The jujube (Ziziphus jujuba Mill.) (2n=2x=24), native to China, is one of the oldest cultivated fruit tree with more than 7000 years of domestication and utilization history. Jujube is famous as “woody crop” and traditional herbal medicine, and has been the great potential fruit tree and introduced worldwide. Jujube cultivars have been traditionally classified into two major types according to the usage of their fruit, e.g., fresh and dry. The dried jujube accounted for approximately 80% of total production. Recently, the draft sequence of an excellent fresh-cultivar 'Dongzao' has been published, sequencing more genome of jujube will enable us understand the domestication progress, genome evolution and also provide strategies for improvements.'Junzao' is the most dominant jujube cultivar across China, which has reached ca. 35% of cultivation acreage and contributed to 50% of dried-jujube production. Our genomic sequencing provides insights into the variation and evolution of the jujube genome.
