Pearl millet [Cenchrus americanus (L.) Morrone] is a staple food for more than 90 million farmers in arid and semi-arid regions of sub-Saharan Africa, India and South Asia. We report the ∼1.79 Gb draft whole genome sequence of reference genotype Tift 23DB-P1-P5, which contains an estimated 38,579 genes. We highlight the substantial enrichment for wax biosynthesis genes, which may contribute to heat and drought tolerance in this crop. We resequenced and analyzed 994 pearl millet lines, enabling insights into population structure, genetic diversity and domestication. We use these resequencing data to establish marker trait associations for genomic selection, to define heterotic pools, and to predict hybrid performance. We believe that these resources should empower researchers and breeders to improve this important staple crop.
珍珠粟[美洲狼尾草（L.）莫罗内]是撒哈拉以南非洲、印度和南亚干旱和半干旱地区9000多万农民的主食。我们报告了参考基因型Tift 23DB-P1-P5约1.79Gb的全基因组草图序列，其中估计包含38579个基因。我们强调了蜡生物合成基因的大量富集，这可能有助于该作物的耐热和耐旱性。我们对994份珍珠粟品系进行了重测序和分析，从而深入了解群体结构、遗传多样性和驯化情况。我们利用这些重测序数据建立标记-性状关联用于基因组选择，定义杂种优势群，并预测杂交表现。我们相信，这些资源将使研究人员和育种者有能力改良这种重要的主食作物。
