Prof. Dr. Aaron M. Rashotte

Professor of Biological Sciences at Auburn University, Alabama, USA.

Aaron Rashotte got his Ph.D. in Plant Sciences at the University of Arizona. After postdoctoral stays at Wake Forest University and the University of North Carolina at Chapel Hill, he moved to Auburn University in Alabama, where is currently a Professor in Biological Sciences. Aaron Rashotte’s overall research interests are focused on both development and effects of abiotic stress on plants, with a specifically interest in how the plant hormone cytokinin is involved in these processes. Rashotte’s lab uses molecular, genetic, and physiological approaches to study a set of transcription factors known as Cytokinin Response Factors (CRFs), which are regulated by both cytokinin and stress. A major goal of his research is a better understanding of how cytokinin and stress interact through CRFs in both Arabidopsis and tomato to control essential plant processes and development.

Cytokinin is a plant hormone well-known to be involved with plant growth and developmental processes with an increasing evidence of involvement in environmental stress responses. Cytokinin Response Factors or CRFs are a group of transcription factors identified with connections to both cytokinin and abiotic stress. Using transgenic lines with altered CRF levels we have examined the role that CRFs play in different abiotic stress responses, including oxidative, cold, and salt stress response. This has been done in experiments examining different physiological measurements, transcriptome profiling, and measurements of cytokinin levels after changes in stress response. This work has revealed that specific stress responses of CRFs appears to mirror phylogenetic groupings of these proteins into clades that have deeply distinct evolutionary lineages that are conserved throughout Angiosperms. Sequence-based analysis of promoter elements from each CRF Clade across plants support these findings. Arabidopsis based work suggest roles of different clades in different abiotic stress responses: Clade I – Salt and Osmotic, Clade II – Cold, and Clade III – Oxidative.
