This $907,847 federal Project Grant award from the National Science Foundation's (NSF) Biological Sciences program (CFDA 47.074) aims to advance the fundamental knowledge of the molecular mechanisms governing early root growth in response to phosphate deficiency in the model plant Arabidopsis thaliana.
The primary objectives are to determine the regulatory pathway involving the crucial kinase ARSK1 that controls root adaptation to phosphate availability, and to disseminate the research findings through education and outreach activities. The project employs a combination of computational, biochemical, and molecular physiology approaches to investigate the transcriptional and post-translational regulation of ARSK1. The results are expected to increase understanding of the signaling cascade connecting nutrient levels and organ growth control. The award will also provide training opportunities for postdoctoral, undergraduate, and high school students, and engage underrepresented groups through outreach initiatives.
