许多植物通过丛枝菌根真菌获取营养，而豆科植物也通过固氮根瘤菌。这两种关联都依赖于共生信号，在这里，我们发现谷物可以感知脂壳寡糖（LCOs）激活共生信号，令人惊讶的是，其中包括由固氮细菌产生的Nod因子。然而，豆类显示出对特殊修饰的lco的严格感知，这在谷物中是不存在的。植物的LCO感知是通过调控结瘤信号通路（NSP）1和NSP2的转录来激活营养饥饿的。这些转录因子诱导LCO受体的表达，并通过控制独行孤内酯生物合成和卡瑞金样受体DWARF14-LIKE发挥作用。我们得出结论，LCO的产生和感知是由营养饥饿协调调节的，以促进与菌根真菌的接触。我们的工作对利用菌根和根瘤菌的联系促进谷物的可持续生产力具有启示意义。豆科植物对脂壳寡糖（LCO）的感知是与固氮细菌建立共生关系所必需的。本研究表明，营养饥饿可以激活谷物中的LCO感知，促进与丛枝菌根真菌的共生关系。
Many plants associate with arbuscular mycorrhizal fungi for nutrient acquisition, while legumes also associate with nitrogen-fixing rhizobial bacteria. Both associations rely on symbiosis signaling and here we show that cereals can perceive lipochitooligosaccharides (LCOs) for activation of symbiosis signaling, surprisingly including Nod factors produced by nitrogen-fixing bacteria. However, legumes show stringent perception of specifically decorated LCOs, that is absent in cereals. LCO perception in plants is activated by nutrient starvation, through transcriptional regulation of Nodulation Signaling Pathway (NSP)1 and NSP2. These transcription factors induce expression of an LCO receptor and act through the control of strigolactone biosynthesis and the karrikin-like receptor DWARF14-LIKE. We conclude that LCO production and perception is coordinately regulated by nutrient starvation to promote engagement with mycorrhizal fungi. Our work has implications for the use of both mycorrhizal and rhizobial associations for sustainable productivity in cereals. Lipochitooligosaccharide (LCO) perception by legumes is required to establish symbiotic relationships with nitrogen fixing bacteria. Here the authors show that nutrient starvation can activate LCO perception in cereals to promote symbiotic association with arbuscular mycorrhizal fungi.
