Abstract:

The sequencing of the carrot genome was an effort that formally began in 2012 and culminated with the publication and release of the genome in 2016. A full genome sequence provides the ultimate foundation to study genetics, gene function, and evolution of a species. The primary goal of the carrot genome project was to generate a high quality genome assembly. The full genome sequence generated will serve as the standard of comparison for future studies evaluating the breadth of diversity of carrots. To study the evolution of the carrot genome, the whole genome sequence of carrot and 12 other plants were compared, to identify genes in different species that evolved from a common ancestral gene during speciation. These comparisons indicated that several duplications of the whole genome occurred during carrot evolution. The sequencing of the carrot genome provides a foundation for additional studies in plant evolution. Several immediate applications are already being pursued with the development of molecular markers to accelerate progress in carrot breeding programs. The carrot sequencing project will enrich the genomic resources available to plant scientists working with carrot relatives, and with other plants. This research is of interest to molecular biologists, geneticists, vegetable breeders, and nutritionists.
