Sunflowers move by the clock
Plant biologists at UC Davis and colleagues have discovered how sunflowers use their internal circadian clock, acting on growth hormones, to follow the sun during the day as they grow. Following the sun allows the plants to grow faster and put on more biomass. (2016-08-04)

New findings may explain the advantages of polyunsaturated fat
Previous research has demonstrated that saturated fat is more fattening and less muscle building than polyunsaturated fats. A new study shows that the choice of fat causes epigenetic changes which in turn could contribute to differences in fat storage. (2017-05-08)

UC team studies link between Parkinson's disease and depression
A patient who receives a diagnosis of Parkinson's disease might become depressed, and understandably so. But does the depression then exacerbate the progression of Parkinson's? That's one of the questions a team of University of Cincinnati researchers is studying, with the help of a $1.7 million grant from the National Institutes of Health. (2008-08-28)

UGA gets $2.5 million in grants to study plants to make biofuels
University of Georgia researchers were recently awarded two grants totaling $2.5 million to help find better ways to produce biofuels from switchgrass and sunflowers. (2008-08-07)

Scientists "scent train" honeybees to boost sunflowers' seed production
If you want a dog to hunt something down, it helps to let them sniff an item to pick up the scent. Now, researchers reporting in Current Biology on September 17 have found that scent training honeybees might work in a similar way--and that this approach could make bees more efficient in pollinating crops. The findings show that honeybees given food scented with sunflower odors led to a significant increase in sunflower crop production. (2020-09-17)

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)

Traces of early Native Americans -- in sunflower genes
New information about early Native Americans' horticultural practices comes not from hieroglyphs or other artifacts, but from a suite of four gene duplicates found in wild and domesticated sunflowers. Indiana University Bloomington scientists learned duplications of the gene flowering locus T, or FT, could have evolved and interacted to prolong a flower's time to grow. A longer flower growth period means a bigger sunflower -- presumably an attribute of value to the plant's first breeders. (2010-04-02)

Silicon's effect on sunflowers studied
As the popularity of sunflowers grows among commercial growers and everyday gardeners, scientists are looking for new supplements and growing methods to enhance production and quality of this celebrated annual. (2008-05-07)

Study suggests genetically modifying sunflowers for white mold resistance
A field study conducted by plant scientists at Vanderbilt University and Indiana University found that a transgene that can provide commercial sunflowers with additional protection against a disease called white mold is unlikely to spread throughout the wild sunflower population: Wild sunflowers already possess a degree of resistance to white mold and, as a result, those that pick up the transgene do not appear to gain a reproductive advantage that would cause them to spread widely. (2003-05-22)

Undergraduates uncover mechanism tied to plant height
Dwarfed plants add color and a diversity of architectures to landscapes and gardens, and a Purdue University undergraduate class discovered a key mechanism that leads to their small stature. (2016-08-08)

Diverse natural fatty acids follow 'Golden Mean'
Bioinformatics scientists at Friedrich Schiller University in Jena (Germany) have discovered that the number of theoretically possible fatty acids with the same chain length but different structures can be determined with the aid of the famous Fibonacci sequence. As they explain in Scientific Reports, the number of possible fatty acids with increasing chain length rises at each step by a factor of approximately 1.618, and therefore agrees with what is called the 'Golden Mean.'

Sheep thrive in GMO feeding trial
Increased wool growth and live weight gain in Merino sheep are the results of a recent Australian feeding trial using genetically modified lupins. The CSIRO trial explored nutritional benefits of lupin seeds genetically modified to incorporate a sunflower gene that stimulates the production of a highly nutritious protein. (2000-11-21)

Health risks through fumigated containers
Products transported by sea in containers are often fumigated with biocides as protection against pests. In addition to this, they often contain volatile organic solvents, such as the potentially carcinogenic 1,2-dichloroethane, which can originate from cleaning or manufacturing processes. In a meeting held at the German Federal Institute for Risk Assessment (BfR) on 16 November 2018, 36 experts from science, monitoring authorities, trade and industry discussed the effects of substances of this kind on health, along with the need for future action.

Extending the vase life of cut flowers: Pre-treatments and preservatives studied
A multiyear study identified patterns of postharvest responses to commercial hydrator and holding floral preservatives among 121 cultivars of specialty cut flowers. Cut stems were pretreated with either a commercial hydrating solution or deionized water, then placed in either a holding solution or deionized water. Particular combinations of preservatives and hydrating treatments were found to either increase or decrease vase life of the flowers. The study contains valuable information for flower growers, retailers, and consumers. (2011-07-01)

Low vitamin E intake during pregnancy can lead to childhood asthma

Cross-species mating may be evolutionarily important and lead to rapid change, say IUB researchers
A study of sunflower species that began 15 years ago shows that the sudden mixing and matching of different species' genes can create genetic super-combinations that are considerably more advantageous to the survival and reproduction of their owners than the gene combinations their parents possess. (2003-08-07)

Sticky business: Magnetic pollen replicas offer multimodal adhesion
Researchers have created magnetic replicas of sunflower pollen grains using a wet chemical, layer-by-layer process that applies highly conformal iron oxide coatings. The replicas possess natural adhesion properties inherited from the spiky pollen particles while gaining magnetic behavior. (2013-11-21)

Predicting the movement of genes
In a study published in the December issue of Ecological Applications, Charity Cummings (University of Kansas), Helen Alexander (University of Kansas), Allison Snow (Ohio State University), Loren Riesenberg (Indiana University) and colleagues tracked the movement of three specific alleles, or genes, in wild and domesticated sunflowers to determine how often and to what extent these plant populations will hybridize and pass specific genes on to the next generation. (2002-12-30)

Why food sticks to nonstick frying pans
Foods will sometimes get stuck to a heated surface, even if oil or a nonstick frying pan is used. Scientists have investigated the fluid properties of oil on a flat surface and their work shows convection may be to blame. When the pan is heated from below, a temperature gradient is established in the oil film, as well as a surface tension gradient. This gradient sets up a type of convection known as thermocapillary convection. (2021-02-02)

Scientists unravel ancient evolutionary history of photosynthesis
The origin of photosynthesis in green plants, on which all life on Earth depends for food and oxygen, has been a longstanding problem. By analyzing the genes of all species of photosynthetic bacteria, Indiana University biologists have unraveled the evolutionary history of photosynthesis. (2000-09-06)

A tough day could erase the perks of choosing 'good' fat sources, study finds

Mineral oil contamination in humans: A health problem?
From a quantitative standpoint, mineral oil is probably the largest contaminant of our body. That this contaminant can be tolerated without health concerns in humans has not been proven convincingly. The current editorial of the European Journal of Lipid Science and Technology reflects on this and concludes that this proof either has to be provided or we have to take measures to reduce our exposure from all sources, including cosmetics, pharmaceuticals and the environmental contamination. (2008-11-24)

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.

Baseball food and drink: Healthy chemistry scores a surprise hit
A baseball stadium may not be the first place that comes to mind when looking for healthy foods, but researchers are finding that ballpark favorites, including beer, are surprisingly good for moderation, of course. The American Chemical Society has compiled a brief report on healthy compounds found in stadium foods based on studies published in its Journal of Agricultural and Food Chemistry. (2005-07-07)

Effects of linoleic acid on inflammatory response depend on genes
The effects of linoleic acid on the human body are largely dependent on genes, a new study from the University of Eastern Finland shows. Linoleic acid is an essential fatty acid. People carrying different variants of the FADS1 gene had a different inflammatory response and different changes in their fasting glucose levels when supplementing their diet by linoleic acid rich sunflower oil. This was the first time these associations were studied in humans. (2019-01-15)

Pollinator-friendly flowers planted along with crops aid bumblebees
A new study reported this week by evolutionary ecologist Lynn Adler at the University of Massachusetts Amherst and Rebecca Irwin of North Carolina State University, with others, suggests that flower strips -- rows of pollinator-friendly flowers planted with crops -- offer benefits for common Eastern bumblebee (Bombus impatiens) colony reproduction, but some plants do increase pathogen infection risk. (2020-05-14)
