Description: A hallmark feature of plant development is predictable, yet flexible, postembryonic organogenesis. Organ formation in plants occurs de novo from stem cell populations termed apical meristems that are present in the root and shoot. Decades of genetic studies have established relationships between genotype and phenotype, but in many multicellular organisms such associations are still unknown. To identify new plant growth factors, my research team employs a novel "proteotype" approach that leverages proteomics data to discover thousands of proteins that underpin plant phenotypes. We have discovered numerous proteins that influence root stem cells in the model plant Arabidopsis and maize using this method. Our studies have deepened our understanding of plant cell biology by examining links between auxin and cellular proliferation, cell wall dynamics, and plasmodesmata in roots. Research in my lab is expanding our genetic understanding of plant growth in response to molecular cues, generating large-scale open access phenomic datasets, and facilitating biological network discovery that is needed to inform agricultural strategies for increased yield.
