Mark Beilstein

Dr. Mark Beilstein is a Professor and Director of Graduate Studies in the Department of Plant Sciences at the University of Arizona, with primary affiliation to the Biodiversity & Evolutionary Biology program. His research focuses on plant genetics, evolutionary biology, and RNA biology, particularly in the Brassicaceae family. He investigates mechanisms of epigenetic regulation, gene evolution, and non-coding RNA functions in plant development, stress responses, and speciation. Key contributions include studies on telomere biology, RNA-directed DNA methylation, and the role of long intergenic non-coding RNAs (lincRNAs) in Arabidopsis and other plants.

His work bridges molecular genetics with evolutionary processes, addressing questions about gene duplication, introgression, and adaptive divergence. He has developed tools for analyzing non-coding RNAs and contributed to genomic studies of crops like Camelina sativa. Dr. Beilstein’s research also extends to biochemical approaches modeling human genetic disorders, such as pontocerebellar hypoplasia.

Notable themes across his publications include epigenetic regulation under stress, evolutionary dynamics of gene families, and plant genome architecture. His studies highlight the interplay between genetic, epigenetic, and environmental factors shaping plant diversity and function.
