Working model of chromatin signatures from nuclease sensitivity profiling using
DNS (Differential Nuclease Sensitivity) mapping, from Vera et al., 2014.
Hop meiotic prophase chromosomes and telomeres, from KA Easterling:
Research and Professional Interests:
Our work makes use of maize (corn, Zea mays L.) to define structure-function relationships of heredity and gene regulation across multiple scales. We employ genetics, microscopy, molecular biology, and genomics technologies.
Current research is advancing in several related areas, including:
Meiotic Chromosome Behavior
- Meiotic telomeres, nuclear envelope SUN-domain, LINC complex proteins in chromosome segregation
- Meiotic chromosome behavior in hop
Epigenomics and chromatin structure
- Development of genome-wide nuclease sensitivity and open chromatin profiling technologies for plants
- Analysis of genome-wide DNA damage signaling pathways in maize and human
- Spatiotemporal mapping of DNA replication in nuclei from a naturally developing multicellular organism
- G-quadruplex (G4) DNA in maize as potential regulatory motifs for plant energy stress
