Agricultural Research Service (ARS) scientists in Albany, California, have found a way to streamline the process that scientists use to insert multiple genes into a crop plant, developing a reliable method that will make it easier to breed a variety of crops with vastly improved traits. The technology is expected to speed up the process for developing new varieties that are better equipped to tolerate heat and drought, produce higher yields and resist a myriad of diseases and pests. “Making genetic improvements that were difficult or impossible before will be much easier because we can now insert not just one or two genes, but multiple genes, into a plant in a way that will lead to predictable outcomes,” said Roger Thilmony, an ARS molecular biologist in Albany.
A paper describing the so-called GAANTRY gene stacking technology was published yesterday in the August issue of The Plant Journal. The technology will be freely available to anyone interested, and J.R Simplot Company is planning to use it to introduce multiple genes into potatoes to make them more resistant to late blight.
“We have struggled to put multiple late blight resistance genes into potatoes for years. They are very long, complex genes, and with existing technologies it’s been extremely difficult. But the GAANTRY technology will help us tremendously,” said Craig Richael, a director of research and development for J.R. Simplot. Read ARS press release
