The establishment of symbiotic nitrogen fixation requires the coordination of both nodule development and infection events. Despite the evolution of a variety of anatomical structures, nodule organs serve a common purpose in establishing a localized area that facilitates efficient nitrogen fixation. As in all plant developmental processes, the establishment of a new nodule organ is regulated by plant hormones. During nodule initiation, regulation of plant hormone signaling is one of the major targets of symbiotic signaling. We review the role of major developmental hormones in the initiation of the nodule organ and argue that the manipulation of plant hormones is a key requirement for engineering nitrogen fixation in non-legumes as the basis for improved food security and sustainability.

无激素无家:植物激素如何控制豆类根瘤器官发生

共生固氮的建立需要结核发展和感染事件的协调。尽管存在各种解剖结构的演变,但结节器官的共同目的是建立一个促进有效固氮的局部区域。与所有植物发育过程一样,新根瘤器官的建立受植物激素的调控。在根瘤发生过程中,植物激素信号的调节是共生信号的主要目标之一。我们回顾了主要发育激素在根瘤器官起始中的作用,并认为植物激素的操纵是非豆科植物固氮工程的关键要求,是改善粮食安全和可持续性的基础。
