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 investigates how miR394 influences flowering time in Arabidopsis thaliana by combining transcriptomic profiling of mir394a mir394b double mutants with histological analysis of reporter lines. Bioinformatic analysis identified a novel lncRNA overlapping MIR394B (named MIRAST), and differential promoter activity of MIR394A and MIR394B suggests miR394 fine‑tunes flower development through transcription factor and chromatin remodeler regulation.

The study examined interspecific and intraspecific drought responses of Populus fremontii, P. angustifolia, and their hybrids using leaf-level visible‑shortwave infrared spectroscopy and canopy-level UAV thermal imaging. Spectral shifts revealed that hybrids showed the strongest drought reaction, while local adaptation influenced the magnitude and direction of spectral changes, demonstrating convergence under stress. These findings highlight remote sensing as a powerful tool to detect ecological and evolutionary drought responses across scales.
