Isoprenoid biosynthesis, specificities and homeostasis in plants : genetic approach for the identification of regulators by screening for suppressors of growth defect

Abstract : Plants produce a great diversity of natural compounds, among which isoprenoids prevail. These molecules have essential functions for growth and development: plant hormones, growth regulators as brassinosteroids, photosynthetic pigments, acting on major biological processes. Thus, germination, flowering, heat and draught stress tolerance, or seed production are controlled by the action of isoprenoids. The aim of my project is to identify by genetic selection the regulators of isoprenoid homeostasis. For this, I carried out genetic screens for suppressors of growth defects in two isoprenoid biosynthesis deficient Arabidopsis thaliana mutants and a brassinosteroid signaling Hordeum vulgare mutant. The second part of my project was focused on the specific sterol biosynthetic pathway occurring in a specialized cell type, the germinating pollen tube.
