Genomic data of the pear (<em>Pyrus bretschneideri</em>).

Pear, the third most important temperate fruit species after grape and apple, belongs to the subfamily Pomoideae in the family Rosaceae. The majority of cultivated pears are functional diploids (2n = 34). The Pyrus genus is genetically diverse with thousands of cultivars, but it can be divided into two major groups, Occidental pears (European pears) and Oriental pears (Asiatic pears). <br>We sequenced the genome to a depth of approximately 107 X with short reads from a series of libraries with various insert sizes ( 170bp, 500bp, 800bp, 2kb, 5kb, 10kb, 20kb and 40kb) on a HiSeq 2000 sequencer.<br>The assembled scaffolds of high quality sequences total 57 Gb. We identified 42,812 protein-coding genes.
