Chemical Genomics Translatability from Unicellular to Multicellular Models

: Chemical genomics has proven to be a useful and successful approach to study complex systems where conventional genetics fails to render feasible results. High-throughput phenotype screenings in model organisms have identified a large collection of powerful and selective bioactive chemicals. Nevertheless, applying chemical high-throughput screening to crops still represents a big challenge for researchers. Fortunately, a circumvent approach could be taken by means of translational research. In this case, searching bioactive chemicals in a much handy model organism would be the starting point for discovering compounds with activity in relevant plants for improving a desirable trait. In this chapter, we describe strategies that have been proven to successfully translate chemical biology and genetics from unicellular yeast to Arabidopsis thaliana and finally to crops.
