COLUMBIA, Mo. – The University of Missouri has Jesse Hall, Faurot Field, Memorial Union and the Columns. Now, MU has its own bug. An MU researcher has discovered a new insect on campus and given it a Mizzou name. Ben Puttler, assistant professor emeritus of plant sciences at the College of Agriculture, Food and Natural Resources, first discovered Aphis Mizzou in 2005 while conducting research on wasps on the MU campus.

The insect, Aphis Mizzou, is a member of the aphid family of bugs. Aphids are tiny insects that live by feeding on the sap of plants. Nearly all annual and perennial plants, including shrubs and trees, are potential hosts for aphids. When feeding on these plants, aphids can crumple leaves, distort plant tissue and bend stems. There are 5,000 species of aphids known in the world, but only 150 live in North America. (more…)

Zinc Helps against Infection by Tapping Brakes in Immune Response

COLUMBUS, Ohio – New research suggests that zinc helps control infections by gently tapping the brakes on the immune response in a way that prevents out-of-control inflammation that can be damaging and even deadly.

Scientists determined in human cell culture and animal studies that a protein lures zinc into key cells that are first-responders against infection. The zinc then interacts with a process that is vital to the fight against infection and by doing so helps balance the immune response. (more…)

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…)
