摘　　要：【目的】认识小麦穗发育调控相关基因及调控网络,为穗部性状遗传改良和育种利用奠定基础。【方法】通过查阅国内外小麦穗发育相关文献和基因的研究动态,对小麦穗发育过程、穗部调控相关基因和穗部相关的重要QTL等方面进展进行总结与分析。【结果】小麦的穗部性状直接与产量相关,其穗部发育一直是育种家和分子生物学家研究的热点。基于水稻和玉米的研究进展,以及测序技术和分子生物技术的发展,许多研究已经证明一些基因在小麦的穗发育过程中发挥关键作用,影响穗部性状,小麦穗发育的调控途径也逐渐被发现。【结论】小麦穗发育研究与禾本科模式作物水稻相比较为缓慢,但随着测序技术和转基因技术的发展,将大大加快穗型调控基因的克隆和功能分析,小麦穗部研究正迎来春天。【Objective】To understand key genes and their regulation pathways associated with spike development in wheat,and thus lay a foundation for genetic improvement and breeding utilization of spike traits,we here reported on progress on wheat spike development-related genes.【Method】The research progress of wheat spike development process,related genes and important quantitative trait loci(QTL)were summarized and analyzed by consulting the relevant literature.【Result】Spike is an important agro⁃nomic trait which directly determines the yield.Spike development of wheat has always been the focus of research by breeders and molecular biologists.Benefiting from the research progress in rice and maize,as well as the development of sequencing technology and molecular biotechnology,numerous studies have re⁃ported that a few of genes play a key role in wheat spike development.Regulatory pathways associated with wheat spike development have been gradually identified.【Conclusion】Compared with rice,the study on spike development in wheat is relatively slow.But with the development of sequencing technol⁃ogy and transgenic technology,the cloning of spike regulation-related genes will be greatly accelerated.
