Descripción
Plants as sessile organisms have developed complex sensing and signaling mechanisms to perceive and properly respond to dynamic changes of their variable environmental conditions. Nutrient availability and assimilation are key environmental factors for plant growth and development. Among nutrients, nitrogen (N) and sulphur (S) are crucial for plants to perform their cellular activities. In addition, N and S metabolism must be tightly coordinated with cellular carbon (C) to sustain optimal growth in all living organisms. During the last years different DNA microarray studies revealed that an important fraction of the Arabidopsis transcriptome is regulated by S, C, N or C-N combinations, suggesting that the efficient assimilation of those nutrients implies a tightly regulation of gene expression. In order to identify key factors controlling nutrient assimilation in Arabidopsis, we are screening a collection of transgenic lines individually transformed with different transcription factors under control of an estradiol inducible promoter. Under inducible conditions, survival and performance of individuals will be tested for different N, S, and C-N conditions. The results of the ongoing screening will be presented in the meeting.
