Professor
Thomas Okita is a Regents Professor at Washington State University (WSU), affiliated with the Department of Plant Sciences within the College of Agricultural, Human, and Natural Resource Sciences. He holds a Ph.D. in Plant Biology from the Scripps Institution of Oceanography, UC San Diego (1978). His research focuses on two primary areas: RNA localization mechanisms in plant cells and the multifunctional roles of plastidial phosphorylase in plant metabolism. In RNA localization, Okita investigates how storage protein mRNAs are targeted to specific ER subdomains in rice endosperm, identifying cis-elements and trans-factors like RNA-binding proteins (RBPs). His work employs co-immunoprecipitation, yeast 2-hybrid, and seCLIP technologies to study RBP interactomes and regulon hypotheses. In the second area, he explores the structural and functional roles of rice plastidial phosphorylase (Pho1), particularly the L80 peptide's regulatory influence on starch synthesis and photosystem I interaction. Okita's recent articles emphasize RNA-binding proteins in salt stress responses, host-pathogen interactions (e.g., Ralstonia solanacearum), and the interplay between source-sink dynamics and plant productivity. His studies bridge molecular mechanisms (e.g., transcriptome reprogramming, protein complex assembly) with applied goals like enhancing crop yields through genetic manipulation of starch metabolism. His lab, the Okita Laboratory, integrates proteomics, biochemistry, and genetic engineering to address fundamental questions in plant physiology and biotechnology. Current projects include optimizing starch synthesis pathways and dissecting the role of Pho1 in photosynthetic efficiency.
