Biologists from Harvard University recently examined why the flowers of lilies have characteristically crinkled edges. PhD student Haiyi Liang and Professor L. Mahadevan carried out the research. The lily was marked with dots along the edge of the petal as well as the center of the flower. Time-lapse video reveals that the petals grow longer at the edges than in the middle. These dots enabled the researchers to measure every physical change of the flower as it grew from bud to bloom. "I...

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...

Research provides good news for stone fruit growers Blossom or fruitlet thinning is a labor-intensive part of commercial peach and nectarine production. The use of mechanical string blossom thinners has been shown to reduce labor requirements and improve fruit size in peach crops, but stone fruit producers have needed more information about the range of thinning times. New research from Tara Auxt Baugher and colleagues from The Pennsylvania State University and Penn State Cooperative...

A million-dollar question Sleeping Beauty's kingdom was overgrown by vines when she fell into a deep sleep. Researchers at the Smithsonian in Panama and the University of Wisconsin at Milwaukee received more than a million dollars from the U.S. National Science Foundation to discover why real vines are overtaking the American tropics. Data from eight sites show that vines are overgrowing trees in all cases. "We are witnessing a fundamental structural change in the physical make-up of forests...

A Los Angeles photographer has developed a technique to create extremely detailed images of flowers. Using technology used by NASA on Mars, David Leaser's innovative Nightflowers collection shows large scale botanicals with such detail you can literally see the pollen glistening on the stamens. The images have attracted the attention of Architectural Digest, and they will be introduced at their 10th Anniversary Home Design Show on March 17 in New York City. Los Angeles, CA (PRWEB) February 8,...

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...

Mechanism of spring-loaded seed launch discovered Even by invading plants' standards, the filaree, or common stork's bill, has been remarkably successful. Introduced into North America in the eighteenth century, it is now endemic in south-western states such as California, and the plant's intriguing seed dispersal mechanism seems to lie at the root of their success. Having launched as far as possible from the mother plant, the seed drills itself into the ground by repeatedly curling and...
