UD researchers show how beneficial soil bacteria can boost plant immunity
With the help of beneficial bacteria, plants can slam the door when disease pathogens come knocking, University of Delaware researchers have discovered.
A scientific team under the leadership of Harsh Bais, assistant professor of plant and soil sciences in UD’s College of Agriculture and Natural Resources, found that when pathogens attempt to invade a plant through the tiny open pores in its leaves, a surprising ally comes to the rescue. Soil bacteria at the plant’s roots signal the leaf pores to close, thwarting infection. (more…)
