  1. 1. 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

  2. 2. Plant Nanobionics : From Localized Carbon Capture to Precision Molecular Delivery

    Författare :Cyril Routier; Eleni Stavrinidou; Magnus Berggren; Seon-Yeong Kwak; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant nanobionics; Nanoparticles; Chitosan-modified polyethyleneimine; Infiltration; CO2 capture; Photosynthesis;

    Sammanfattning : Photosynthesis is an evolutionary marvel that not only sustains plant life but also profoundly shaped the climatic conditions necessary for the development of other advanced forms of life and the ecosystems we know today. During photosynthesis, plants harness the energy of light to convert carbon dioxide (CO2), one of the main greenhouse gases, into sugars for the growth of both themselves and organisms that consume plants, and oxygen that sustains life on Earth.

  3. 3. Calcium transporting ATPases in plant cells

    Författare :Malin Olbe; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Triticum aestivum; calcium; Brij 58; calmodulin; Ca2 signalling; inside-out; endoplasmic reticulum; plant; plasma membrane; proteolysis; P-type ATPase; spinach; Spinacea oleracea; trypsin; two-phase; wheat.; Plant biochemistry; Växtbiokemi;

    Sammanfattning : Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes.

  4. 4. Genetic Control of Annual Growth Rhythm in the Conifer Norway Spruce (Picea Abies L. Karst)

    Författare :Anna Karlgren; Ulf Lagercrantz; Niclas Gyllenstrand; Janice Cooke; Uppsala universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bud set; circadian clock; Picea abies; growth cessation; phosphatidyl ethanolamine-binding protein PEBP genes; Biologi med inriktning mot evolutionär funktionsgenomik; Biology with specialization in Evolutionary Functional Genomics;

    Sammanfattning : Norway spruce (Picea abies L. Karst) is a conifer belonging to the group gymnosperms and is an ecologically and economically important species in several parts of Europe. LÄS MER

  5. 5. Analysis of plant growth regulating substances

    Författare :Barbro Andersson; Bo Jansson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant regulators; phytohormones; pine; spruce; anther; abscisic acid; 3-indoleacetic acid; gibberellin Ag; N- 3-indoleacetyl -aspartic acid; dichlorophene; Amberlite XAD-7; identification; quantification; GC; HPLC; GC-MS; GC-MID; Hormoner;

    Sammanfattning : Natural plant growth regulators (phytohormones) are a group of organic compounds which, in very small amounts, act as regulators of physiological processes in plants.Methods were developed for the analysis of phytohormones in samples from Norway spruce (Picea abies (L.) Karst.) and Scots pine (Pinus sylvestris (L. LÄS MER
