摘　　要：作为调控植物生长发育的5种重要激素之一,赤霉素参与调节小麦的种子萌发、株高建成、幼穗发育及胁迫响应等生理过程,赤霉素信号途径的合理利用对提升小麦的产量做出了十分积极的贡献。主要综述了近五年来赤霉素生物合成关键基因的克隆、对重要农艺性状的调控以及赤霉素信号传导途径中重要基因的功能等方面在小麦中的研究进展,以期为更好的利用赤霉素及其信号途径进一步提升小麦的产量及抗性提供参考。As one of the five important plant hormones,gibberellins regulate many physiological processes in wheat including the seed germination,plant height establishment,spike development and stress responses. The manipulation of GA signaling pathway promoted the increase of wheat yield. We reviewed the research progress in wheat focusing on the GA biosynthesis,agronomic traits regulation by GA,and functional studies of key genes in GA signaling pathway in the past five years,which was expected to provide reference for better utilization of the GA pathway to further increasing of the wheat yield and resistance.
