Research focus

Variation in regulatory elements is a major cause of phenotypic diversity, yet notoriously difficult to pinpoint. We developed FIND-CIS, a combined transcription factor foot-printing assay (MOA-seq), RNA-seq, and F1 hybrids to quantify functional variation that affects gene regulation. Our aim is to improve biotic and abiotic traits in cops by targeted editing of cis-elements. We also strive to understand the evolution, dynamics, and diversity of cistromes.
