| During development plants usually have to encounter simultaneously with multiple nutrient stress conditions. Until now research has been mainly focused in the study of plant responses to individual stresses, and understanding of adaptation to combinatorial stress is reduced, but indicative of non-additive genetic effects. Different of transcriptomic and metabolomic analysis and functional characterization of individual genes has found out a significant crosstalk between signaling pathways for nutrient and water stress adaptation. We are interested in the study of regulatory networks and signaling pathways involved in plant responses to adverse conditions such as limitation of water and nutrients like nitrate and sulfur and to identify new candidate genes that can be used in a new generation of improved-biomass-breeding programs in crops. The tolerance to these heterogeneous stresses is a very complex phenomenon, which involve a flexible and dynamic metabolic adjustment that implies changes in nutrient use efficiency, partitioning of assimilates and changes in plant organs like roots and cell structures as the plant cell wall and endoplasmic reticulum. We set up comprehensive forward genetic screenings and systems biology approaches that allow us to identified different Arabidopsis transcription factors that might be involved in metabolic adjustment in response to those nutrition limitations. Remarkably, overexpression of some those transcription factors in tomato, enhance tolerance to several nutrient deficiencies and significant increase in biomass production. | |
