Carrot (Daucus carota L.) is one of the most economically important root vegetables in the world, providing numerous nutrients for human health. China is the largest country of carrot production in the world, and ‘Kurodagosun’ has been a major carrot variety in China. Carrot material used in this study was the inbred line ‘DC-27’, which was derived by forced selfing from ‘Kurodagosun’. To understand the genetic system and plant-specific genes of ‘Kurodagosun’, we report the draft genome sequence of carrot ‘DC-27’ assembled using a combination of Roche454 and HiSeq 2000 sequencing technologies to achieve 32-fold genome coverage. A total of 31,891 predicted genes were identified. These assembled sequences provide candidate genes involved in biological processes including stress response and carotenoid biosynthesis. Genomic sequences corresponding to 371.6 Mb was less than 473 Mb, which is the estimated genome size. The availability of a draft sequence of the ‘DC-27’ genome advances knowledge on the biological research and breeding of carrot, as well as other Apiaceae plants. The ‘DC-27’ genome sequence data also provide a new resource to explore the evolution of other higher plants.
