  1. 41. Significance of hydrolytic enzymes expressed during xylem cell death

    Författare :Benjamin Bollhöner; Hannele Tuominen; Moritz Nowack; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; Populus; xylem cell death; metacaspase; fiber; lateral root emergence; molekylärbiologi; Molecular Biology; Physiological Botany; fysiologisk botanik; molecular cell biology; molekylär cellbiologi;

    Sammanfattning : Xylem is an inherent feature of all vascular plants and functions in water transport and mechanical support. In order to efficiently transport water, xylem cells are reinforced by secondary walls before they undergo programmed cell death and their cell contents are removed by autolysis to create a hollow tube.

  3. 42. Plant Calreticulins - isoforms, localization and function

    Författare :Karin Svensson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; arabidopsis thaliana; calcium; isoform; endoplasmic reticulum; chaperone; tunicamycin;

    Sammanfattning : Calreticulin (CRT) is an endoplasmic reticulum (ER)-located protein involved in quality control of newly synthesized proteins as well as in calcium homeostasis of the cell. Most of what is known about CRT arises from studies of mammalian systems. LÄS MER

  4. 43. The circadian clock in annuals and perennials : coordination of Growth with Environmental Rhythms

    Författare :Mikael Johansson; Maria E. Eriksson; Paul Devlin; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; circadian clock; arabidopsis; populus; Molecular biology; Molekylärbiologi; Plant biotechnology; Växtbioteknik; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Since the first signs of life on planet earth, organisms have had to adapt to the daily changes between light and dark, and high and low temperatures. This has led to the evolution of an endogenous time keeper, known as the circadian clock. LÄS MER

  5. 44. From green to yellow : a leaf story

    Författare :Olivier Keech; Per Gardeström; Pierre Dizengremel; Lee Sweetlove; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplasts; cytoskeleton; darkness; metabolism; microscopy; mitochondria; microtubules; senescence; system redox; Plant physiology; Växtfysiologi;

    Sammanfattning : När ett blad gulnar genomgår det både morfologiska och metaboliska förändringar. Denna process benämns senescence och en förbättrad förståelse av dess mekanismer är viktiga både ur ett grundvetenskapligt perspektiv och för potentiella bioteknologiska applikationer. LÄS MER

  7. 45. Plasma Membrane Proteomics and Functional Characterization & Expression Profiling of Plant Aquaporins

    Författare :Erik Alexandersson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; phosphorylation; barley; GFP; GUS; quantitative real-time reverse transcriptase PCR; microarray; aquaporin; MIP; Arabidopsis; plasma membrane; proteomics;

    Sammanfattning : In order to identify integral and peripheral proteins associated with the plasma membrane (PM), highly purified Arabidopsis PMs were analyzed by mass spectrometry. In total, 238 putative PM proteins were identified, of which 114 were predicted to have transmembrane domains or to be PM-anchored. LÄS MER
