The study investigates the role of the Arabidopsis transcription factor AtMYB93 in sulfur (S) signaling and root development, revealing that AtMYB93 mutants exhibit altered expression of S transport and metabolism genes and increased shoot S levels, while tomato plants overexpressing SlMYB93 show reduced shoot S. Transcriptomic profiling, elemental analysis, and promoter activity assays indicate that AtMYB93 contributes to root responses to S deprivation, though functional redundancy masks clear phenotypic effects on lateral and adventitious root formation.

The study links circadian rhythm traits in Arabidopsis seedlings to flowering time synchronization across latitudes by mapping QTLs in recombinant inbred lines derived from African and European lineages. Two QTLs containing KH-domain RNA‑binding proteins (KH17, KH29) affect splicing of key flowering regulators (MAF2, MAF3), creating chimeric transcripts that may accelerate proteome evolution and decouple mean flowering time from its synchronization, offering a predictive tool for breeding climate‑resilient crops.

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.
