassica napus L. (2n = 38, genomes AACC) was extracted from its intergener...

The effect of the drying method applied and subsequent rapeseed storage on changes in phytosterols was determined. After harvest, rapeseeds were dried by the near-ambient method in a thick immobile layer of 2 m and using air heated to a temperature of 60, 80 and 100 °C. Analyses of phytosterol contents were performed immediately after drying and after 6 and 12 months of storage at a temperature...

Various effects on the separation of raw reaction mixture after the ethanolysis of rapeseed oil were investigated. Water addition, initial temperature of separation, centrifugation, ionic compound addition and time effects affecting concentrations of potassium, free glycerol and yield of the ester phase were found out. Centrifugation has the most positive effect. Finally, correlation between co...

Recent molecular data using resynthesized polyploids of Brassica napus established that genome changes can occur rapidly after polyploid formation. In this study we present data that de novo phenotypic variation for flowering time also occurs rapidly after polyploidization. Two initial polyploid plants were developed by reciprocal crosses of B. rapa and B. oleracea followed by chromosome doubli...

Following the identification of the male (S-locus Cysteine Rich/S-locus Protein 11) and female (S Receptor kinase [SRK]) factors controlling self-incompatibility in the Brassicaceae, research in this field has focused on understanding the nature of the cellular responses activated by these regulators. We previously identified the ARM Repeat Containing1 (ARC1) E3 ligase as a component of the SRK...

Mating systems play a central role in determining population genetic structure and the methods to be used to develop new cultivars and preserve the variability of a crop. A Brassica napus crop called nabicol is grown in northwestern Spain. Knowledge on its mating system is needed in order to manage the germplasm correctly and design breeding strategies. The aims of this work were to study the m...

Sex is often conceptualized either as wanted and consensual or as unwanted and nonconsensual, reflecting an implicit model of wanting that is unidimensional and dichotomous and that conflates wanting and consenting. This study had three objectives: developing a multidimensional model for conceptualizing the wantedness of a sexual act, using this model to compare women's experiences with rape an...

This study assessed the relative merits of sociodemographic variables and psychological variables in understanding women’s fear of rape. A comprehensive understanding of the factors involved in women’s fear of rape may allow for more effective interventions with women. Four hundred and eleven women, aged 18 years or older participated in the study, which surveyed their fear of rape and experien...

BACKGROUND AND AIMS Oilseed rape (Brassica napus) is an important oil crop worldwide. The aim of this study was to identify the variation in nitrogen (N) efficiency of new-type B. napus (genome A(r)A(r)C(c)C(c)) genotypes, and to characterize some critical physiological and molecular mechanisms in response to N limitation. METHODS Two genotypes with contrasting N efficiency (D4-15 and D1-1) w...
