    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

  4. 4. Elucidating the phytohormonal control of xylem development

    Författare :Johnsson Christoffer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Sammanfattning : Secondary xylem, commonly known as wood, has had a major impact on both our planet and civilization, its uses so ubiquitous that it is often taken for granted in daily life. New challenges imposed by growing population and changing climate have led academia and industries to search for ways of altering wood characteristics to better suit specific purposes. LÄS MER

  5. 5. Studies of genes involved in regulating flowering time in Arabidopsis

    Författare :Maria Svensson; Högskolan i Skövde; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Arabidopsis thaliana; flowering time; fold recognition; GA biosynthesis; promoter trapping; RNA-binding; T-DNA tagging; Biology; Biologi; Naturvetenskap; Natural sciences;

    Sammanfattning : Transition from a vegetative growth phase to flowering in plants occurs in response to both environmental conditions and endogenous signals. Identification of genes that are involved in regulating the time of flowering is of great importance in agri- and horticulture. LÄS MER
