The study performed transcriptome profiling of Cryptomeria japonica individuals from different geographic origins grown in three common gardens across Japan, assembling 77,212 transcripts guided by the species' genome. Using SNP-based genetic clustering and weighted gene co‑expression network analysis, they identified gene modules whose expression correlated with genetic differentiation, revealing that defense‑related genes are up‑regulated in Pacific‑side populations while terpenoid metabolism genes are higher in Sea‑of‑Japan populations, indicating local adaptation via regulatory changes.

The study demonstrates that the GIGANTEA (GI) protein is a core component of the wheat circadian clock, required for robust oscillations in chlorophyll fluorescence and clock gene expression. Loss of functional GI leads to delayed heading under both long and short photoperiods, indicating a photoperiod‑1‑dependent pathway distinct from Arabidopsis. These findings provide insight into photoperiodic regulation of flowering in wheat, informing breeding strategies for high‑yield cultivars.

The study examined transcriptomic responses of the tropical seagrass Halophila stipulacea from a pristine and an impacted site under single and combined thermal and excess nutrient stress in mesocosms. Combined stress caused greater gene reprogramming than individual stresses, with thermal effects dominating and the impacted population showing reduced plasticity but higher resilience. Core stress‑response genes were identified as potential early field indicators of environmental stress.
