  2. 1. Understanding and manipulating primary cell walls in plant cell suspension cultures

    Author : Felicia Leijon; Vincent Bulone; Katja Salomon Johansen; KTH; []
    Keywords : Callose synthase; carbohydrate-binding module; cell wall engineering; cellulose microfibril; cellulose nanocrystal; glycosyltransferase; mass spectrometry; plasmodesmata; Populus; primary cell wall; radiometric assay; spectrophotometric assay; Biotechnology; Bioteknologi;

    Abstract : The cell wall is required for many aspects of plant function and development. It is also an accessible and renewable resource utilized both in unrefined forms and as raw material for further development. Increased knowledge regarding cell wall structure and components will contribute to better utilization of plants and the resources they provide. READ MORE

  4. 2. Understanding the Molecular Basis of Differential Growth during Apical Hook Development

    Author : Kristoffer Jonsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Plants’ adaptation to their environment often involves change in development, which in many cases involves the establishment of differential growth rates across organs, for instance during phototropic and gravitropic responses. A striking example of differential growth is the formation of the apical hook, a structure that forms to protect the apical meristem as seedlings penetrate through soil. READ MORE

  5. 3. Plant pathogen defense: Signalling, resistance and cell death

    Author : Oskar N. Johansson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pseudomonas; cell death; pathogens; plant defense; hypersensitive response; glycolipid; reactive oxygen species; blumeria graminis; erysiphe pisi;

    Abstract : Pathogenic microorganisms are present everywhere in nature and infect both animals and plants. Phytopathogenic microorganisms cause diseases on plants, and are responsible for crop loss amounting in the order billions of dollars annually. READ MORE

  6. 4. The significance of ethylene and ETHYLENE RESPONSE FACTORS in wood formation of hybrid aspen

    Author : Bernard Wessels; Hannele Tuominen; Judith Felten; Totte Niittylä; Kurt Fagerstedt; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ethylene; wood formation; hybrid aspen; Populus; ETHYLENE RESPONSE FACTOR; ERF85; ERF139; cambium; lignin; xylem expansion; secondary cell wall; tension wood; cambial derivative cell fate; vessel element; time-lapse photography; molekylär bioteknik inst f nat vet biokemi ; molecular biotechnology dept of biochem ; genetik; Genetics; Physiological Botany; fysiologisk botanik;

    Abstract : The woody tissues serve to stabilise plants, store nutrients and translocate water and minerals. The formation of wood, or ’secondary xylem’, follows a well-defined developmental gradient which is initiated by cell division activity in the vascular cambium. READ MORE

  7. 5. Computerized Cell and Tissue Analysis

    Author : Azadeh Fakhrzadeh; Gunilla Borgefors; Cris Luengo Hendriks; Lena Holm; Nasir Rajpoot; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Image processing; Cell; Tissue; Segmentation; Classification; Histology; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : The latest advances in digital cameras combined with powerful computer software enable us to store high-quality microscopy images of specimen. Studying hundreds of images manually is very time consuming and has the problem of human subjectivity and inconsistency. READ MORE
