| In nature, plants during development usually have to deal simultaneously with multiple nutrient stress conditions. Currently research has been limited to responses to individual stresses, and understanding of adaptation to combinatorial stress is reduced, but indicative of non-additive interactions. A number of transcriptomic and metabolomic analysis and functional characterization of individual genes has discovered a convergence of signaling pathways for nutrient stress adaptation. Our research line is focus on the study of regulatory networks and signaling pathways involved in plant responses to adverse conditions such as limitation of nitrate and sulfur and to identify new target genes that can be used in a new generation of improved-biomass-breeding programs in monocot species. The tolerance to this kind of stresses is a very complex phenomenon, involving a metabolic adjustment that implies changes in nutrient use efficiency, partitioning of assimilates and changes in plant organs such as roots and cell structures as the plant cell wall and endoplasmic reticulum. Using forward genetic screenings and systems biology approaches we have identified a set of Arabidopsis transcription factors that might be involved in metabolic adjustment in response to those nutrition limitations. Wide Genomic and syntenic analyses allow as identifying putative orthologous genes in monocot species such as maize and wheat. Remarkably, overexpression of putative orthologous maize transcription factors in the model plant Arabidopsis, promotes a significant increase in biomass production and tolerance to several nutrient deficiencies. | |
