Differential photoperiodic control of morning and evening expressed transcripts in tomato

Through high-resolution RNA-seq time-course analysis of tomato under varying photoperiods, this study reveals that morning-phased transcripts act as transcriptional sensors of day length to serve as zeitgeber references for evening transcripts, which measure photoperiod via coincidence with external cues to drive seasonal adaptation.

Streptomyces enrichment in roots during drought is uncoupled from plant benefit and is driven by host suppression of iron uptake and immunity

This study reveals that drought-induced suppression of plant immunity and iron uptake drives *Streptomyces* enrichment in roots across diverse soils and evolutionary lineages, yet the resulting plant benefits are uncoupled from this enrichment and instead depend on intra-genus antagonism among bacterial strains.

The MBW complex regulates volatiles in petunia flowers: EOBV interacts with AN1 to suppress biosynthesis of phenylpropenes

This study demonstrates that the EOBV protein functions as a component of the MBW complex to negatively regulate phenylpropene biosynthesis in petunia flowers while also mitigating heat-induced reductions in flower size, thereby revealing a molecular link between floral scent, pigmentation, and development.

Tissue- and Age-Specific Transcriptomic and Metabolomic Analysis Reveals Regulatory Mechanisms of Ginsenoside Biosynthesis in Panax notoginseng

By integrating targeted metabolomics and transcriptome profiling across multiple tissues and developmental stages, this study elucidates the spatiotemporal regulatory mechanisms of ginsenoside biosynthesis in *Panax notoginseng* and identifies four key transcription factors (AT3G12130, SPL9, MYB33, and SPL1) that coordinate the expression of biosynthetic enzymes to drive tissue-specific accumulation.

Molecular and phenotypic footprints of climate in native Arabidopsis thaliana

This study employs a landscape transcriptomics approach across multiple field sites and seasons to integrate phenotypic and transcriptomic data from over 3,000 native *Arabidopsis thaliana* plants, successfully linking climate fluctuations to gene expression and using machine learning to identify and validate both known and novel genetic regulators of temperature responses in natural environments.

CORNICHON HOMOLOG 5-dependent ER export of membrane cargoes in phosphate-starved Arabidopsis root as revealed by membrane proteomic analysis

This study identifies Arabidopsis CORNICHON HOMOLOG 5 (AtCNIH5) as a phosphate-starvation-induced endoplasmic reticulum cargo receptor that facilitates the export of specific membrane proteins, including phosphate transporters and various other transporters, thereby enhancing plant growth under low-phosphate conditions.

Two chromosome-level genome assemblies of Sarracenia reveal repeat-driven expansion and gene loss associated with carnivory.

This study presents chromosome-level genome assemblies of two *Sarracenia* species, revealing that the evolution of carnivory in this genus is driven primarily by repeat-driven genome expansion and widespread gene loss—particularly in photosynthesis and immunity pathways—rather than by extensive gene family expansion.
