花粉育性是水稻生殖发育中的重要性状，直接影响水稻的产量。本研究鉴定到一个包含Glyco＿32核心结构域的糖苷水解酶编码基因OsINV3。通过实时定量PCR对OsINV3的时空表达模式分析发现，该基因在穗发育各阶段均有表达且在幼穗分化第6期具有较高的表达水平。通过亚细胞定位分析，发现OsINV3定位于细胞质。利用CRISPR/Cas9技术获得了粳稻9522和籼稻五山丝苗背景下的功能缺失突变体952201590-1和952201590-2、WSSM01590-1和WSSM01590-2。通过对表型分析及农艺性状统计发现，2种不同背景的突变体材料均表现为株高矮化、花粉育性下降、结实率降低。进一步分析发现，不同背景的突变材料，对育性下降的程...

Pollen fertility is an important character in rice reproduction and development,which directly affects rice yield.A glycoside hydrolase-encoding gene OsINV3 containing Glyco_32 core domain was identified.Temporal and spatial expression pattern analysis of OsINV3 by real-time quantitative PCR showed that OsINV3 gene was expressed at all stages of panicle development and had a high expression level in the 6th stage of young panicle differentiation.Subcellular localization analysis showed that OsINV3 was localized in cytoplasm.The non-functional mutants 952201590-1 and 952201590-2,WSSM01590-1 and...
