天天中彩票摘要：Pre-harvest sprouting (PHS), adversely affects yield and grain quality in cereal crops worldwide. Here, a systematic analysis of wheat PHS was conducted by using 680 worldwide wheat accessions by the genome-wide association study (GWAS). A total 102 PHS-controlled loci were identified. A causal gene of a novel locus, namely TaPI4K-2A, was identified as a key regulator of wheat PHS.
穗发芽（PHS）是全世界范围内严重会影响谷物产量和品质的有害农艺性状。本研究利用680份来自世界各地的具有广泛遗传多样性的小麦种质为材料，采用全基因组关联分析（GWAS）系统研究了小麦PHS性状，总共鉴定到了102个与PHS相关的数量性状基因座（QTL），并从其中一个新的QTL位点中挖掘到了一个新的小麦PHS调控基因 TaPI4K-2A ，为通过分子育种等手段培育穗发芽抗性小麦品种提供了新靶标。
