Today's my last day at @slcuplants. On Monday I start a Royal Society University Research Fellowship @PPS_UoS, working on how #AbscisicAcid patterns regulate #Leaf #WaterRelations. I'm so grateful for the last 7 years in @xanderjones.bsky.social 's group who I'm really going to miss. (1/3)

Great work by Ma et al. (2025) on how NRT1.1B, a traditionally recognized #nitrate receptor, can directly perceive extracellular #AbscisicAcid (ABA) in a nitrate-antagonistic manner, thus enabling 🌾plants to integrate nutrient and abiotic stress cues (N level & drought)
www.cell.com/cell/fulltex...
Figure 7. NRT1.1B integrates compound environmental signals in plants. (M) A proposed model of nitrate-ABA coordinated responses mediated by NRT1.1B. Under low-nitrate conditions without ABA, NLP4 interacts with SPX4 and is sequestered in the cytoplasm. ABA perception enhances the NRT1.1B-SPX4 interaction, thereby promoting NLP4 release and translocation into the nucleus, and ultimately activates downstream ABA responses. Under high-nitrate conditions, nitrate competes with ABA for NRT1.1B binding, and NRT1.1B shifts to sense the nitrate signal.

This information tells us that in #soybean : phosphate starvation response starts with mild drought AND that the #phytohormone ABA (#abscisicacid) response is induced from a more severe drought. BUT the scientists wanted to know, do these finds apply to other 🌱 species?
