Working model of chromatin signatures from nuclease sensitivity profiling using
DNS (Differential Nuclease Sensitivity) mapping, from Vera et al., 2014.
Research and Professional Interests:
Our work makes use of maize (corn, Zea mays L.) as a model genetic system to investigate fundamental questions about the inheritance and function of genetic material at the cellular and molecular level. We employ genetics, microscopy, molecular biology, and genomics to examine chromosome form and function. Our work has broad implications for not only plant biology, but also for genetics more broadly.
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 using genome-wide nuclease sensitivity profiling
