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 identifies the AP2/ERF transcription factor GEMMIFER (MpGMFR) as essential for asexual reproduction in the liverwort Marchantia polymorpha, showing that loss of MpGMFR via genome editing or amiRNA abolishes gemma and gemma cup formation, while dexamethasone‑induced activation triggers their development. Transient strong activation of MpGMFR initiates gemma initial cells at the meristem, which mature into functional gemmae, indicating MpGMFR is both necessary and sufficient for meristem‑derived asexual propagule formation.

A field trial of ten grapevine rootstock genotypes grafted to two scion varieties revealed that vine compartment (berry vs. root) primarily determines elemental composition, while rootstock genotype has modest effects. The rhizosphere microbiome was largely conserved across genotypes, but taxa such as Streptomyces and Mesorhizobium showed negative correlations with a mineral profile dominated by molybdenum, cadmium, potassium, and iron, indicating specific microbe‑element associations.

The study generated a high-quality, phased diploid reference genome for the grapevine cultivar Pinot noir and combined it with Oxford Nanopore sequencing of 23 clones to map genome-wide genetic and epigenetic variation. While somatic SNPs and structural variants are rare and depleted from coding regions, extensive CG methylation differences were found within gene bodies and accurately recapitulated clonal phylogenies, indicating stable, mitotically inherited epialleles that record propagation history.

The study generated a dataset of 420 sgRNAs targeting promoters, exons, and introns of 137 tomato genes in protoplasts, linking editing efficiency to chromatin accessibility, genomic context, and sequence features. Open chromatin sites showed higher editing rates, while transcriptional activity had little effect, and a subset of guides produced near‑complete editing with microhomology‑mediated deletions. Human‑trained prediction models performed poorly, highlighting the need for plant‑specific guide design tools.

A common garden study of 46 Vitis vinifera cultivars revealed that cultivar-specific water-use traits, rather than xylem anatomy, predict susceptibility to esca disease. Symptomatic vines showed reduced leaf gas exchange, starch storage, and theoretical hydraulic conductivity, while highly susceptible genotypes accumulated more glycosylated flavonoids and terpenes, suggesting a role for xylem‑transported defence metabolites in disease onset.

The study identifies MtFTb1 and MtFTb2 as essential, redundant regulators of long‑day flowering in the legume Medicago truncatula, demonstrating that they are required for up‑regulating MtFTa1 under vernalised long‑day conditions. Using CRISPR/Cas9‑generated single and double mutants, the authors show that double mutants are specifically delayed in flowering under long days while retaining vernalization responsiveness, and transcriptomic analyses reveal that MtFTb1/2 activate MADS‑box genes and other flowering regulators.

The study identified 12 SABATH methyltransferase genes in the liverwort Marchantia polymorpha and demonstrated that MpSABATH2 is crucial for normal thallus growth and gemma cup formation. Loss‑of‑function mutants displayed developmental phenotypes reminiscent of far‑red light responses, which were linked to gibberellin metabolism and could be partially rescued by inhibiting GA biosynthesis or supplying the GA precursor ent‑kaurenoic acid. These findings suggest that SABATH enzymes independently evolved regulatory roles in land‑plant development.

In a common‑garden study of 23 Vitis vinifera cultivars, the authors linked higher white‑rot necrosis and elevated hemicellulose coupled with reduced extractives to increased susceptibility to Esca disease. Glycosylated phenylpropanoids accumulated in symptomatic vines, while the composition of healthy‑wood endophytic microbial communities remained unchanged across cultivars, indicating that wood degradability and metabolic response drive susceptibility more than microbial factors.

The study demonstrates that carbon availability promotes gemma cup formation in Marchantia polymorpha by activating cytokinin signaling, which up‑regulates the transcription factors MpGCAM1 and MpSTG. Pharmacological and genetic manipulations showed that cytokinin accumulation in response to sucrose and high light is sufficient to overcome low‑sucrose repression, and that this pathway operates independently of KAI2A‑MAX2 mediated karrikin signaling. The findings suggest a conserved carbon‑cytokinin interaction governing developmental plasticity across land plants.
