The establishment of embryonic polarity axes foreshadows the main body structure of multicellular adult organisms. Plants developed a polar cell-to-cell transport of the growth hormone auxin to generate an asymmetric auxin response in embryos, instructive for apical-basal polarity axis formation. Using theory-guided experiments, I recently established that the dynamic spatial and temporal onset of auxin biosynthesis is a trigger to orient auxin fluxes and therefore apical-basal axis body axis, at various time points of Arabidopsis embryo development. Here I proposed a direct approach to understand how auxin biosynthesis influences embryo patterning and how this is translated into gene expression changes. The objectives of my project are: (i) to characterize the downstream elements of the auxin response activated by a embryonic local auxin production, (ii) to identify the factors that dynamically and developmentally control auxin biosynthetic genes expression. The proposed research is groundbreaking, as it will provide novel foundations for understanding mechanisms of polarity axes establishment mediated by auxin in plants. The results will also have potential agronomic applications in seed quality control, essential for food and seed stocks quality.
