摘要
株高是影响水稻产量稳定性的重要因素之一,水稻株高相关QTL的定位及候选基因的挖掘,有助于深入了解株高分子调控机制,进而为培育理想株型的水稻品种奠定基础。以油占8号及广西野生稻为亲本构建的285个CSSL群体为试验对象,结合NGS与BSA-seq等方法,利用SNP和InDel两种分子标记进行关联分析,对可能与株高相关的基因组区段进行定位。结果显示,Δ(SNP-index)分子标记在Chr.7和Chr.10中分别关联到3.205和1.311 Mb大小的候选基因组区域。Δ(InDel-index)标记关联到的基因组区域大小分别为2.848和1.292 Mb,且全部包含于Δ(SNP-index)关联到的区间内。结合GO、KEGG、Uniprot、eggNOG等数据库中的功能注释、高质量多态性位点筛选以及已有的株高相关转录组数据,最终关联到Chr.7中的5个候选基因,包括功能和机理已知的OsTCP21。RT-qPCR结果显示,OsTCP21在高株和矮株中的表达差异与已有研究结果相一致,LOC_Os07g05050和LOC_Os07g02850在高株中表达量较高,LOC_Os07g04220和LOC_Os07g02770在矮株中表达量较高。这5个候选基因在水稻株高性状的调控中起重要的作用,OsTCP21是一个关键调控基因。
