NNC1与豆科模式植物百脉根中的NODULE INCEPTION(NIN)在大豆中的直向同源物GmNINa互作,并抑制GmNINa对GmRIC1和GmRIC2的转录激活,实现对结瘤自调控信号的精密调控。本研究还发现GmNINa可以转录激活miR172c,而NNC1会反馈抑制miR172c表达。此外,GmNI...
(NNC1),leading to the activation of the AON pathway.NNC1 interacts with GmNINa,the soybean ortholog of Lotus NODULE INCEPTION(NIN),and hampers its transcriptional activation o i G m RICI and GmRIC2.Importantly,GmNINa acts as a transcriptional activator of miR172c.Intriguingly,NNC1 can ...
we show that the target gene NNC1 of miR172 c was downregulated by salt stress.The transgenic roots overexpressing or knocking down NNC1 expression also exhibits the altered root sensitivity to salt stress.Our results reveal the crucial role of miR172c-NNC1 mod...
