Dr. Lorenzo Rossi

Horticultural Science Root Biologist

Lorenzo Rossi joined IRREC in January, 2018. He is the center’s Plant Root Biologist. Dr. Rossi's appointment demonstrates the University of Florida’s Institute of Food and Agricultural Science’s commitment to leading the citrus industry in its management of citrus greening while scientists continue their search for a cure for this devastating disease.

Dr. Rossi is known for his successful research experiments with fruit crop trees in Florida, Italy, North Carolina, and in Texas, where he evaluated genetic and environmental stresses on roots. Root stress experiments included topics such as drought, salinity, heavy metals, emerging pollutants, and climate change. His work with Florida citrus trees focuses on the tree roots, which are the first part of the tree to show symptoms of huanglongbing, or citrus greening infection. His research program involves field and laboratory experiments using instruments that measure roots and photograph root growth daily.

Dr. Rossi uses the most recently developed tools to study root physiology and biology. With root system images captured both in the field and in the laboratory, he is creating both two and three dimensional computer images to study finite spaces inside root architectures. The images assist Dr. Rossi in his work to understand root stocks and needed modifications for the development of disease-resistant trees and long-term solutions.

Prior to Dr. Rossi’s appointment at UF/IRREC, he completed three post doctorate positions: Missouri University of Science and Technology, Texas A&M University, and North Carolina State University. He graduated Italy’s most prestigious scientific university, Scuola Superiore Sant’Anna, at the Biolabs, within its Institute of Life Sciences, in Pisa, Italy.

Dr. Rossi is accepting visiting scholars, scientists and graduate students to his laboratory. Please email him at: l.rossi@ufl.edu
