It also facilitates the production of a group of apocarotenoids – organic chemicals that work as signaling molecules influencing a variety of responses in plants including environmental stresses.The compounds also have a variety of floral and fruity odors that are important in tomato taste.The rare version of TomLoxC was found in only 2% of older or heirloom cultivated large tomato varieties, although the version was present in 91% of currant-sized wild tomatoes, primarily Solanum pimpinellifolium, the wild predecessor of the cultivated tomato.It is becoming more common in newer varieties, suggesting the industry’s shift in focus.”It appears that there may have been strong selection pressure against or at least no selection for the presence of this version of TomLoxC early in the domestication of tomatoes,” Giovannoni added.”The increase in prevalence of this form in modern tomatoes likely reflects breeders’ renewed interest in improved flavor.”With the availability of this wide array of specific genetic information, breeders should be able to work quickly to increase the flavor of store-bought, mass production tomatoes while preserving the traits that make them an economically advantageous crop, noted the United States Department of Agriculture (USDA).”These novel genes discovered from the tomato pan-genome added substantial information to the tomato genome repertoire and provide additional opportunities for tomato improvement. The presence and absence profiles of these genes in different tomato populations have shed important lights on how human selection of desired traits have reshaped the tomato genomes,” said Fei.The scientists expect the addition of nearly 5,000 genes to the tomato genome repertoire will provide additional opportunities for improvement as their roles in tomato biology and fruit quality are determined.Their research involved collaboration with the University of Florida, The Pennsylvania State University, the University of Valencia, the University of Georgia and the Chinese Academy of Sciences, with support from the USDA’s Agricultural Research Service, U.S. National Science Foundation, BARD, the U.S.-Israel Binational Agricultural Research and Development Fund, and Vaadia-Bard Postdoctoral Fellowship Award.
