被子植物整合了多种内源和环境信号来控制花的发育，从而确保繁殖成功。本文报道了蒺藜苜蓿花发育的新调控因子AGTFL的鉴定。AGTFL基因突变导致心皮和雄蕊转化为大量的萼片和花瓣，并改变了初生花序的特性。AGTFL编码一种核定位蛋白，含有一个推定的Myb/SANT样DNA结合结构域和一个PKC激酶结构域。分子和遗传分析表明，AGTFL调节MtAGs和MtTFL 1的转录，以控制花器官的身份和花序的发育。
Angiosperms integrate a multitude of endogenous and environmental signals to control floral development, thereby ensuring reproductive success. Here, we report the identification ofAGAMOUS AND TERMINAL FLOWER(AGTFL), a novel regulator of floral development inMedicago truncatula. Mutation of AGTFL led to the transformation of carpels and stamens into numerous sepals and petals and altered primary inflorescence identity.AGTFLencodes a nucleus‐localized protein containing a putative Myb/SANT‐like DNA‐binding domain and a PKc kinase domain. Molecular and genetic analyses revealed that AGTFL regulates the transcription ofMtAGs andMtTFL1to control floral organ identity and inflorescence development.
