The focus of research in the Giovannoni laboratory is molecular and genetic analysis of fruit ripening and related signal transduction systems with emphasis on the relationship of fruit ripening to nutritional quality. We are also involved in development of tools for genomics of the Solanaceae including participation in the International Tomato Sequencing Project. We employ several experimental systems but the majority of our work involves the use of tomato. The broad objectives of the lab include deciphering the underlying molecular basis of components of ripening regulation conserved through evolution and how these regulatory networks coordinate ripening events including those related to quality and nutritional content.
Experimental approaches include: 1) positional cloning of loci known via mutation to harbor genes necessary for normal fruit development and ripening, and 2) isolation of candidate ripening regulatory genes based on expression pattern or relationship to ripening-related signal transduction systems (e.g. ethylene, light), and functional analysis in transgenic plants.

- Thousands of years ago, people in the region now known as South America began domesticating Solanum pimpinellifolium, a weedy plant with small, intensely flavored fruit. Over time, the plant evolved […] Read more »
- Tomato breeders have traditionally emphasized traits that improve production, like larger fruits and more fruits per plant. As a result, some traits that improved other important qualities, such as flavor […] Read more »

- Researchers at BTI, Cornell and USDA published a spatiotemporal map of gene expression across all tissues and developmental stages of the tomato fruit – the genetic information underlying how a fruit changes from inside to out as it ripens. Their data is available in the new Tomato Expression Atlas (TEA). Read more »

For more information about the Giovannoni lab, please visit the Plant Biology website. Additionally, the Giovannoni lab, in conjunction with other labs on campus has developed a resource for tomato genomics, the Tomato EST Database. Additional resources and information resulting from tomato genomics activities on the Cornell campus can be found at the Solanaceae Genomics Network site.
