‘s research encompasses the molecular and classical genetics of tomato; wide hybridization and interspecific incompatibility; use of molecular markers in breeding; and germplasm conservation. His work on reproductive barriers is revealing how plants control pollination to avoid both inbreeding and excessive outcrossing. Using this information, he is developing new types of prebred germplasm sources that broaden the genetic base of cultivated tomato. These research projects are synergistic with the C.M. Rick Tomato Genetics Resource Center, a national and international genebank of tomato wild species and genetic stocks. The Rick Center distributes seed samples to interested researchers, breeders and educators around the world.
Talk title: Charlie Rick and the Origins of the Tomato Genetics Resource Center
During his 60-year career at UC-Davis, the late Prof. Charles M. Rick isolated and mapped hundreds of mutants, collected wild tomato relatives throughout South America, and founded a seed bank to preserve these and other stocks. His work helped establish tomato as a model system for genetic studies, and made available rich germplasm resources with which to analyze the Solanum genome. Rick led 13 major expeditions to the native region to collect and study wild tomatoes. His photographic and written account of these trips form the basis for this retrospective view of the ups and downs of plant collecting in the Andean region and the Galapagos Islands. The C.M. Rick Tomato Genetics Resource Center, established in 1976, now maintains and distributes over 3,900 accessions of wild species and genetic stocks. Current research on wide hybridization and self- and interspecific incompatibility is generating new sources of germplasm and fresh insights into reproductive barriers between tomato and its wild relatives.

Pat Bedinger, Barriers to Breeding session
investigated the genetics of pollen development and the cell biology of pollen tube growth for a number of years. More recently she has refocused her research on a fundamental biological question: how do closely related species occurring in sympatry avoid hybridization? In particular, her current research aims to elucidate the molecular mechanisms underlying reproductive isolation between species, and how mutations can impact species interactions. This highly integrative project involves a team of researchers with expertise encompassing bioinformatics, evolution, genetics and molecular biology. The study system for the project is the tomato clade of Solanum
, which, in addition to the cultivated tomato, includes a diverse set of wild species found Ecuador, Peru and Chile.

Talk title: Phytophthora Blight in Potato: Tipping the Balance Between Resistance and Susceptibility
Salomé Prat, Tubers and Root Systems session
‘s research group aims to identify which signaling cascades govern etiolated seedling development in the dark and how these cascades are affected by light, with a particular focus in the mechanisms involved in integration of the light signal with the own running developmental programs of the plant. The plant hormones gibberellins (GA) and brassinosteroids (BRs) play a central role in transducing the light signal as judged from the dark de-etiolated phenotype of mutants with a block in the synthesis or response to these hormones.
