  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
