The study examined how prior light‑acclimation influences the fitness and rapid photoprotective reprogramming of Chlamydomonas during transitions between low and high diurnal light intensities. While high‑light‑acclimated cells struggled to grow and complete the cell cycle after shifting to low light, low‑light‑acclimated cells quickly remodeled thylakoid ultrastructure, enhanced photoprotective quenching, and altered photosystem protein levels, recovering chloroplast function within a single day. Transcriptomic and proteomic profiling revealed swift induction of stress‑response genes, indicating high flexibility in diurnal light acclimation.

The study demonstrates that the chromatin remodeler DDM1 is essential for biomass heterosis in Arabidopsis thaliana hybrids, as loss of DDM1 function leads to reduced rosette growth and extensive genotype‑specific transcriptomic and DNA methylation changes. Whole‑genome bisulfite sequencing revealed widespread hypomethylation in ddm1 mutants, while salicylic acid levels were found unrelated to heterosis, indicating that epigenetic divergence, rather than SA signaling, underpins hybrid vigor.

The study investigates the evolutionary shift from archegonial to embryo‑sac reproduction by analyzing transcriptomes of Ginkgo reproductive organs and related species. It reveals that the angiosperm pollen‑tube guidance module MYB98‑CRP‑ECS is active in mature Ginkgo archegonia and that, while egg cell transcription is conserved, changes in the fate of other female gametophyte cells drove the transition, providing a molecular framework for this major reproductive evolution.

The study applied a progressive, sublethal drought treatment to Arabidopsis thaliana, collecting time‑resolved phenotypic and transcriptomic data. Machine‑learning analysis revealed distinct drought stages driven by multiple overlapping transcriptional programs that intersect with plant aging, and identified high‑explanatory‑power transcripts as biomarkers rather than causal agents.

Salt stress strongly suppresses root growth in Festuca rubra while sparing shoot development. Transcriptome profiling identified over 68,000 differentially expressed genes, with up‑regulated genes enriched in methionine, melatonin, and suberin biosynthesis and down‑regulated genes involved in gibberellin, ABA, and sugar signaling, indicating extensive hormonal and metabolic reprogramming. Paradoxical regulation of gibberellin and ethylene pathways suggests a finely tuned balance between growth and stress responses.

The study examined how tomato (Solanum lycopersicum) plants respond hormonally to infection by Pseudomonas syringae pv. tomato DC3000 at two different temperatures, revealing temperature‑dependent expression of marker genes for salicylic acid, jasmonic acid, and abscisic acid pathways, while ethylene‑related genes remained unchanged. These results underscore the intricate interplay between host, pathogen, and environmental conditions in shaping plant defence.

The study examined how single and repeated mechanical disturbances (whole‑pot drops) affect leaf folding in Mimosa pudica, using chlorophyll fluorescence to track photosystem II efficiency and transcriptome profiling to identify responsive genes. A single drop mainly up‑regulated flavonoid biosynthesis genes, whereas multiple drops triggered broader biotic and abiotic stress pathways, indicating a shift in the plant’s gene regulatory network under repeated stress.

The study compared tissue‑specific transcriptomes of the Australian pitcher plant Cephalotus follicularis with existing data from the Asian pitcher plant Nepenthes gracilis to assess molecular convergence underlying their similar leaf morphologies. Both species showed overlapping gene expression in functionally equivalent tissues and shared transcriptional activation of amino‑acid metabolism and protein synthesis after feeding, while exhibiting distinct regulation of digestive enzyme genes and several cases of combined expression and protein‑sequence convergence in glandular tissues.

The study investigated whether expression of Dormancy-Associated MADS-BOX genes DAM3 and DAM4 inversely correlates with vegetative growth during semi-dormancy induction and breaking in cultivated strawberry. DAM3 and DAM4 expression showed negative correlations with leaf area and petiole length, with DAM4 particularly reflecting growth during dormancy breaking, while no cultivar-specific chill requirement or leaf-type differences were detected. These findings support DAM3 and DAM4 as regulators of semi‑dormancy in Fragaria × ananassa.

Kinase fusion proteins (KFPs) act as immune receptors conferring disease resistance in wheat and barley. The study identified an extended β‑finger motif, a Poaceae-specific feature that arose approximately 98 million years ago, present in functionally confirmed KFPs. These receptor genes are among the most highly expressed members of the KFP family, indicating that high transcript levels are linked to their resistance function.
