The study demonstrates that short‑term low phosphate treatment delays leaf senescence in rice by increasing photosynthetic pigments, enhancing antioxidant enzyme activities, and reducing oxidative damage, whereas high phosphate accelerates senescence. CRISPR/Cas9 editing of MIR827 to lower Pi levels also postpones senescence, while overexpression of MIR827 or MIR399, which raises Pi, speeds it up. Transcriptomic profiling reveals coordinated changes in senescence‑associated and metabolic pathways underlying the low‑phosphate response.

The study introduces a hybrid modeling framework that integrates a logistic ordinary differential equation with a Long Short-Term Memory neural network to form a Physics-Informed Neural Network (PINN) for predicting wheat plant height. Using only time and temperature as inputs, the PINN outperformed other longitudinal growth models, achieving the lowest average RMSE and reduced variability across multiple random initializations. The results suggest that embedding biological growth constraints within data‑driven models can substantially improve prediction accuracy for plant traits.

The study introduced charge-altering mutations into the N‑terminal region of Lhcb2 in Arabidopsis thaliana lacking native Lhcb2 to assess how intrinsic charge affects LHCII phosphorylation, state‑transition efficiency, and PSI‑LHCII complex formation. The R2E mutation drastically reduced Lhcb1/2 phosphorylation, impaired state transitions, and prevented PSI‑LHCII assembly, whereas the Q9E mutation had no measurable impact, and neither mutation altered thylakoid ultrastructure. Residual state transitions in the R2E line suggest that other Stn7 substrates can partially compensate for the loss of Lhcb2 phosphorylation.

The authors used a bottom‑up thermodynamic modelling framework to investigate how plants decode calcium signals, starting from Ca2+ binding to EF‑hand proteins and extending to higher‑order decoding modules. They identified six universal Ca2+-decoding modules that can explain variations in calcium sensitivity among kinases and provide a theoretical basis for interpreting calcium signal amplitude and frequency in plant cells.

Integrating physiological, transcriptomic, and cellular analyses, the study shows that olive fruit abscission zones undergo lignification, alkalization, and extensive cell‑wall remodeling during natural maturation and after ethephon treatment. A set of 733 FAZ‑specific genes, including β‑1,3‑glucanases, pectate lyases, and pH‑regulating transporters, were identified, and increased glucanase activity together with reduced plasmodesmata callose suggest enhanced intercellular communication facilitates organ detachment in this non‑climacteric fruit.

The study reveals that brassinosteroids activate phosphoenolpyruvate carboxykinase (PCK) by promoting dephosphorylation of conserved Ser-62 and Thr-66 residues, a process antagonized by the GSK3-like kinase BIN2. BR‑deficient Arabidopsis mutants exhibit reduced PCK activity, while phospho‑blocking mutations confer BR‑independent activation and enhanced seedling growth, and similar regulatory mechanisms are observed in maize and sorghum leaves.

The study generated deep proteome and phosphoproteome datasets from guard cell‑enriched tissue to examine how phosphorylation regulates stomatal movements. Comparative analysis revealed increased phosphorylation of endomembrane trafficking and vacuolar proteins in closed stomata, supporting a role for phospho‑regulated trafficking in stomatal dynamics.

The study demonstrates that limonene, a natural essential‑oil component, strongly inhibits Fusarium oxysporum, the causal agent of potato dry rot, by impairing colony growth, hyphal morphology, spore viability, membrane integrity, and transcription/translation processes, as well as disrupting ion homeostasis. Combined treatments reveal additive effects with mancozeb and synergistic effects with hymexazol, highlighting limonene's potential as an eco‑friendly bio‑fungicide for potato disease management.

The study identifies EPP1 as a fourth, conserved component of the ancestral common symbiosis pathway required for intracellular plant–microbe interactions, showing that its loss impairs arbuscular mycorrhizal colonization across diverse plant clades. EPP1 is phosphorylated by the plasma‑membrane receptor SYRMK, and this modification is essential for downstream activation of the nuclear kinase CCaMK, positioning EPP1 upstream in the signaling cascade.

The study demonstrates that ABI5‑Binding Proteins (AFPs) interact with multiple components of the core ABA signaling pathway and serve as substrates for SnRK2 kinases and PP2C phosphatases, linking them to MAP kinases and 14‑3‑3 proteins. Phosphorylation of AFP2, promoted by ABA, stabilizes the protein and influences its subcellular localization, thereby modulating its ability to inhibit ABA responses during seed germination.
