Chromatin accessibility profiling and transcriptomics of Marchantia polymorpha heat‑shock transcription factor (HSF) mutants reveal that HSFA1 governs the placement of cis‑regulatory elements for heat‑induced gene activation, a mechanism conserved across plants, mice, and humans. Integrated gene regulatory network modeling identifies MpWRKY10 and MpABI5B as indirect regulators linking phenylpropanoid and stress pathways, while abscisic acid influences gene expression downstream of HSFA1 without broadly reshaping chromatin. A cross‑species, cross‑condition machine‑learning framework successfully predicts chromatin accessibility and expression, underscoring a conserved regulatory logic in stress responses.

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.

A biparental Vicia faba mapping population was screened under glasshouse conditions for resistance to a mixture of Fusarium avenaceum and Fusarium oxysporum, revealing several families with moderate to high resistance. Using the Vfaba_v2 Axiom SNP array, a high-density linkage map of 6,755 SNPs was constructed, enabling the identification of a major QTL on linkage group 4 associated with partial resistance to foot and root rot.

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 mapped the subcellular localization of isoprenoid biosynthetic enzymes in Marchantia polymorpha, confirming most predictions and identifying oil body cells as primary sites of terpene synthesis. Overexpression and CRISPR knockout of the ABC transporter ABCG1 revealed its essential role in retaining sesquiterpenes within oil bodies, while attempts to boost heterologous diterpene and triterpene production in oil bodies did not increase yields.
