Physiological, biochemical and molecular factors associated with heat tolerance in bentgrass (Agrostis spp.)
No full textHigh temperature is a major factor limiting the growth of cool-season plant species during summer. Understanding mechanisms of plant tolerance to high temperature would help develop effective management practices and heat-tolerant cultivars through breeding or biotechnology. This dissertation research explored physiological, biochemical and molecular mechanisms for improving heat tolerance in two bentgrass species, creeping bentgrass (Agrostis stolonifera L.), a widely used cool-season grass species on golf course tees and putting greens, and thermal rough bentgrass (Agrostis scabra Willd.) adapted to geothermal areas in Yellowstone National Park. The dissertation reports research in three main components. The first section compared differential heat-induced metabolism of hormones, proteins and metabolites between heat-sensitive creeping bentgrass and heat-tolerant A. scabra. Based on the findings that heat tolerance of bentgrass was associated with changes in stress-related hormone levels, the effects of foliar-applied hormone or hormone inhibitors on creeping bentgrass to enhance heat tolerance were further studied. Results from both growth chamber and field studies confirmed the effectiveness of applying hormones or hormone-based plant growth regulators on alleviating heat injuries in creeping bentgrass. In the last part of the dissertation, a few transgenic creeping bentgrass lines with improved heat tolerance were characterized. These transgenic lines carry a gene (ipt) controlling cytokinin synthesis. Increased ipt gene expression and cytokinin levels were confirmed and changes in morphological and physiological traits of the plants were examined. Genome-wide protein responses to the addition of the gene and their association with heat tolerance were discussed. The results indicated that transformation with the ipt gene induced protein changes involved in multiple functional groups, mainly in energy, protein destination and storage, and disease/defense categories in both leaves and roots of creeping bentgrass, thus cytokinins may have regulatory roles in multiple metabolic pathways for heat tolerance. Taken together, these studies suggest summer performance of creeping bentgrass may be improved by properly applying hormone-based plant growth regulators or biostimulants, and incorporating molecular markers developed from heat- and/or hormone-responsive proteins and metabolites may facilitate selection of heat-tolerant creeping bentgrass cultivars.Ph.D.Includes abstractVitaIncludes bibliographical referencesby Yan X
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
