AbstractModern hulless wheats, Triticum aestivum L., are more susceptible to the wheat midge, Sitodiplosis mosellana (Géhin), than the hulled, wild, ancestral species. Hulless cultivars of barley, Hordeum vulgare L., are becoming more widely grown in western Canada than in the past. Hulled and hulless cultivars of two-rowed and six-rowed barleys were tested for their susceptibility to wheat midge, to determine if this midge might become a serious pest of barley and to assess which plant traits might affect host suitability. In the field, larval populations on 10 barley cultivars were much lowe

Abstract:

AbstractPeroxiredoxins are thiol–requiring antioxidants found in organisms ranging from bacteria to humans. They can be divided into two subgroups with either one or two conserved cysteine residues. In plants, 1–Cys peroxiredoxins have been identified in a number of grasses and cereals, and in the dicotyledonous speciesArabidopsis thaliana. In contrast to other antioxidants, the 1–Cys peroxiredoxin genes are expressed solely in seeds, and only in the parts of the seeds surviving desiccation, i.e. the embryo and the aleurone layer. The expression pattern is characteristic of late embryogenesis–

Seed weight and size assessed by image analysis were compared between two near-isogenic barley lines differing in alleles of the Blp1 gene, which determines melanin accumulation in ear tissues.

Abstract:

Abstract Abscisic acid (ABA) is a phytohormone and a major determinant of seed dormancy in plants. Seed dormancy is gradually lost during dry storage, a process known as ‘after-ripening’, and this dormancy decay is related to a decline in ABA content and sensitivity in seeds after imbibition. In this study, we aimed at investigating the effect of after-ripening on ABA signaling in barley, our cereal model species. Phosphosignaling networks in barley grains were investigated by a large-scale analysis of phosphopeptides to examine potential changes in response pathways to after-ripening. We used

Abstract:

Abstract In C3 cereals such as wheat and barley, grain filling was traditionally explained as being sustained by assimilates from concurrent leaf photosynthesis and remobilization from the stem. In recent decades, a role for ear photosynthesis as a contributor to grain filling has emerged. This review analyzes several aspects of this topic: (i) methodological approaches for estimation of ear photosynthetic contribution to grain filling; (ii) the existence of genetic variability in the contribution of the ear, and evidence of genetic gains in the past; (iii) the controversy of the existence of

Abstract:

Challenge by a nonadapted powdery mildew fungal pathogen leads to the formation of a local cell-wall apposition (papilla) beneath the point of attempted penetration. Several plasma membrane (PM) proteins with opposing roles in powdery mildew infection, including Arabidopsis thaliana PENETRATION1 (PEN1) and barley (Hordeum vulgare) MILDEW RESISTANCE LOCUS O (MLO), are localized to the site of powdery mildew attack. PEN1 contributes to penetration resistance to nonadapted powdery mildews, whereas MLO is a susceptibility factor required by adapted powdery mildew pathogens for host cell entry. Our

Abstract:

In a cell-free system from neutrophil cytosol GTP(γ)S can induce an increase in the number of free filament barbed ends and massive actin polymerisation and cross-linking. GTP(γ)S stimulation was susceptible to an excess of GDP, but not Bordetella pertussis toxin and could not be mimicked by aluminium fluoride, myristoylated GTPgammaS. Gialpha2 or Gbeta1gamma2 subunits of trimeric G proteins. In contrast, RhoGDI and Clostridium difficile toxin B (inactivating Rho family proteins) completely abrogated the effect of GTPgammaS. When recombinant, constitutively activated and GTPgammaS-loaded Rac1,

Abstract:

AbstractWestern boxelder bugs, Boisea rubrolineata (Barber), form large aggregations on pistillate boxelder, Acer negundo L. (Aceraceae), host trees with maturing seeds, and cluster on warm, sunlit surfaces prior to overwintering. We have recently shown that B. rubrolineata is attracted to the host-tree semiochemicals phenylacetonitrile and 2-phenethyl acetate. We report results of chemical analyses and laboratory bioassays suggesting that aggregation and sexual communication in B. rubrolineata are mediated by 2-phenylethanol. This compound serves as an aggregation pheromone for females, males

Abstract:

Apoptotic hepatocytes have been demonstrated to represent an important signal for transmigration of leukocytes sequestered in sinusoids during endotoxemia in vivo. Beside leukocytes, platelets and their adhesion to endothelial cells and leukocytes have been implicated in inflammatory liver injury. Using in vivo multifluorescence microscopy, we examined the possibility that hepatocellular apoptosis causes both leukocytes and platelets to colocalize within the sinusoidal microvasculature of endotoxemic livers. We further addressed the issue whether cellular colocalization with apoptotic hepatocy

Abstract:

Abstract Seeds are complex biological systems comprising three genetically distinct tissues: embryo, endosperm, and maternal tissues (including seed coats and pericarp) nested inside one another. Cereal grains represent a special type of seeds, with the largest part formed by the endosperm, a specialized triploid tissue ensuring embryo protection and nourishment. We investigated dynamic changes in DNA content in three of the major seed tissues from the time of pollination up to the dry seed. We show that the cell cycle is under strict developmental control in different seed compartments. After

Abstract:

IntroductionAccording to Friedrich Nietzsche, the death of Man follows the death of God. Man as a concept must be overcome. Yet Nietzsche extends humanism’s jargon of creativity that privileges Man over animal. To truly overcome the notion of Man, one must undercome Man, in other words go below Man. Once undercome, creativity devolves into a type of building and unbuilding, affording art the ability to conceive of the subject emptied of divine creation. This article will examine how Man is unbuilt in three works by three different artists: Francis Bacon’s “Study of a Baboon” (1953), Jan Švankm
