COLUMBIA, Mo. – Previous studies have suggested that plant growth can be influenced by sound and that plants respond to wind and touch. Now, researchers at the University of Missouri, in a collaboration that brings together audio and chemical analysis, have determined that plants respond to the sounds that caterpillars make when eating plants and that the plants respond with more defenses.

New line of pigs do not reject transplants, will allow for future research on stem cell therapies
COLUMBIA, Mo. – One of the biggest challenges for medical researchers studying the effectiveness of stem cell therapies is that transplants or grafts of cells are often rejected by the hosts. This rejection can render experiments useless, making research into potentially life-saving treatments a long and difficult process. Now, researchers at the University of Missouri have shown that a new line of genetically modified pigs will host transplanted cells without the risk of rejection. (more…)
Enzyme map created by using a high-powered X-ray device
COLUMBIA, Mo. – The human body is full of proteins called enzymes that help nearly every function in the body. Scientists have been studying enzymes for decades in order to learn how they work and how to create better drugs and medical treatments for many ailments. Now, University of Missouri researchers have completed a 3-D map of an enzyme called Proline utilization A (PutA). PutA facilitates metabolism by adding oxygen to molecules. John Tanner, a professor in the MU Department of Biochemistry, says mapping this enzyme will give researchers a better understanding of its function, which could help drug manufacturers create more effective drugs.

COLUMBIA, Mo. –Vitis vinifera are common grapevines and are the world’s favorite wine-producing varietal. However, research has shown that grapevines are susceptible to powdery mildew, a plant disease, which contributes to significant crop loss for most commercial wine varietals that are cultivated each year. Now, researchers at the University of Missouri have used frog eggs to determine the cause of this disease, and have found that a specific gene in the varietal Cabernet Sauvingon, contributes to its susceptibility.

Findings could lead to natural bacterial anti-infectives in food-producing plants
COLUMBIA, Mo. – When bacteria attack plants, they often inject harmful proteins into the host plants’ cells to weaken and suppress natural defenses. However, in some plants, bacteria attack once they’ve recognized the plant cells as a potential host. Now, researchers at the University of Missouri have identified and replicated the process that allows the bacteria—known mostly for attacking tomatoes—to invade its host. This discovery could lead to natural anti-infective treatments that work with food-producing plants to enhance resistance to harmful bacteria in the field. (more…)
COLUMBIA, Mo. – Lowland South America, including the Amazon Basin, harbors most of the last indigenous societies that have limited contact with the outside world. Studying these tribes, located deep within Amazonian rainforests, gives scientists a glimpse at what tribal cultures may have been like before the arrival of Europeans. Now, researchers at the University of Missouri have used satellite images to assess the demographic health of one particular village of isolated people on the border between Brazil and Peru. Remote surveillance is the only method to safely track uncontacted indigenous societies and may offer information that can improve their chances for long-term survival. (more…)
Study finds that improved turf management techniques help golf course ecosystems succeed.
COLUMBIA, Mo. – Currently, there are more than 18,300 golf courses in the U.S. covering over 2.7 million acres. The ecological impacts of golf courses are not always straightforward with popular opinion suggesting that environmentally, golf courses have a negative impact on ecosystems. Now, researchers at the University of Missouri have determined that golf courses can offer a viable habitat for stream salamanders, and enhanced management practices may be beneficial to ecosystems within golf courses.

Study shows blue logos invoke feelings of reliability, red logos invoke expertise
COLUMBIA, Mo. – Many studies have shown that a company’s logo is one of the most important aspects of marketing and advertising a brand, or features that distinctly identifies a company’s product or service from its competitors. Now, a researcher at the University of Missouri has found that the specific colors used in a company’s logo have a significant impact on how that logo, and the brand as a whole, is viewed by consumers.
Jessica Ridgway, a doctoral student in the MU Department of Textile and Apparel Management, surveyed 184 adults using generic logos of different colors for fake companies that she created. She then asked participants to describe the emotions they felt toward the fake companies upon seeing each logo. Ridgway was able to identify key characteristics that each logo invoked, based on which colors were used. (more…)
