How does your garden grow? Transcriptional regulation of Arabidopsis cell type development, mineral nutrient acquisition and defense metabolite biosynthesis

A major component of gene regulation in the model plant, Arabidopsis thaliana, is transcriptional regulation. Transcriptional regulation in individual cell types, in response to the environment and of central biological processes is essential for plant growth and function. We have mapped transcriptional regulatory networks spatially and temporally controlling xylem cell development in the root and stem, defense metabolite biosynthesis and nutrient use and metabolism. Emerging principles from our analyses of these networks include the importance of feedforward loops in ensuring the robust regulation of terminal differentiation, non-linear transcriptional control of metabolite biosynthesis, and combinatorial, treatment-dependent rewiring of mineral nutrient homeostasis.
