The anatomy of petal drop in sunflowers
Anatomical analysis of two sunflower cultivars revealed a differentiated region at the junction of the flowers' petal and achene. Cell division at the abscission zone of the short-lived cultivar occurred earlier than in the long-lived cultivar, indicating that the tempo of development differed; the abscission layer reached full maturity sooner in Procut Bicolor, resulting in earlier petal drop, than in Procut Yellow Lite. Vase life was also correlated to flower color. (2015-01-14)

Olive oil more stable and healthful than seed oils for frying food
Frying is one of the world's most popular ways to prepare food -- think fried chicken and french fries. Even candy bars and whole turkeys have joined the list. But before dunking your favorite food in a vat of just any old oil, consider using olive. Scientists report in ACS' Journal of Agricultural and Food Chemistry that olive oil withstands the heat of the fryer or pan better than several seed oils to yield more healthful food. (2014-10-22)

Vitamin E intake critical during 'the first 1,000 days'
Amid conflicting reports about the need for vitamin E and how much is enough, a new analysis published today suggests that adequate levels of this essential micronutrient are especially critical for the very young, the elderly, and women who are or may become pregnant. (2014-09-15)

Filter bed substrates, plant types recommended for rain gardens
Researchers analyzed the effectiveness of three different filter bed substrates to support plant growth and remove nutrients from urban stormwater runoff. Twelve rain gardens containing 16 plant species were evaluated in the study. All three substrates reduced the quantity of pollutants in urban stormwater runoff. Substrates did not affect shoot or root growth of plants. Eleven of the species used grew well in the rain gardens and are recommended as rain garden plants. (2014-07-21)

Climate change provides good growing conditions for charcoal rot in soybeans
With over 100 diseases that can attack soybean crops, why would charcoal rot rise to the top of the most wanted list? University of Illinois scientists cite the earth's changing climate as one reason that more research is needed on the fungus that causes charcoal rot. (2014-07-09)

Vitamin E in canola and other oils hurts lungs
A large new study upends our understanding of vitamin E and ties increasing consumption of supposedly healthy, vitamin E-rich oils -- canola, soybean and corn -- to the rising incidence of lung inflammation and, possibly, asthma. The good news: vitamin E in olive and sunflower oils improves lungs. The study shows drastically different health effects of vitamin E depending on its form: gamma-tocopherol in soybean, canola and corn oil and alpha-tocopherol in olive and sunflower oils.

Sequencing hundreds of nuclear genes in the sunflower family now possible
Researchers have developed an efficient approach for sequencing hundreds of nuclear genes across members of the Compositae (sunflower family) to better-resolve phylogenetic relationships within the family, as well as a bioinformatic workflow for processing and analyzing the resulting sequence data. This method, available in the February issue of Applications in Plant Sciences, can be applied to any taxonomic group of interest and could serve as a model for phylogenetic investigations of other major plant groups.

"You hide it -- I'll find it!" -- Great tit has a bird's eye view when looking for dinner
Birds that hoard food for a rainy day better be sure that there are no great tits around to spy on where they hide their reserve of seeds and nuts. So say researchers, who found that great tits can remember the position of such hideaways up to 24 hours after seeing it cached. Interestingly, the great tits do not store up food themselves. The findings appear in Springer's journal Behavioral Ecology and Sociobiology. (2014-02-12)

EU policy is driving up demand for pollination faster than honeybee numbers
A new study indicates that demand for pollination services has risen five times as fast as the number of colonies across Europe. The findings indicate that, although the total number of honeybee colonies increased in some European countries, the demands for the pollination services supplied by these pollinators has increased much faster due to the increasing demand for biofuel feedstocks.

Oral allergy syndrome and high blood pressure medications can create lethal cocktail
Oral allergy syndrome sufferers that take high blood pressure medications may experience extreme facial swelling and difficulty breathing the next time they bite into a juicy apple.

Obesity rises in nearly all counties but Americans becoming more physically active
The rise in physical activity levels has had little impact so far on stopping the rising tide of obesity. As physical activity increased between 2001 and 2009, so did the percentage of the population considered obese. Obesity and risk factors from poor diets, smoking, and high blood pressure all are causing a drag on US life expectancies, which increased slowly compared to the country's economic peers between 1985 and 2010.

Vegetable oil IS good for you, MU researcher says
Since the 1970s, researchers have known that lineolic acid (LA) helps reduce blood cholesterol levels, and for decades, scientists have known that consuming LA can help lower the risk of heart disease. However, some experts have been claiming recently that Americans might be getting too much of a good thing. A new study from the University of Missouri contradicts that claim. (2013-06-07)

Improving 'crop per drop' could boost global food security and water sustainability
Improvements in crop water productivity -- the amount of food produced per unit of water consumed -- have the potential to improve both food security and water sustainability in many parts of the world, according to a study published online in Environmental Research Letters May 29 by scientists with the University of Minnesota's Institute on the Environment and the Institute of Crop Science and Resource Conservation at the University of Bonn, Germany.

Sacred lotus genome sequence enlightens scientists
The sacred lotus is a symbol of spiritual purity and longevity. Its seeds can survive up to 1,300 years, its petals and leaves repel grime and water, and its flowers generate heat to attract pollinators. Now researchers report that they have sequenced the lotus genome. Of all the plants sequenced so far -- and there are dozens -- sacred lotus bears the closest resemblance to the ancestor of all eudicots, a broad category of flowering plants that includes apple, cabbage, cactus, coffee and tobacco. (2013-05-10)

US a surprisingly large reservoir of crop plant diversity
North America isn't known as a hotspot for crop plant diversity, yet a new inventory has uncovered nearly 4,600 wild relatives of crop plants in the United States, including close relatives of globally important food crops such as sunflower, bean, sweet potato, and strawberry. (2013-04-29)

Replacing soybean meal in pig diets
Canola, cottonseed, and sunflower products can replace soybean meal in diets fed to pigs, but they contain less protein and energy. To determine if it makes economic sense to use them, producers need to know the concentrations and digestibility of the nutrients they contain. To help them make the decision, University of Illinois researchers examined amino acid digestibility for these products. (2013-02-28)

Corn could help farmers fight devastating weed
Researchers in China investigate corn's ability to act as a trap crop and control sunflower broomrape. (2013-01-07)

Role of omega-3 in preventing cognitive decline in older people questioned
Older people who take omega-3 fish oil supplements are probably not reducing their chances of losing cognitive function, according to a new Cochrane systematic review. Based on the available data from studies lasting up to 3.5 years, the researchers concluded that the supplements offered no benefits for cognitive health over placebo capsules or margarines, but that longer term effects are worth investigating. (2012-06-12)

Genetic mutation depicted in van Gogh's sunflower paintings revealed by scientists
In addition to being among his most vibrant and celebrated works, Vincent van Gogh's series of sunflower paintings also depict a mutation whose genetic basis has, until now, been a mystery.
