As a noxious weed, weedy rice ( f. Roshev. 1931) has threatened global food security and sustainable crop production. On the other hand, weedy rice has a strong tolerance for abiotic stresses and the potential to provide rich resources for rice genetic improvement. Thus, for a more comprehensive understanding of its speciation, we sequenced and assembled the first complete chloroplast genome of f. ( type). The complete chloroplast genome was 134,555 bp in length and encoded 133 genes, including 83 protein-coding genes, 42 tRNA genes and 8 rRNA genes. Phylogenetic analysis revealed that the indica-japonica differentiation of weedy rice was closely related to cultivated rice, and f. ( type) was genetically more closely clustered with cultivated rice ( type) than or other wild rice.
作为一种有害杂草,杂草稻(f. Roshev. 1931)已威胁到全球粮食安全和作物的可持续生产。另一方面,杂草稻对非生物胁迫具有较强的耐受性,并且有可能为水稻遗传改良提供丰富的资源。因此,为了更全面地了解其物种形成,我们对f. (模式)的首个完整叶绿体基因组进行了测序和组装。完整的叶绿体基因组长度为134,555 bp,编码133个基因,包括83个蛋白质编码基因、42个tRNA基因和8个rRNA基因。系统发育分析表明,杂草稻的籼粳分化与栽培稻密切相关,并且f. (模式)在遗传上与栽培稻(模式)的聚类比或其他野生稻更为紧密。
