Genomic data of the pear (Pyrus bretschneideri)

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). 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.The assembled scaffolds of high quality sequences total 57 Gb. We identified 42,812 protein-coding genes.

梨（Pear）是仅次于葡萄与苹果的第三大温带核心果树物种，隶属于蔷薇科（Rosaceae）苹果亚科（Pomoideae）。绝大多数栽培梨为功能性二倍体（2n=34）。梨属（Pyrus）遗传多样性丰富，拥有数千个栽培品种，可划分为两大类群：西洋梨（欧洲梨）与东方梨（亚洲梨）。本研究依托HiSeq 2000测序平台，对一系列不同插入片段长度（170bp、500bp、800bp、2kb、5kb、10kb、20kb及40kb）的文库所产出的短读长序列进行测序，基因组测序深度约为107×。最终组装得到的高质量支架序列（scaffold）总长度达57 Gb，共注释得到42812个蛋白质编码基因。
