Applications of the double-barreled data in whole-genome shotgun sequence assembly and analysis

Double-barreled (DB) data have been widely used for the assembly of large genomes. Based on the experience of building the whole-genome working draft ofOryza sativa L. ssp.Indica, we present here the prevailing and improved uses of DB data in the assembly procedure and report on novel applications during the following data-mining processes such as acquiring precise insert fragment information of each clone across the genome, and a new kind of low-cost whole-genome microarray. With the increasing number of organisms being sequenced, we believe that DB data will play an important role both in other assembly procedures and in future genomic studies.
