  1. 1. Jasmonates in root nodule development

    University dissertation from Stockholm : Botaniska institutionen

    Author : Anna Maria Zdyb; Stockholms universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lotus japonicus; jasmonic acid; actinorhizal; rhizobia; Frankia; root nodule; lipoxygenase; allene oxide cyclase; allene oxide synthase; Casuarina; Datisca; Medicago; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; Plant Physiology; växtfysiologi;

    Abstract : Jasmonic acid (JA), its derivatives and its precursor form a group of phytohormones, the jasmonates, representing signal molecules involved in plant stress responses, in the defense against pathogens as well as in development. Elevated levels of JA have been shown to play a role in arbuscular mycorrhiza and in the induction of nitrogen-fixing root nodules. READ MORE

  2. 2. Conservation of transcription factors in infected cells of nitrogen-fixing root nodules

    University dissertation from Stockholm : Department of Botany, Stockholm University

    Author : Behnoosh Rashidi; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; root nodules; actinorhiza; legumes; infection thread; Frankia; subtilase; leghemoglobin; chitinase; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; Plant Physiology; växtfysiologi;

    Abstract : Infected cells of nitrogen-fixing root nodules are the only plant cells that can stably internally accommodate a eubacterial symbiont. In the context of studying the differentiation of infected cells, we set about to analyse the conservation of infected cell-specific transcription factors using altogether four different promoters from genes showing infected cell-specific expression, or nodule-specific expression.

  3. 3. Control of reactive oxygen species homeostasis in response to environmental stress

    University dissertation from Stockholm : Department of Botany, Stockholm University

    Author : Malgorzata Plaszczyca; Stockholms universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stress; antioxidant defense; ascorbate peroxidase; aerenchyma; actinorhiza; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; Plant Physiology; växtfysiologi;

    Abstract : Plants are exposed to various fluctuations in their environmental conditions - light intensity, temperature, water status - and have to adapt in order to survive. Plant acclimatory responses can include the formation of new tissues, e.g., aerenchyma, or the activation of defense systems, e. READ MORE

  4. 4. The actinorhizal plant Datisca glomerata interpreting its symbiotic adaptations by omics-based comparisons with model and non-model organisms

    University dissertation from Stockholm University : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Marco Salgado; Stockholms universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Root nodule symbiosis; nitrogen fixation; actinorhizal; Datisca glomer-ata; Frankia; nodule development; defensin; antimicrobial; carboxylate transporter; phylogenomics; transcriptomics; växtfysiologi; Plant Physiology;

    Abstract : Nitrogen is the element that most often limits plant growth and development. Common agricultural practices rely on the application of large quantities of industrially-produced nitrogen fertilizer, which poses a worldwide environmental threat. Sustainable agriculture encourages the use of biologically fixed nitrogen. READ MORE
