A polynucleotide repeat expansion causing temperature-sensitivity persists in wild irish accessions of arabidopsis thaliana
Tabib, Amanda; Vishwanathan, Sailaja; Seleznev, Andrei; McKeown, Peter C.; Downing, Tim; Dent, Craig; Sanchez-Bermejo, Eduardo; Colling, Luana; Spillane, Charles; Balasubramanian, Sureshkumar (Frontiers Media SA, 2016-08-31)Triplet repeat expansions underlie several human genetic diseases such as Huntington's disease and Friedreich's ataxia. Although such mutations are primarily known from humans, a triplet expansion associated genetic defect ... -
Disaggregating polyploidy, parental genome dosage and hybridity contributions to heterosis in arabidopsis thaliana
Fort, Antoine; Ryder, Peter; McKeown, Peter C.; Wijnen, Cris; Aarts, Mark G.; Sulpice, Ronan; Spillane, Charles (Wiley-Blackwell, 2015-09-23)Heterosis is the phenomenon whereby hybrid offspring of genetically divergent parents display superior characteristics compared with their parents. Although hybridity and polyploidy can influence heterosis in hybrid plants, ... -
Gamete fertility and ovule number variation in selfed reciprocal f1 hybrid triploid plants are heritable and display epigenetic parent-of-origin effects
Duszynska, Dorota; McKeown, Peter C.; Juenger, Thomas E.; Pietraszewska-Bogiel, Anna; Geelen, Danny; Spillane, Charles (Wiley-Blackwell, 2013-01-31)Polyploidy and hybridization play major roles in plant evolution and reproduction. To investigate the reproductive effects of polyploidy and hybridization in Arabidopsis thaliana, we analyzed fertility of reciprocal pairs ... -
Identification of imprinted genes subject to parent-of-origin specific expression in Arabidopsis thaliana seeds
McKeown, Peter C.; Laouielle-Duprat, Sylvia; Donoghue, Mark T.A.; Fort, Antoine; Duszynska, Dorota; Aurélie, Comte; Lao, Nga T.; Spillane, Charles (2011)Background: Epigenetic regulation of gene dosage by genomic imprinting of some autosomal genes facilitates normal reproductive development in both mammals and flowering plants. While many imprinted genes have been identified ... -
Origin of year-long bean (phaseolus dumosusmacfady, fabaceae) from reticulated hybridization events between multiplephaseolusspecies
Mina-Vargas, Angela M.; McKeown, Peter C.; Flanagan, Nicola S.; Debouck, Daniel G.; Kilian, Andrzej; Hodkinson, Trevor R.; Spillane, Charles (Oxford University Press (OUP), 2016-08-06)Background and Aims Improved understanding of the secondary gene pools of crops is essential for advancing genetic gain in breeding programmes. Common bean, Phaseolus vulgaris, is a staple crop with several wild relatives ...
