The study reveals that REMORIN protein evolution is primarily driven by diversification of their conserved C-terminal domain, defining four major clades. Structural bioinformatics predicts a common membrane‑binding interface with diverse curvatures and lengths, and suggests that some REMs can form C‑terminal‑mediated oligomers, adding complexity to membrane organization.

The complete chloroplast genome of the endemic fruit species Dillenia philippinensis was sequenced, assembled, and annotated, revealing a 161,591‑bp quadripartite structure with 113 unique genes. Comparative analyses identified simple sequence repeats, codon usage patterns, and phylogenetic placement close to D. suffroticosa, providing a genomic resource for future breeding and conservation efforts.

The study integrates multi-omics data from six Sorghum bicolor accessions under field drought to link RNA covalent modifications (RCMs) with photosynthetic performance, identifying the enzyme SbDUS2 that produces dihydrouridine (DHU) on transcripts. Loss‑of‑function dus2 mutants in Arabidopsis thaliana reveal that DHU deficiency leads to hyperstability of photosynthesis‑related mRNAs, impairing germination, development, and stress‑induced CO2 assimilation. The authors propose DHU as a post‑transcriptional mark that promotes rapid mRNA turnover during abiotic stress, enhancing plant resilience.

The authors compiled and standardized published data on Rubisco dark inhibition for 157 flowering plant species, categorizing them into four inhibition levels and analyzing phylogenetic trends. Their meta‑analysis reveals a complex, uneven distribution of inhibition across taxa, suggesting underlying chloroplast microenvironment drivers and providing a new resource for future photosynthesis improvement efforts.

A meta‑analysis of 73 studies on cucumber (Cucumis sativus) under elevated CO₂ (eCO₂) revealed that eCO₂ significantly increased net photosynthetic rate (+56.31%), biomass (+27.75%) and yield (+21.98%), while reducing stomatal conductance (‑36.07%) and transpiration (‑30.42%). The authors recommend maintaining eCO₂ levels between 800–1200 ppm together with higher light, temperature, optimal humidity, and adequate fertilization to optimise greenhouse cucumber production under climate‑change scenarios.

The study introduces an enhanced crosslinking mass spectrometry workflow that preserves native protein interactions within functional thylakoid membranes of Arabidopsis and spinach, while electron transport remains active. Mapping the obtained crosslinks to known structures validates complex integrity and reveals novel assemblies, facilitating in situ exploration of photosynthetic membrane protein networks.

The study examined how microclimatic factors influence leaf morphology and photosynthetic productivity in Arctostaphylos crustacea ssp. crustacea across two chaparral sites in California, finding that higher light and lower soil moisture increased leaf mass per area, leaf angle steepness, and photosynthetic rates. Linear mixed‑model analysis identified light level as the strongest predictor, with vapor pressure deficit, soil moisture, leaf temperature, and leaf angle also contributing, highlighting the role of combined microclimatic interactions in driving intraspecific trait variation.

Six new Viola species and two reinstated species from China were identified using field surveys, detailed morphological comparison, and phylogenetic analysis of ITS and GPI gene sequences, placing them in section Plagiostigma subsect. Diffusae. The GPI data offered higher resolution, indicating complex relationships possibly due to ancient hybridization or incomplete lineage sorting, thereby clarifying species boundaries and evolutionary patterns in Chinese Viola.

The study provides a comprehensive genome-wide catalog and single‑cell expression atlas of the carbonic anhydrase (CA) gene family in maize, identifying 18 CA genes across α, β, and γ subfamilies and detailing their structural and regulatory features. Phylogenetic, synteny, promoter motif, bulk tissue RNA‑seq, and single‑cell RNA‑seq analyses reveal distinct tissue and cell‑type specific expression patterns, highlighting β‑CAs as key players in C4 photosynthesis and γ‑CAs in ion/pH buffering, and propose cell‑type‑specific CA genes as targets for improving stress resilience.

The study presents a plant‑focused phylogenetic analysis of class B flavin‑dependent monooxygenases, identifying eight distinct families and revealing lineage‑specific diversification, especially in the NADPH‑binding domain. Using known FMOs as baits, they assembled flavin‑related proteins from key Viridiplantae lineages, performed domain architecture and motif analyses, and reclassified several families, providing a framework for future functional studies.
