Whole genome sequencing of Raphanus sativus L.
This study constructed the draft genome of Raphanus sativus, which was sequenced to 122 coverage using next-generation sequencing technology, assembled de novo and then anchored to the genetic linkage map into nine pseudochromosomes. The assembled scaffolds approximately 383 Mb. This genome contains 64,657 gene models. Data is available from the web site of Tokyo University of Agriculture.
Radish (Raphanus sativus L.; 2n=18) is an annual plant species belongs to family Brassicaceae. Radish is of significant agricultural and biological importance as many of the Brassica species that include important vegetable and oil crops. A large number of radish cultivars have been produced and there is a remarkable variation especially in root shapes and sizes (3 ? 200 cm long, 3 ? 50 cm in diameter) and weight (5g ? 30 kg). This genome research project aims to construct a whole genome and expressed sequences of cultivated radish. Radish has a genome of about 574 Mb. Genomic information of radish contributes to promote breeding programs and understand genetic backgrounds of root morphogenesis. In addition, it also contributes to the studies of plant ecological adaptation to weedy and saline habitats because the wild radish races grow in cultivated fields, roadsides, seashores and some are becoming an invasive species and a major agricultural weed.
