摘要

营养信号和胁迫反应的协调对植物的生存至关重要。最近，Ma等人报道硝酸盐转运体nrt11 b结合脱落酸（ABA）并调节SPX4-NLP4模块激活ABA应答基因。这代表了一种潜在的跨膜ABA感知机制，补充了典型的PYR-蛋白磷酸酶2C (PP2C)- snrk2途径。

Breaking the barrier: NRT1.1B bridges ABA signaling across membranes.

Coordination of nutrient signals and stress responses is essential for plant survival. Recently, Ma et al. reported that the nitrate transporter NRT1.1B binds abscisic acid (ABA) and regulates the SPX4-NLP4 module to activate ABA-responsive genes. This represents a potential transmembrane ABA perception mechanism that complements the canonical PYR- protein phosphatase type 2C (PP2C)-SnRK2 pathway.
