Phenotypical characterization in "Plasmopara halstedii" (sunflower downy mildew) isolates of several races

Phenotypic variation (morphological and pathogenic characters), and genetic variability were studied in 50 isolates of seven Plasmopara halstedii (sunflower downy mildew) races 100, 300, 304, 314, 710, 704 and 714. There were significant morphological, aggressiveness, and genetic differences for pathogen isolates. However, there was no relationship between morphology of zoosporangia and sporangiophores and pathogenic and genetic characteristics for the races used in our study. Also, our results provided evidence that no relation between pathogenic traits and multilocus haplotypes may be established in P. halstedii. The hypothesis explaining the absence of relationships among phenotypic and genetic characteristics is discussed.

New wild Brassica oleracea L. germplasm at its western distribution limit in the Iberian Peninsula

An exploration and collection mission for wild Brassica oleracea populations was carried out in spring and summer of 2013. The aim of this collection was to expand the number of accessions of wild Brassica oleracea available for basic and applied research in plant breeding. In this paper we report a new accession of wild Brassica oleracea in an unexplored coastal area of Galicia, NW Iberian Peninsula. Details of population ecology and vegetation, soil, climate and geographic data were recorded for this population. The “Endangered” threat category for the region is proposed, and actions for in situ and ex situ conservation are proposed. Seeds will be added to the germplasm collections of University of Santiago de Compostela and Misión Biológica de Galicia (CSIC) for further research on diverse aspects of the dynamics and ecophysiology of the population along with characterization and evaluation of useful traits.

Consequences of heat stress on reproduction of cattle

Heat stress represents one of the major environmental factors that adversely affect the reproductive performance of cattle. In this paper the behavioral adjustments, physical mechanisms and physiological responses to heat loss are described; bos indicus adaptive advantages with respect to bos Taurus, pathophysiology of heat stress and heat stress effects in animal reproduction, both the male and the female.

Desire, Resentment and Reprisal: Revisiting the Emotions of Myth in F. Scott Fitzgerald’s The Great Gatsby

This article aims to reassess F. Scott Fitzgerald’s classic The Great Gatsby (1925), taking into consideration the myth-critical hypotheses of philosopher René Girard. Specifically, this essay will analyse the concepts of mimetic desire, resentment and reprisal violence as emotional components of myth, paying close attention to how the reinterpreted mythical pattern of the novel influences the depiction of such emotions as social traits of corruption. Finally, this article will challenge interpretations that have regarded Gatsby as a successful scapegoat-figure, examining instead how the mythical meanings and structures of the text stage an emotional crisis of frustrated desire and antagonism that ultimately offers no hope of communal restoration.

Crossing borders: Space and identity in the essay by Angelina Muñiz

In this study, we establish a relation between the representation of space in Muñiz’s essays and the construction of the essayist’s complex identity which combines Spanish, Jewish and Mexican traits. We concentrate on Angelina Muñiz’s essays Las raíces y las ramas (1993) and El canto del peregrino (1999). Methodologically, we rely on Maingueneau’s concept of ‘scenography’, according to which the text stages its own situation of enunciation. Our starting point is the triple Spanish-Jewish-Mexican identity of the essayist. Our research question is about how the essayist deals with the space corresponding to respectively the Spanish and Mexican part of her identity. Secondly, we analyse the representation in the essays of a space corresponding to her Jewish roots. We find that Muñiz’s vision of space is not static; the essayist’s vision on space is dynamic, open, free and characterized by a constant free movement across national borders. Similar to the concept of space of the ‘diaspora’, her vision is constructed without the limitations imposed by national borderlines or geographical distances.
