The authors performed time‑resolved RNA‑seq on three‑week‑old Arabidopsis thaliana Col‑0 rosettes sampled every two hours over a 24‑hour light/dark cycle and integrated the data with publicly available single‑cell transcriptomes. They found that intermediate regulators—kinases, E3 ligases, and transcription factors—are low‑abundance but display extensive temporal and spatial expression variation, highlighting the importance of sampling time‑of‑day and cellular resolution for studies of metabolism and stress responses.

A large-scale proteomic study in Arabidopsis thaliana identified over 32,000 isoform-specific peptides, confirming that alternative splicing, particularly intron retention, produces translated protein isoforms. Integrated proteogenomic analysis, SUPPA classification, and AlphaFold modeling revealed structural impacts and a non-linear regulation of transcript and protein abundance, with mutant phenotypes linking splicing to growth, chlorophyll content, and anthocyanin accumulation.

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 investigated metabolic responses of kale (Brassica oleracea) grown under simulated microgravity using a 2-D clinostat versus normal gravity conditions. LC‑MS data were analyzed with multivariate tools such as PCA and volcano plots to identify gravity‑related metabolic adaptations and potential molecular markers for spaceflight crop health.

The study reveals that whole‑seedling transcriptomic analyses of Arabidopsis thermomorphogenesis are highly variable and often mask organ‑specific responses, with nearly 70% of differentially expressed genes in whole seedlings not detected in any dissected organ. By directly comparing RNA‑seq from whole seedlings and individual organs (root, hypocotyl, cotyledon) and supporting the findings with proteomics, the authors demonstrate that pooling tissues confounds gene‑regulation insights and call for organ‑level approaches in future warm‑temperature research.

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.

The study characterized the virome of Tamarillo (Solanum betaceum) across eight locations in Narino, Colombia, revealing up to four virus species from the Torradovirus, Potyvirus, and Polerovirus genera, including the first report of a torradovirus in tamarillo. A novel isolate of potato virus Y‑Tamarillo (PVY‑Tam) with unique P3N‑PIPO protein truncations was identified, suggesting host‑specific adaptation and informing future diagnostic and control strategies.

The study used RNA‑seq to compare early transcriptional responses to acute heat and cold stress in cultivated cranberry (Vaccinium macrocarpon) and its F1 hybrids with the cold‑adapted wild relative V. oxycoccos. Cold stress triggered differential expression in pathways such as photosynthesis, ribosomes, defense, and hormone signaling, with some hybrids showing transiently elevated cold‑responsive expression, suggesting potential cold‑tolerance introgression. The results highlight the utility of wild germplasm for breeding temperature‑resilient cranberries.

The study identifies the transcription factor MdBRC1 as a key inhibitor of bud growth during the ecodormancy phase in apple (Malus domestica), directly regulating dormancy‑associated genes and interacting with the flowering promoter MdFT2 to modulate bud break. Comparative transcriptomic analysis and gain‑of‑function experiments in poplar demonstrate that MdFT2 physically binds MdBRC1, attenuating its repressive activity and acting as a molecular switch for the transition to active growth.

The study investigated the molecular basis of quantitative resistance to black spot disease in a Rosa wichurana × Rosa chinensis F1 population, identifying two major QTLs (B3 on LG3 and B5 on LG5). RNA‑seq of inoculated and control leaf samples at 0, 3, and 5 days post‑inoculation revealed extensive transcriptional reprogramming, with QTL B3 triggering classic defense pathways and QTL B5 showing a limited, distinct response. These findings highlight complex, QTL‑specific regulation underlying durable black‑spot resistance in roses.
