Researchers from Imperial College London and Queen Mary, University of London have created an online database that allows users to see flower colors through the eyes of a bee. The database, which is entitled the Floral Reflectance Database (FReD), is referenced in the latest edition of the journal PLoS One as "a valuable new tool for researchers interested in the colors of flowers and their association with pollinator color vision, containing raw spectral reflectance data for a large number...

Two proteins involved in powdery mildew infection in plants also play an important role in fertilisation Mildew infections not only cause unsightly vegetable patches, they can also result in extensive crop failure. Interestingly, the processes involved in infections with this garden pest are similar to those involved in fertilisation. Scientists from the Max Planck Institute for Plant Breeding Research in Cologne and the University of Zurich have identified two proteins in the model plant...

The seeds that you plant in your backyard garden next spring "” and farmers sow in their fields "” may have a guardian angel that helps them sprout, stay healthy, and grow to yield bountiful harvests. It's a thin coating of chemicals termed a "seed treatment" that can encourage seeds to germinate earlier in the season, resist insects and diseases, and convey other advantages. These new seed defenders are the topic of an article in the current issue of Chemical & Engineering...

"How do hearts, wings or flowers get their shape?" asks Professor Enrico Coen from the John Innes Centre. " Unlike man-made things like mobile phones or cars, there is no external hand or machine guiding the formation of these biological structures; they grow into particular shapes of their own accord." "Looking at the complex, beautiful and finely tuned shapes produced by nature, people have often wondered how they came about. We are beginning to understand the basic genetic and chemical...

Plants that can pollinate themselves are more likely to go extinct, says new study of nightshade plant family Many plants can pollinate themselves and reproduce without the aid of a mate, thanks to having both male and female parts. But the short-term perks of being able to go it alone come with long-term costs, says a new study in the journal Science. The reason is because plants that can pollinate themselves are more prone to extinction, scientists say. Flowering plants are incredibly...

Mechanical properties of explosive seed dispersal in Cardamine Catapults are often associated with a medieval means of destruction, but for some plants, they are an effective way to launch new life. Dispersing seeds greater distances by catapulting can provide selective advantages, including the establishment of populations in new environments and escape from certain threats. In new work published in the recent October issue of American Journal of Botany, Dr. Ellerby, students, and...

High in an alpine meadow, Gesine Pufal, from the University of Wellington, New Zealand, crouched low to the ground and splashed some water from her water bottle on a low green plant cushion, then sat back waiting to see if something would move. Sound crazy? Many hikers passing by her may have thought so, but Pufal was trying to find potential plant species that possess a type of plant movement called hygrochasy. Although the ability to move is typically thought to be a characteristic unique...
