Abstract
Compositions related to the quantitative trait locus 6 (QTL6) in maize and methods for their use are provided. The compositions are novel molecular marker loci that are genetically linked with QTL6 and which are associated with increased oil content and/or increased oleic acid content and/or an increased oleic acid/linoleic acid ratio of a plant or plant part thereof. These novel markers are characterized by the presence of at least one polymorphism relative to the corresponding marker locus from the QTL6 region of non-high-oil, non-high-oleic acid maize plants. In some embodiments, the novel marker loci comprise coding sequence for a maize DGAT1-2 polypeptide or biologically active variant thereof. The marker loci of the invention, and suitable fragments thereof, are useful in methods of the invention for manipulating oil and/or oleic acid content and/or oleic acid/lineolic acid ratio of a plant or plant part thereof, for marker-assisted selection of a plant, for example, a maize plant, or plant part thereof, having an increased oil content and/or increased oleic acid content and/or an increased oleic acid/linoleic acid ratio, and for marker-assisted breeding of the high oil and/o…
