Characterization of a grape variety'Koshu' through comparative genomic hybridization and transcriptomic analysis

‘Koshu’的基因组结构与东方葡萄品种的亲缘关系比与西方葡萄品种的亲缘关系更近，与野生葡萄的亲缘关系也有较大差异。尽管‘Koshu’的基因组包含有限数量的特征不同的序列，但这些差异可能不会影响‘Koshu’的特征。转录本分析表明，‘Koshu’果实成熟期间果皮中一些抗病和胁迫反应相关基因的表达水平高于‘霞多丽’。

Genomic structure of 'Koshu' was more closely related with oriental Vitis vinifera cultivars than with occidental cultivars and largely different from that of a wild grape species. Even though the genome of 'Koshu' contained a limited number of characteristically different sequences, these differences probably do not influence the character of 'Koshu'. Transcriptomic analysis revealed that the expression of some disease resistance and stress response related genes in the berry skin of 'Koshu' during ripening was higher than in 'Chardonnay'.
