Abstract The regulation of tomato fruit development and ripening is influenced by a large number of loci as demonstrated by the number of existing non-allelic fruit development mutations and a multitude of genes showing ripening-related expression patterns. Furthermore, analysis of transgenic and naturally occurring tomato mutants confirms the pivotal role of the gaseous hormone ethylene in the regulation of climacteric ripening. Here we report RFLP mapping of 32 independent tomato loci corresponding to genes known or hypothesized to influence fruit ripening and/or ethylene response. Mapped ethylene-response sequences fall into the categories of genes involved in either hormone biosynthesis or perception, while additional ripening-related genes include those involved in cell-wall metabolism and pigment biosynthesis. The placement of ripening and ethylene-response loci on the tomato RFLP map will facilitate both the identification and exclusion of candidate gene sequences corresponding to identified single gene and quantitative trait loci contributing to fruit development and ethylene response.
