   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

3. 2. Gibberellin-like substances in seeds during maturation, germination and dormancy release

   Författare :Linda von Schirach-Szmigiel; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This study concerns the induced seed germination with a special reference to the activity of gibberellin-like substances in Phaseolus vulgaris L., Zea mays L. and Rosa rugosa L. LÄS MER

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

   Författare :Maria Svensson; Högskolan i Skövde; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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

7. 5. Molecular Regulation of the Annual Growth Cycle in Populus Trees

   Författare :Domenique André; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Adaptation to the change of seasons is essential for tree survival. Here I show that the phenology of hybrid aspen is regulated by three FLOWERING LOCUS T (FT) genes.FT1, FT2a and FT2b are the result of both a whole genome and a local duplication. LÄS MER
