1. 26. Characterisation of actin cytoskeletal functions and interactions during planar polarity formation in Arabidopsis

   Författare :Christian Kiefer; Markus Grebe; Tijs Ketelaar; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The establishment of cell and tissue polarity is essential for the development of eukaryotic organisms including plants and animals. When cell polarity is uniformly organised within a plane of a single tissue layer, it is referred to as planar polarity. LÄS MER

3. 27. Phenolics, Nitrogen, and Biotic Interactions : A Study of Phenylpropanoid Metabolites and Gene Expression in the Leaves of Populus tremula

   Författare :Vicki Huizu Decker; Benedicte Riber Albrectsen; George Newcombe; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Populus tremula; condensed tannins; salicinoids; phenolics; genetic variation; soil nitrogen fertilization; herbivory; biology; biologi;

   Sammanfattning : European aspen (Populus tremula) is a fast growing tree species, rich in phenolic compounds. Defense theories suggest that soil nitrogen greatly influence plant allocation togrowth and defense; however, the allocation priorities are not well understood. LÄS MER

4. 28. Dissecting sterol function during clathrin-dependent endocytosis and cytokinesis in Arabidopsis thaliana

   Författare :Márcia Frescatada-Rosa; Markus Grebe; Wolfgang Lukowitz; Umeå universitet; []
   Nyckelord :Arabidopsis; membrane; sterols; cytokinesis; KNOLLE; endocytosis; clathrin; DRP1A; Developmental Biology; miljömedicinsk utvecklingsbiologi; molekylärbiologi; Molecular Biology; molecular cell biology; molekylär cellbiologi;

   Sammanfattning : Sterols are lipid components of eukaryotic membranes. Alterations of membrane sterol composition perturb the execution of cell division, which in diverse eukaryotes can have severe consequences for development of the organism. Partitioning of the cytoplasm during cell division occurs at the final stage of cell division named cytokinesis. LÄS MER

5. 29. Programmed Cell Death in Xylem Development

   Författare :Laetitia Charleen Courtois-Moreau; Hannele Tuominen; Stefan Jansson; Christina Dixelius; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PCD Programmed Cell Death ; Xylem; Apoptosis; Autophagy; Secondary Cell Walls; Microscopy; Microarrays; Comet Assay; TUNEL Assay; Cell and molecular biology; Cell- och molekylärbiologi;

   Sammanfattning : Concerns about climate changes and scarcity of fossil fuels are rising. Hence wood is becoming an attractive source of renewable energy and raw material and these new dimensions have prompted increasing interest in wood formation in trees, in both the scientific community and wider public.

7. 30. Using systems genetics to explore the complexity of leaf shape variation in Populus tremula

   Författare :Barbara Terebieniec; Nathaniel Street; Chung-Jui Tsai; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Populus; Arabidopsis; systems biology; systems genetics; spatial transcriptomics ST ; single nucleotide polymorphism SNP ; Genome wide associations study GWAS ; expression GWAS eGWAS ; molekylärbiologi; Molecular Biology;

   Sammanfattning : Leaves are essential for sustaining humanity as they function as the energy and oxygen-producing organ of plants. Intensive research on physiological processes has contributed immensely to our understanding of the function of leaves. However, comparatively little is known about how leaf size and shape is determined. LÄS MER
