Think that a field of plants is a bucolic place free of strife? Try again. It is a battlefield of chemical warfare between defending plants and attacking pathogens. And the plants are waging a good fight, according to a University of Missouri biochemist. Previous studies have shown that plants can sense attacks by pathogens and activate their defenses. However, it has not been known what happens between the pathogen attacks and the defense activation, until now. A new MU study revealed a very complex process that explains how plants counterattack pathogens. This discovery could potentially lead to crops with enhanced disease resistance.

Things have been rough for the bobwhite quail since the 1950s when intensive “fence row to fence row” farming destroyed much of their habitat. Today’s quail population is about one-fifth of what it was during those days.
Three days of rain doesn’t sound like much—unless it comes in prodigious quantities and on top of months of above-average rainfall that saturates the ground. Spring 2008 is seeing significant flooding in the Mississippi River valley.
A survivor of uncounted tornadoes and lightning strikes, the 90-ft. tall, 91-inch wide tree was stressed. Probably the second largest bur oak in the nation, the soil around it has been compacted by cars and some of its dead limbs were infested with wood decay that threatened the other branches and trunk.
For years, scientists have studied cystic fibrosis using mice in which the cystic fibrosis gene was altered. However, mice do not develop lung disease like humans with cystic fibrosis. Now, researchers at the University of Missouri and the University of Iowa have taken the first step in developing a cystic fibrosis model with animals more common to humans—pigs.
For the second year, students in Mary Ann Gowdy’s floral design class at the MU College of Agriculture, Food and Natural Resources have ended their eight-week course by numbering-off into four-person teams to create the most attractive arrangement based on flowers, vases and accruements provided by Gowdy. Their final product goes on display on front of the Dean’s office in the Agriculture Building where faculty, staff, students and passers-by can vote on their favorite arrangement.
Paul R. Vaughn, associate dean for the University of Missouri College of Agriculture, Food and Natural Resources, was presented the 2008 Distinguished Alumni Award from The Ohio State University. Vaughn, who earned his Ph.D. in Agricultural Education there in 1976, was recognized for his leadership in academic programs at MU and his contribution in several national educational organizations, from the…
BridgeAt first glance, there seems to be little in common between biochemistry research in medicine and agriculture. On closer inspection, the relationship becomes profound as life and disease processes are very similar at the genetic and molecular level.
Once, buffalo roamed the American prairie in complex societies where offspring were raised and protected according to instinct and learned responses. Today’s descendants of these vast herds live on preserves under the care of wildlife managers.
It’s hard enough for a scuba diving newcomer to plant coral seedlings in a seabed on the other side of the world. It is harder still when a NBC TV news camera follows your every move. During Winter Break, 15 MU College of Agriculture, Food and Natural Resources students spent three weeks studying conservation and biodiversity in Thailand.
