An insidious fuzzy gray mold that often coats refrigerated strawberries and many other plants during growing and storage may be prevented by a gene identified by a Purdue University researcher.
Purdue researcher Tesfaye Mengiste has identified the gene responsible for causing a fuzzy, gray mold that attacks fruits, such as strawberries and tomatoes. Mengiste, an assistant professor in the botany and plant pathology department, says gray mold disease destroys about 25 percent of the tomato and strawberry crop during some seasons.

The mold is caused by a fungus, Botrytis cinerea, that often enters plant tissue through wounded or dead areas such as wilted petals, bruised fruit or at the site of pruning. In the November issue of the journal The Plant Cell, Purdue plant molecular biologist Tesfaye Mengiste and his colleagues at Syngenta Biotechnology Inc. report that the gene, called BOS1, is the first protein identified that regulates plant response to both biological and non-biological stresses.
"Botrytis affects many important crops in the field, in the greenhouse and in post-harvest situations," said Mengiste, an assistant professor in the Department of Botany and Plant Pathology. "It attacks flowers, fruits, vegetables, bulbs, leaves and stems. It has a tremendous capacity to inflict disease and eventually cause loss of quality and yield."

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
