摘　　要：同源异型盒基因KNOX1(class I KNOTTED-like homeobox)广泛存在于植物中,具备调控和维持茎顶端分生组织活性的功能。近年来研究发现,KNOX1基因家族参与植物激素调控和各个器官的形态建成,尤其对植物花和叶的发育有着重要作用。本文介绍了KNOX1的表达模式,与植物激素的调控作用,在花和叶形态建成中的功能,并综述了拟南芥中KNOX1的相互作用因子及其功能,为进一步阐明KNOX1在植物发育中的分子机制提供参考。最后展望了未来KNOX1的研究方向及发展趋势。KNOX1(class I KNOTTED-like homeobox)genes are crucial for regulation and maintenance of shoot apical meristem,which are widely existed in plants.In recent years,KNOX1 genes had been found play an important role in hormone regulation and organ morphogenesis,especially for flower and leaf in plant.We introduced the expression pattern of KNOX1,function of KNOX1 genes in hormone regulation and morphogenesis of flower and leaf organ.Then,we reviewed the interaction factors of KNOX1,which provided reference for further elucidating the molecular mechanism of KNOX1 in the plant development.In the end,we predicted the research direction and development trend of KNOX1 in the future.
