Breakthrough 3D Genome Mapping Reveals How Plants Control Photosynthesis
- Chinese scientists have developed a groundbreaking 3D genome mapping technology that sheds new light on plant genome architecture, particularly in photosynthesis regulation.
- The innovative technique called Transposase-Accessible Chromosome Conformation Capture (TAC-C) combines ATAC-seq and Hi-C to efficiently map chromatin interactions in plant genomes.
- TAC-C overcomes limitations of previous tools by providing high resolution and targeted mapping of chromatin interactions.
- The research reveals that chromatin hubs correlate with gene expression levels and play a critical regulatory role in plant genomes.
- Asymmetrical chromatin interactions were observed in the hexaploid wheat genome, affecting gene expression patterns inherited from different ancestral genomes.
- The study identifies plant-specific transcription factors at chromatin interaction anchors, influencing gene expression and genome organization.
- Mutants deficient in SBP transcription factors show disrupted chromatin loops associated with photosynthesis-related genes, impacting leaf development and photosynthetic efficiency.
- The research highlights the role of SBP proteins in modulating chromatin architecture to regulate gene expression for plant development and photosynthesis.
- Insights from this study provide valuable implications for agricultural biotechnology, offering potential for crop improvement through manipulation of gene expression and genome architecture.
- TAC-C technology's benefits include enhanced resolution, cost-effectiveness, and democratizing access to advanced genome architecture studies in diverse plant species.
