Schematic illustration of NRT1.1B-SPX4-NLP4 or NLP3 response patterns in six different states. States I–IV correspond to plants exposed to constant low-nitrate (LN) or high-nitrate (HN) conditions, as discussed in Ma et al. (2025). States I and II depict a stress-free condition, while states III and IV depict a stress condition, in which abscisic acid (ABA) molecules (red circles) bind to NRT1.1B exclusively under constant LN (Figure 1 State III). Under constant HN conditions, instead of ABA molecules, nitrate ions bind to NRT1.1B, and nitrate is transported from the outside to the inside of the cell (Figure 1 State IV). Abscisic acid molecules are substituted by nitrate. As a reference, the transient application of nitrate ions (green circles) is also included for states V and VI, as discussed in Hu et al. (2019) (note that NLP3 is used here instead of NLP4).
