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 ... -
Genome dosage, genetic hybridity and crop improvement
(NUI Galway, 2020-03-02)Plant breeding is focussed on introducing novel traits in plants, as well as enhancing or repressing traits already present. A noble objective in agriculture is to produce more food per unit area with overall fewer resources. ... -
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 ...
