  1. 1. Characterizaion of the mechanism underlying auxin-induced seed arrest in Arabidopsis thaliana

    University essay from SLU/Dept. Of Plant Biology

    Author : Sowmiya Devi Venkatesan; [2020]
    Keywords : endosperm; hybridization barriers; triploid block; auxins; RNA Polymerase IV; RNA silencing;

    Abstract : In flowering plants, seeds are produced as a result of double fertilization, whereby the haploid egg cell and the diploid central cell fuse with one of the two haploid sperm cells giving rise to a diploid embryo and a triploid endosperm, respectively. The endosperm serves as the major nutrient source for the developing embryo yet the molecular mechanisms pertaining to its development are not fully understood. READ MORE

  3. 2. A search for novel functions in the auxin metabolic pathway

    University essay from SLU/Dept. of Forest Genetics and Plant Physiology

    Author : Ilias El Houari; [2016]
    Keywords : molecular biology; plant physiology; auxin; phytohormones; genetic screening; ethyl methanesulfonate; mapping-by-sequencing; CRISPR Cas9; confocal microscopy;

    Abstract : Auxins are one of the oldest phytohormones known to us, as studies on its physiological effects date back to the end of the nineteenth century. The cardinal auxin in plants is IAA, and attempts have been made to elucidate its biosynthesis and activity for over 70 years. READ MORE

  4. 3. Studies of root formation of micropropagated shoots in vitro and cuttings from light treated mother plants ex vitro

    University essay from SLU/Dept. of Crop Science

    Author : Yvonne Hedman; [2005]
    Keywords : Aristolochia manshuriensis; micropropagating; rooting; etiolation; callus formation; auxins; activated charcoal; riboflavin; dipping solution;

    Abstract : The ornamental plant Aristolochia manshuriensis is difficult to propagate by cuttings and therefore a propagation method in vitro has been developed. However the published method has several limitations due to unpredictable and low rooting percentage as well as low survival rate. READ MORE
