非洲水稻（Oryza glaberrima）和非洲的种植实践据说影响了美洲新兴的殖民种植园经济1，2。然而，由于书面或植物学记录有限，非洲水稻做法的影响程度难以确定2，3。O. glaberrima在苏里南的稻田马龙人承担有关非洲奴隶和他们的后代，谁在祖先的仪式奉献它的知识高水平的证据4，5。在这里，我们建立了强烈的相似性，因此可能的起源，第一个现存的新大陆地方品种的O。glaberrima到来自西非上几内亚森林的地方品种。我们从苏里南帕拉马里博的一个栗色市场收集了非洲水稻，对其进行了繁殖，对其基因组6进行了测序，并将其与代表O.非洲西部的光果草多样性。通过分析聚类分析中的1，649，769个单核苷酸多态性（SNP），苏里南样本似乎是象牙海岸地方品种的姐妹，并且没有证据表明来自亚洲水稻的基因渗入。尽管荷兰人从加纳、贝宁和中非7带走了大部分奴隶，但奴隶船船长的日记记录了他们在沿着西非海岸航行时购买食物的情况，这为遗传相似性的模式提供了一个可能的解释。这项研究展示了基因组学在理解散居社区的作物文化的基本上不成文的历史。
African rice (Oryza glaberrima) and African cultivation practices are said to have influenced emerging colonial plantation economies in the Americas 1, 2. However, the level of impact of African rice practices is difficult to establish because of limited written or botanical records 2, 3. Recent findings of O. glaberrima in rice fields of Suriname Maroons bear evidence of the high level of knowledge about rice among African slaves and their descendants, who consecrate it in ancestor rituals 4, 5. Here we establish the strong similarity, and hence likely origin, of the first extant New World landrace of O. glaberrima to landraces from the Upper Guinean forests in West Africa. We collected African rice from a Maroon market in Paramaribo, Suriname, propagated it, sequenced its genome 6 and compared it with genomes of 109 accessions representing O. glaberrima diversity across West Africa. By analysing 1,649,769 single nucleotide polymorphisms (SNPs) in clustering analyses, the Suriname sample appears sister to an Ivory Coast landrace, and shows no evidence of introgression from Asian rice. Whereas the Dutch took most slaves from Ghana, Benin and Central Africa 7, the diaries of slave ship captains record the purchase of food for provisions when sailing along the West African Coast 8, offering one possible explanation for the patterns of genetic similarity. This study demonstrates the utility of genomics in understanding the largely unwritten histories of crop cultures of diaspora communities.
