In wheat, epigenetically regulated expression of FIP peptides upon pathogen challenge enables their perception by the receptor FIPR, thereby activating defence responses.

A rust effector interacts with a plasma membrane-anchored N-myristoylated protein TaMP to hijack and promote its relocalization from the plasma membrane to chloroplasts, increasing wheat susceptibility to rust fungus.

This Perspective reviews emerging nanocarriers for RNA delivery in agriculture and outlines future research directions, emphasizing that efficient delivery into plant cells, where viruses replicate, remains a key bottleneck for viral disease control.

The GmPEplus system achieves a prime editing (PE) efficiency of 81.3% in stably transformed soybean lines, while the Csy4-mediated multiplex PE system enables simultaneous multi-gene editing. These efficient and precise editing tools greatly facilitate genome editing for soybean breeding.

In competition, plant performance in conspecific and heterospecific soils is determined not only by negative or positive plant–soil feedbacks but also by neighbours inducing changes in the root microbiome that subsequently regulate plant growth.

In wheat, epigenetically regulated expression of FIP peptides upon pathogen challenge enables their perception by the receptor FIPR, thereby activating defence responses.

In Marchantia polymorpha, sperm-derived MpRALF1 is perceived by the MpFER–MpLLG receptor complex, triggering MpRBOHs-dependent NADPH oxidase activation and ROS production in sperm, which thereby promotes sperm motility.

Chloroplasts have key roles in plant immunity, but how external immune signals reach these organelles is unclear. We identified TaMP, a wheat protein that relocalizes from the plasma membrane to chloroplasts in response to pathogen infection, and found that a rust effector hijacks this process to promote TaGluTR degradation and increase wheat susceptibility to rust.

How senescing cells time their transition to the cell death programme is unclear. We show that, in Arabidopsis thaliana, senescing cells are genetically wired to dissipate their cytosolic arginine pool. This pool serves as a proxy for the efficiency of nitrogen remobilization, enabling precise timing between the remobilization and termination phases of senescence.

This work provides compelling evidence that the progression of leaf senescence is gated by the cytosolic arginine pool and that senescing cells are genetically wired to dissipate this pool. It is proposed that the cytosolic arginine pool serves as a proxy for nitrogen remobilization efficiency, thereby enabling precise timing of the remobilization and termination phases.
