Functional Genomics of Nectar Production in the Brassicaceae

The molecular events involved in the synthesis and secretion of floral nectar are poorly understood. Indeed, there are no genes known to directly affect the de novo production or quality of floral nectar. To address this gap in knowledge, the long-term goals of this research are to elucidate the underlying mechanisms of nectar production in the agriculturally important Brassicaceae family, and how this understanding can be translated into higher yields in multiple crop species. As an initial step, the means by which the coordinated expression of genes in nectary tissues is involved in the synthesis and secretion of nectar was previously examined using MSI resources. Mutant lines for nectary-specific genes are being isolated and will be partially characterized through a combination of Affymetrix DNA microarray and DNA sequencing analyses. The next step is to use software available through MSI to process the large amounts of data that are produced through this project.
