驯化对栽培禾本科植物花序和株高性状的形成起着重要作用。利用QTL的荟萃分析，在502个不同的高粱种质系统发育分析，GWAS在高粱协会面板（n = 354）和比较数据，我们提供了深入了解高粱和水稻驯化性状的遗传基础。对高粱6个花序形态相关性状和6个株高相关性状进行了全基因组关联研究（GWAS），比较了GWAS和QTL定位的基因组区域。在寻找选择的签名，我们确定基因组区域，可能有助于高粱驯化有关株高，开花时间和果皮颜色。跨类群的比较研究表明，高粱和水稻芒的存在和果皮颜色，似乎并不反映相应的单基因，但可能表明共同调控的基因簇功能保守的“热点”。我们还揭示了同源异型区保留相似的功能，植物高度和开花时间，因为基因组复制估计70万年前或更长的时间在一个共同的祖先谷物。在大多数这样的同源QTL对中，只有一个QTL区间在现代高粱中表现出强的选择信号。QTL、GWAS和比较数据之间的交叉促进了对高粱花序和株高组成的遗传决定因素的认识，并为高粱和水稻之间的比较增加了新的维度。本文的在线版本（doi：10.1186/s12870-015-0477-6）包含补充材料，可供授权用户使用。
Domestication has played an important role in shaping characteristics of the inflorescence and plant height in cultivated cereals. Taking advantage of meta-analysis of QTLs, phylogenetic analyses in 502 diverse sorghum accessions, GWAS in a sorghum association panel (n = 354) and comparative data, we provide insight into the genetic basis of the domestication traits in sorghum and rice. We performed genome-wide association studies (GWAS) on 6 traits related to inflorescence morphology and 6 traits related to plant height in sorghum, comparing the genomic regions implicated in these traits by GWAS and QTL mapping, respectively. In a search for signatures of selection, we identify genomic regions that may contribute to sorghum domestication regarding plant height, flowering time and pericarp color. Comparative studies across taxa show functionally conserved ‘hotspots’ in sorghum and rice for awn presence and pericarp color that do not appear to reflect corresponding single genes but may indicate co-regulated clusters of genes. We also reveal homoeologous regions retaining similar functions for plant height and flowering time since genome duplication an estimated 70 million years ago or more in a common ancestor of cereals. In most such homoeologous QTL pairs, only one QTL interval exhibits strong selection signals in modern sorghum. Intersections among QTL, GWAS and comparative data advance knowledge of genetic determinants of inflorescence and plant height components in sorghum, and add new dimensions to comparisons between sorghum and rice.
