NRT1.1B acts as an abscisic acid receptor in integrating compound environmental cues for plantsNRT1.1B, a traditionally recognized nitrate receptor, can directly perceive the extracellular ABA signal to form a complex with the repressor protein SPX4, thereby releasing the SPX4-sequestered transcription factor NLP4 and initiating the ABA transcriptional response, while the competitive binding of nitrate and ABA to NRT1.1B generates a flexible ABA response to fluctuating nutrient conditions for compound environmental cues integration.NRT1.1B, a traditionally recognized nitrate receptor, can directly perceive the extracellular ABA signal to form a complex with the repressor protein SPX4, thereby releasing the SPX4-sequestered transcription factor NLP4 and initiating the ABA transcriptional response, while the competitive binding of nitrate and ABA to NRT1.1B generates a flexible ABA response to fluctuating nutrient conditions for compound environmental cues integration.Xiaojun Ma, Wei Wang, Jingyi Zhang, Zhimin Jiang, Chengyuan Xu, Wenjun Zhu, Bihai Shi, Wanling Yang, Haiwei Su, Xiaohan Wang, Da Chen, Yanfei Wang, Juntao Wang, Jingchi Wang, Xiujie Liu, Xiaotian Wang, Xiahe Huang, Wenjun Xie, Yanting Cai, Ke Xu, Peiyong Xin, Linchuan Liu, Peitao Lü, Yingchun Wang, Jinfang Chu, Xin Gong, Chengcai Chu, Bin Huhttps://www.cell.com/cell/fulltext/S0092-8674(25)00816-5?rss=yeshttp://www.cell.com/cell/inpress.rssCellCell RSS feed.Wireless News CampaignAugust 12, 2025
