  1. 1. Endosperm-based postzygotic hybridization barriers in Arabidopsis and Capsella

    University essay from SLU/Dept. Of Plant Biology

    Author : Mohammad Foteh Ali; [2021]
    Keywords : Endosperm development; Parental conflict; Genetic diversity; Auxin;

    Abstract : In Arabidopsis, endosperm development is very important for viable seed development. Especially, endosperm cellularization is a crucial event for embryo survival and if it fails, can lead to embryo arrest, as observed in seeds derived from interploidy and interspecies hybridization.

  3. 2. Identifying Genetic Causes of Hybrid Necrosis in Arrabidopsis lyrata

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Carlos Valbuena-Gonzalo; [2019]
    Keywords : ACD6; deleterious gene interactions; DM9; dwarfism; microsatellites;

    Abstract : Deleterious gene interactions due to accumulation of individual genetic variations between different lineages are a cause of population diversification by creating reproductive barriers that ultimately lead to differentiation of species. One type of deleterious interactions is called “hybrid necrosis”, in which epistatic interactions between some plant immunity genes (usually very variable) cause autoimmunities that produce a necrotic and dwarf phenotype.

  4. 3. Studying genetics of leaf shape variation in Arabidopsis lyrata

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Carina Kvernes Macpherson; [2019]
    Keywords : Arabidopsis lyrata; Arabidopsis arenosa; leaf shape; RCO genes; genotype; phenotype; gene sequence variation;

    Abstract : The relationship between leaf and its environment has resulted in a tremendous diversification of leaf shape within and between plants species, which is important to cope with the differing environmental conditions. Arabidopsis lyrata is a prime model plant that shows leaf shape variation within species and between related species. READ MORE

  5. 4. Molecular and morphological analysis of genetic polymorphisms causing glabrousness in wild populations of Arabidopsis lyrata.

    University essay from Institutionen för livsvetenskaper

    Author : Hanna Engström; [2006]
    Keywords : transformation analysis; SNP; natural variation; Arabidopsis lyrata;

    Abstract : Trichome formation in Arabidopsis lyrata is a naturally occurring trait with phenotypic polymorphisms within wild populations. In Swedish accessions of A. READ MORE
