Relationships between Iraqi Rice Varieties

In this project, five varieties of Oryza sativa were obtained from Baghdad/Iraq, and the whole genomic DNA was sequenced, among these varieties, Amber33, Furat, Yasmin, Buhooth1 and Amber al-Baraka. We reported the whole chloroplast genome sequence for Iraqi rice and compared it with the whole chloroplast sequence of other domesticated Asian rice varieties. This provided an important tool for estimating genetic distance and determining evolutionary relationships between rice accessions; the nuclear genomes also provided further information on the relationships between the varieties studied. The study aimed to determine the origin and evolution of Iraqi rice, especially Amber33.

本研究从伊拉克巴格达地区获取了5份栽培稻（Oryza sativa）种质，分别为Amber33、Furat、Yasmin、Buhooth1及Amber al-Baraka，并完成了其全基因组DNA的测序。本研究首次报道了伊拉克水稻的完整叶绿体基因组序列，并将其与其他驯化亚洲稻品种的叶绿体全基因组序列开展比对分析。该序列可为估算水稻种质间的遗传距离、解析其进化关系提供关键的研究工具；核基因组数据也可为明确本研究所涉稻种间的亲缘关系提供进一步的信息支撑。本研究的核心目标为阐明伊拉克水稻的起源与演化历程，其中尤以Amber33为重点研究对象。
