MpHSFB1 is required in Marchantia polymorpha to activate cell-type-specific terrestrial adaptation programs, coordinating cytokinin and ROS homeostasis.
- Why it matters: Regulatory logic linking developmental innovation to stress signaling during the land transition remains unclear, limiting understanding of how plants integrated growth with tolerance.
- What they did: The study used single-nucleus RNA sequencing and gene regulatory network analysis to define MpHSFB1-dependent programs and HSFB1 regulons across plant lineages.
- The result: MpHSFB1 operates via modular bHLH partnerships: it co-opts MpbHLH21/40 for developmental morphogenesis and recruits MpbHLH51 for resistance to prolonged heat stress, implying evolutionary rewiring and subfunctionalization.
