Abstract
Each cell of a multicellular organism generally contains the same DNA sequence. Yet, a single organism is composed of hundreds to thousands of highly diverse and functionally unique cell types. This diversification is largely the result of differential gene regulation; distinct cell types express unique sets of genes that encode their identity and dictate their functions. At the forefront of gene regulation are cis-regulatory elements that control “when” and “where” a gene is expressed. Mutations within CREs can perturb the native pattern and magnitude of gene expression and result in drastic molecular, cellular, and morphological phenotypes, including developmental defects in plants and diseases in humans. Until recently, it has been impossible to profile active CREs from diverse plant cell types at scale. I will discuss new efforts to chart cis-regulatory variation within and across several plant species at the level of individual cells and the implication towards phenotypic innovation.
