SbEREB167 and SbEREB174 (AP2/EREBP family) efficiently induce somatic embryogenesis and regeneration in sorghum, identifying two prioritized transcription factors as strong developmental regulators.
- Why it matters: Genotype-specific defense transcriptional states and limited embryogenic competence hinder sorghum transformation, leaving a need to map how developmental regulators overcome these barriers.
- What they did: The authors performed multi-layer transcriptomics of somatic embryogenesis and regeneration across two sorghum genotypes (Tx2910, Tx2783), two explant types (immature embryos, leaf bases), and three DR treatments (GRF-GIF, WUS, BBM+WUS), using bulk RNAseq and single-nucleus transcriptomics.
- The result: WUS suppresses defense and stress signaling early while activating fate-specification programs, and GRF-GIF drives a delayed shift toward proliferation and morphogenesis, enabling DR-mediated exit from defense-locked states.
