A cellulose powder has been used increasingly for many years against allergic rhinitis. Still, there has been a shortage of scientific evidence for its efficacy in seasonal allergic rhinitis (hay fever), particularly in children. Now, however, scientists from the Sahlgrenska Academy and the Department of Plant and Environmental Sciences at the University of Gothenburg have proven that the cellulose powder reduces symptoms of seasonal allergic rhinitis in children, without any adverse...

A team of researchers at the Instituto Gulbenkian de Ciência (IGC), Portugal, discovered that pollen, the organ that contains the plant male gametes, communicate with the pistil, their female counterpart, using a mechanism commonly observed in the nervous system of animals. This study not only reveals a new mechanism which underlies reproduction in plants, but also opens an exciting new avenue in the study of how cell-cell communication is conserved between animals and...

The longer days and warmer weather are not only a sign that spring has sprung, but also a signal that allergies are in full bloom. Doctors at Baylor College of Medicine have a few tips on how to get through the season. "As the weather gets warmer and humid we see increasing levels of tree pollen, followed by grass pollen and to some degree mold spores later in the season," said Dr. Madhu Narra, assistant professor of medicine in the section of allergy, immunology and rheumatology at Baylor...

A new University of Florida study of 45-million-year-old pollen from Pine Island west of Fort Myers has led to a new understanding of the state's geologic history, showing Florida could be 10 million to 15 million years older than previously believed. The discovery of land in Florida during the early Eocene opens the possibility for researchers to explore the existence of land animals at that time, including their adaptation, evolution and dispersal until the present. Florida Museum of...

Warmer temperatures and later autumn frosts have been the main sources for why the ragweed allergy season in North America has grown two to four weeks longer than usual, according to researchers. Northern regions of the United States and Canada have seen a dramatic rise in the length of the allergy season between 1995 and 2009, said researchers, who published a report in Tuesday's issue of the Proceedings of the National Academy of Sciences. Saskatoon, in Saskatchewan, Canada had the...

Study uncovers genetic hierarchy in plant sperm formation Biologists at the University of Leicester have published results of a new study into the intricacies of sex in flowering plants. They have found that a gene in plants, called DUO1, acts as a master switch to ensure twin fertile sperm cells are made in each pollen grain. The research identifies for the first time that DUO1 switches on a battery of genes that together govern sperm cell production and their ability to produce seeds.. The...

Many plants produce toxic chemicals to protect themselves against plant-eating animals, and many flowering plants have evolved flower structures that prevent pollinators such as bees from taking too much pollen. Now ecologists have produced experimental evidence that flowering plants might also use chemical defenses to protect their pollen from some bees. The results are published next week in the British Ecological Society's journal Functional Ecology. In an elegant experiment, Claudio...

Scientists have discovered why orchids are one of the most successful groups of flowering plants - it is all down to their relationships with the bees that pollinate them and the fungi that nourish them. The study, published tomorrow in the American Naturalist, is the culmination of a ten-year research project in South Africa involving researchers from Imperial College London, the Royal Botanic Gardens, Kew, and other international institutions. The orchid family is one of the largest groups...
