Rice ARGONAUTE 2 (AGO2) binds the small RNA miR167g-3p and facilitates its repression of the target gene SNAP32 during rice ragged stunt virus infection. AGO2 also associates with virus-derived small RNAs. miR167g-3p accumulation and SNAP32 suppression correspond with reduced viral levels, whereas decreased miR167g-3p or elevated SNAP32 increases susceptibility.

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).

Diagram of calcium signaling in rice. Osmotic stress affects the cell, which undergoes a wave of increased cytoplasmic calcium. This leads to osmotic adjustment in the cell (depicted as a green rectangle). In wild-type, the osmotic adjustment is strong (thick black arrow) leading to drought tolerance, depicted as a black arrow pointing to a healthy plant. In the ccx2 mutants, which lack the cation/calcium exchange protein, the osmotic adjustment is weak (thin red arrow), leading to drought sensitivity, depicted as a red arrow pointing to a yellow, unhealthy plant.
