Abstract
This proposal addresses the isolation of the pollen-specificity determinant of the gametophytic self incompatibility system (pollen-S) of the Solanaceae. A heterologous transposon tagging strategy in Petunia hybrida has identified a number of candidate mutations. A recent model suggests that mutations in pollen-S may be lethal for the male gametophyte and a modified transposon tagging scheme is proposed that addresses this possibility. This scheme takes advantage of transposons that have been shown to be linked to the S locus of Petunia hybrida. A parallel approach relies on a fine scale genetic and physical map around pollen-S using a novel scheme for the pre-selection of recombinants. This map will allow a number of pollen-S candidates to be tested and will provide the basis for a position based cloning strategy. The identification of pollen-S will provide unique insights into molecular recognition in plants and provide important opportunities for the manipulation of plant breeding behaviour.
