In a new Perspective by Wurtzel et al., the authors lay out SynBio’s tremendous potential to transform agriculture. Consider how we might leverage the “vast design space that plants have not occupied.” As an example, plants employ two pathways to fix carbon, and prokaryotes another six, but scientists…

Chromoplasts are a type of plastid, usually found in fruits and flowers, that can accumulate large amounts of carotenoids including beta-carotene (pro-vitamin A). It has been proposed that increasing chromoplast formation could be a way to enhance human consumption of vitamin A. In a new report, Llorente…

ABA is synthesized in response to water stress and promotes stomatal closure, thus decreasing transpiration. Crop yields can be increased by controlling transpiration early in the growing season, ensuring that soil water resources persist through the seed-set period. Building upon earlier studies, Vaidya,…

Dr. Raimund Nagel Iowa State University Plants produce a plethora of natural products that function as defensive compounds are frequently used by humans for medicinal purposes. A majority of these natural products, however, are either found in low concentrations, in slow growing plants, or are…

Promoter regions upstream of transcription start sites contain DNA regulatory elements (RE) crucial for the transcriptional control of gene expression. However, REs are short degenerated sequences with low conservation during evolution. In this paper, Lieverman-Lazarovich et al. studied REs in core hormone…

Synthetic biology is a set of tools, a way of thinking, the integration of engineering principles into biological sciences, and potentially the biggest opportunity for advances in plant sciences since PCR. Yet many struggle to define it, and fewer still grasp its full potential. What is synthetic…

What does your lab work on? We combine functional genomics with synthetic biology approaches to study the metabolism of redox-active plant natural products that can harnessed for applications relevant to agriculture and human health.  We are particularly interested in specialized quinones like…
