Genetic basis for dosage sensitivity of seed size heterosis in Arabidopsis thaliana
(NUI Galway, 2021-09-08)Heterosis refers to the ability of the F1 offspring to display superior characteristics compared with their parents and despite being genetically studied since the early 1900s, many aspects of this phenomenon remain unclear. ... -
Genome dosage and parent of origin effects in a ploidy series of Arabidopsis thaliana
(2013-11-11)Polyploidy, the presence of more than two sets of chromosomes in an organism, plays major roles in plant evolution, development and function. Understanding the effects of polyploidization at the phenotypic and molecular ... -
Identification of plant-specific components of the Polycomb Group pathway and their roles in the regulation of Arabidopsis thaliana development
(NUI Galway, 2019-09-30)The knowledge about Arabidopsis thaliana developmental life cycle is deep in broad strokes. Nevertheless, the mechanisms that fine tune these phase transitions are still poorly described. One of these mechanisms is the ... -
Molecular genetic investigation towards functions of imprinted genes in reproduction and seed development in Arabidopsis thaliana
(2017-01-26)In flowering plants and placental mammals a subset of genes known as imprinted genes display full or partial suppression or activation to one of its alleles in a parent of origin dependent manner. During maternal and ... -
Nucleolar DNA damage within the female gametophyte perturbs development and genome stability in Arabidopsis thaliana
(NUI Galway, 2021-12-10)The 45S rRNA genes (rDNA) are among the largest repetitive elements in eukaryotic genomes. rDNA consists of tandem arrays of rRNA genes, many of which are transcriptionally silenced. Silent rDNA repeats may act as ‘back-up’ ... -
Reproductive Genetics and Epigenetics of F1 hybrid triploids of Arabidopsis thaliana L.
(2011-12-14)Polyploidy, the occurrence of more than two complete sets of chromosomes in a single nucleus, is an important process contributing to eukaryotic evolution. Polyploidy is also a widespread speciation mechanism and is common ...
