摘要/Abstract

摘要：

小麦开花时间是决定产量潜力和环境适应性的关键农艺性状。本研究基于前期报道的一个小麦开花时间主效QTL，聚焦其候选区间附近的生物钟基因TaPRR95-A开展功能鉴定。结果表明，TaPRR95-A在长日照条件下可显著促进开花（提前4.38–6.10天），并上调成花素基因TaFT1的表达。分子机制研究发现，TaPRR95-A通过与光周期核心因子TaCOL16-D相互作用，间接激活TaFT1的表达，为理解小麦开花时间调控网络提供了新的见解。此外，本研究鉴定到一个关键自然单倍型TaPRR95-A^HapII，该单倍型编码区携带12 bp缺失，导致蛋白截短4个氨基酸，与早花性状及增产（450.38–597.54 kg·hm^-²）显著相关。基于该多态性位点开发的功能分子标记，可用于早熟高产小麦品种的选育。本研究不仅阐明了开花调控的新机制，还为培育气候适应性小麦品种提供了重要的遗传工具。
