The authors used a bottom‑up thermodynamic modelling framework to investigate how plants decode calcium signals, starting from Ca2+ binding to EF‑hand proteins and extending to higher‑order decoding modules. They identified six universal Ca2+-decoding modules that can explain variations in calcium sensitivity among kinases and provide a theoretical basis for interpreting calcium signal amplitude and frequency in plant cells.

A diverse rice germplasm panel was screened for cold tolerance at seedling and reproductive stages using artificial cold-water tanks, natural field conditions, and controlled cold facilities, with performance evaluated via quantitative and qualitative traits. Several genotypes displayed stage-specific or combined tolerance, while others were consistently vulnerable, and PCA indicated overlapping yet distinct physiological mechanisms across environments, supporting the existence of stage-specific QTLs for cold resistance.

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.

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 assessed ten fruit morphological traits of ancient Cinnamomum camphora across 45 counties in Jiangxi Province, finding substantial phenotypic variation with 80.1% of variation among provenances. Using nested ANOVA, Pearson correlation, PCA, and cluster analysis, the authors linked trait differences to latitude, longitude, and climate, highlighting traits useful for germplasm selection and breeding.
