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 demonstrates that Magnesium Iron-layered double hydroxide (MgFe-LDH) nanocarriers effectively protect and deliver fungal effector dsRNA to pea leaves, enabling sustained gene silencing of Erysiphe pisi and providing enhanced local and systemic powdery mildew resistance for up to 15 days. The LDH formulation exhibits strong leaf adherence, biocompatibility, RNase protection, and rapid uptake into plant cells and fungal haustoria, outperforming dsRNA or LDH alone.

The study demonstrates that the RNAi factor AGO5, expressed in Arabidopsis thaliana shoot apical meristem stem cells and germline, markedly reduces vertical transmission of Turnip yellow mosaic virus (TYMV). Using controlled pollination with ago5 knock‑out and cell type‑specific rescue lines, the authors show that AGO5 functions in pollen and sperm cells to block virus passage, and that targeted activation of antiviral RNAi in sperm further lowers transmission rates.

The study evaluated a transgenic soybean line (VPZ-34A) expressing Arabidopsis VDE, PsbS, and ZEP for combined improvements in light‑use efficiency and carbon assimilation under ambient and elevated CO2 in a FACE experiment. While VPZ‑34A showed enhanced maximum quantum efficiency of PSII under fluctuating light, it did not increase carbon assimilation efficiency or yield, and transcriptome analysis revealed limited gene expression changes. The results suggest that VPZ‑mediated photosynthetic gains are insufficient to boost productivity under elevated CO2.

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 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 identified lineage-specific long non‑coding RNAs (lncRNAs) from the aphid‑specific Ya gene family in Rhopalosiphum maidis and R. padi, demonstrating that these Ya lncRNAs are secreted into maize, remain stable, and move systemically. RNA interference of Ya genes reduced aphid fecundity, while ectopic expression of Ya lncRNAs in maize enhanced aphid colonization, indicating that Ya lncRNAs act as cross‑kingdom effectors that influence aphid virulence.

The study characterizes insertion mutants of the Arabidopsis thaliana CKL12 kinase, revealing its role in hypocotyl and primary root growth and indicating that the 3' end of its transcript is crucial for function. Evidence suggests CKL12 is transcriptionally regulated by brassinosteroid signaling, as its promoter binds BR-related transcription factors and their RNAi-mediated knock‑down reduces CKL12 expression, placing CKL12 downstream of BR signaling in seedling development.

The study identifies the brown planthopper salivary protein NlAnnexin-like5 (NlANX5) as a key virulence effector that disrupts rice annexin (OsANN) function, leading to altered calcium signaling and reduced plant resistance. RNAi silencing of NlANX5 impairs BPH feeding, while transgenic rice overexpressing OsANN2/OsANN8 or NlANX5 restores resistance, demonstrating an anti‑virulence breeding strategy for rice.

The study presents a high-quality genome assembly for the nickel hyperaccumulator Noccaea caerulescens and uses it as a reference for comparative transcriptomic analyses across different N. caerulescens accessions and the non‑accumulating relative Microthlaspi perfoliatum. It identifies a limited set of metal transporters (NcHMA3, NcHMA4, NcIREG2, and NcIRT1) whose elevated expression correlates with hyperaccumulation, and demonstrates that frameshift mutations in NcIRT1 can abolish the trait, indicating an ancient, transporter‑driven origin of nickel hyperaccumulation.
