Senesco Technologies, Inc. ("Senesco" or the "Company") (AMEX:SNT) today announced that John Thompson, Ph.D., FRSC, the Company's Executive Vice President of Research and Development, and his research associates, will be making several presentations at the Seventh International Congress of Plant Molecular Biology held June 22-27, 2003, in Barcelona, Spain. The conference is expected to be attended by approximately 2,000 scientists from around the world and is among the industry's premier events for the exchange of information and the presentation of research findings.

Dr. Thompson noted, "The International Congress of Plant Molecular Biology is an excellent presentation venue for Senesco. The Company's agricultural technology is currently being commercialized in four major crops (lettuce, trees, alfalfa and banana) and is increasingly attracting attention for commercialization in a broad spectrum of additional agronomic and horticultural crops. The Congress is held every three years and is attended by leading scientists from Academe and the agri-biotechnology industry around the world."

Dr. Thompson further commented, "We will be presenting new data pertaining to the use of Senesco's technology to enhance the growth and yield of agronomic crops and to inhibit the ability of pathogens to induce programmed cell death in plants. The Congress venue will provide the opportunity for a detailed discussion of the Company's technology with the scientific community and with additional prospective commercialization partners."

Bruce Galton, President and CEO of Senesco, commented, "We are truly delighted to have five formal presentations at this prestigious plant biology conference. The presentations cover many of our areas of concentration and demonstrate the broad scope of our research."

The Company's presentations will detail findings from experiments conducted at the University of Waterloo under the direction of Dr. Thompson. The experimental findings are related to controlling senescence in plants through the regulation of genes that include DHS, Factor-5A and lipase.

Dr. Thompson and his research associates will be making the following formal presentations at the Seventh International Congress of Plant Molecular Biology:

• Suppression of Deoxyhypusine Synthase Expression in Arabidopsis thaliana Delays Leaf Senescence
• Characterization of a Wounding-induced Isoform of Eucaryotic Translation Initiation Factor 5A in Arabidopsis
• Characterization of a Putative Cell Division Isoform of Eucaryotic Translation Initiation Factor 5A in Arabidopsis thaliana
• Down-regulation of a Plastid-Associated Lipase in Arabidopsis Inhibits Post-germination Seedling Growth
• Over-expression of Hydroperoxide Lyase in Arabidopsis Confers Increased Tolerance to Sublethal Stress and Enhanced Resistance to the Bacterial Pathogen, Pseudomonas syringae pv. Tomato.
