Performance Plants Inc. solves decades-old drought-tolerance puzzle

Novel YPT™ plant technology enhances crop yield while protecting plants from drought

For immediate release

KINGSTON, ON -- Performance Plants Inc., a spinoff company of Queen's University's PARTEQ Innovations, has announced the successful completion of field trials using a novel technology that enhances crop yield while protecting against drought stress.

Data gathered from three years of field trials in multiple sites have shown that transgenic canola plants grown with the company's Yield Protection Technology (YPT™) consistently out-yielded the control plants by up to 26 per cent under various water stress and optimal conditions.

The findings, published recently in the on-line edition of The Plant Journal, represent a significant breakthrough in solving the drought stress problem, which has been profoundly affecting crop yield worldwide.

Although researchers have attempted for several decades to develop crops that can cope with drought stress, relatively little progress has been made, as the drought tolerance gained from these attempts often results in lower seed yield, says Dr. Yafan Huang, corresponding author of the paper and Chief Scientific Officer of Performance Plants. “The ability to maintain or enhance crop yield under well-watered or drought conditions is a very important aim for plant biotechnologists, since high yield is a major benefit for both farmers and consumers.

“The revolutionary aspect of this technology is that the drought tolerance and yield protection mechanism is controlled by a built-in molecular switch that is only turned on when plants sense lack of water in the soil,” he says. “This cleverly engineered mechanism allows plants to achieve maximum productivity under different growth conditions.”

Dr. David T. Dennis, President and CEO of the company, says “This is one of the first examples of the next generation of plant technologies that is demonstrated at the level of the field, and it involves manipulating the plant's own genes. For this reason, we believe this study is fundamentally important in providing a solution for the enhancement of crop productivity worldwide.”

Given current global conditions, developing a drought tolerance technology to protect crop yields is of paramount importance, says Dr. Charles Arntzen, Florence Ely Nelson Presidential Chair, Regent's Professor at Arizona State University, and a member of the U.S. National Academy of Sciences, specializing in plant biotechnology. “In the last 50 years, our global population has increased from around 2.5 to 6 billion persons but arable land remained nearly constant. As we have intensified agriculture to produce more food for a burgeoning population, about half of our freshwater ecosystems have been lost," he says. "Creating more water-efficient crops is essential in coming decades if we hope to meet further population growth, as well as the increases in global affluence and corresponding desires for improved foods."

Performance Plants continues to test its YPT™ technology for the fourth year in canola while developing the technology in other important crop species such as corn, soybean and cotton.
