摘要：
Compositions related to the quantitative trait locus 6 (QTL6) in maize and methodsfor their use are provided. The compositions are novel molecular marker locithat are genetically linked with QTL6 and which are associated with increasedoil content and/or increased oleic acid content and/or an increased oleic acid/linoleicacid ratio of a plant or plant part thereof. These novel markers are characterizedby the presence of at least one polymorphism relative to the corresponding markerlocus 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 maizeDGAT 1-2 polypeptide or biologically active variant thereof. The marker lociof the invention, and suitable fragments thereof, are useful in methods of theinvention for manipulating oil and/or oleic acid content and/or oleic acid/lineolicacid ratio of a plant or plant part thereof, for marker-assisted selection ofa plant, for example, a maize plant, or plant part thereof, having an increasedoil content and/or increased oleic acid content and/or an increased oleic acid/linoleicacid ratio, and for marker- assisted breeding of the high oil and/or high oleicacid trait.
