Bio

The most significant contribution Dr. Argelia Lorence has made to plant sciences has been the discovery of a novel biosynthetic pathway for vitamin C that involves myo-inositol as a main precursor. Her laboratory uses Arabidopsis to better understand the role of various subcellular pools of vitamin C in plant physiology. Her ongoing research has potential applications for the development of crop plants with enhanced nutritional content, better growth, and improved tolerance to multiple environmental stresses. In addition to Arabidopsis, her current models of study include rice, soybean, tobacco and maize.

Dr. Lorence directs the high throughput plant phenotyping facility at A-State. She co-directed the Plant Imaging Consortium, PIC, a multi-state effort that uses phenomics and other imaging techniques to allow researchers to adapt crops to meet the challenges of a changing climate and a growing world population. She is also co-principal investigator of the Wheat and Rice Center for Heat Resilience, project focused on finding novel genes involved in conferring rice and wheat tolerance to high night temperature, one of the key factors limiting the yields of the two most important crops in the world for food security.

Since joining A-State in 2005, Dr. Lorence has secured over $18 million in grants from the National Science Foundation, the National Institutes of Health, and the U.S. Department of Agriculture. Her accolades include the Arthur Neish Young Investigator Award from the Phytochemical Society of North America (PSNA), Featured Mentor from the Minority Environmental Leadership Development Initiative, Distinguished Woman in Science by the Congress of the State of Morelos, and the Outstanding Hispanic Achiever of the Year Award from Hispanic Community Services in Jonesboro. She received an Endowed Professorship for her contributions to research and teaching at A-State in 2017.

Prior to joining A-State, Dr. Lorence was a post-doctoral research associate at Texas A&M and at Virginia Tech. Dr. Lorence received a doctorate in 1997 and a master’s degree in biotechnology in 1995 from the National Autonomous University of Mexico (UNAM). She earned a bachelor’s degree in biochemical engineering from Autonomous Metropolitan University (UAM) in 1991.
