Hypothesized root epidermal -Fe mechanism. Model depicting epidermal root development (blue box) and general stress responses (yellow box) epistatic to the known -Fe response. Dash grey arrows indicate direct or indirect connections identified by the DPGP clustering and Logistic regression with LASSO modeling algorithms on the -Fe spatiotemporal RNA-seq data. Solid black arrows indicate confirmed direct -Fe interactions. Genes in red are potentially post-transcriptionally regulated
