Allergy Free Plants On The Horizon?
2012-09-01 07:44:57

redOrbit Staff & Wire Reports - Your Universe Online Those who love gardening, or just enjoy the beauty of plant life, but are unable to do so as a result of hay fever or similar allergic reactions will undoubtedly welcome new research out of Spain that could result in long-lasting, pollen-free plants. According to an August 30 statement, researchers from the Instituto de Biología Molecular y Celular de Plantas (IBMCP) and BIOMIVA S.L. were able to alter an ornamental...

FIVE POINTS, Calif., Aug 22, 2012 /PRNewswire/ -- S&W Seed Company (Nasdaq: SANW) today announced it has purchased the rights to a portfolio of alfalfa varieties suited for colder climate conditions, thereby expanding its alfalfa genetics to include dormant varieties. Since 1980, S&W has focused on breeding and producing non dormant alfalfa seed, known as 8, 9 and 10 dormancies that are suited to warm climates. This purchase is the first time the company has ventured into seed...

Rodents Do Their Part To Help Save Tropical Trees
2012-07-17 06:07:04

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online There's no honor among thieves when it comes to rodent robbers – which turns out to be a good thing for tropical trees that depend on animals to spread their seeds, according to recent research. Big seeds produced by many tropical trees were probably once ingested and then defecated whole by huge mammals called gomphotheres that dispersed the seeds over large distances. But gomphotheres were...

Research pinpoints how plants know when to flower
2012-05-28 06:11:52

Scientists believe they've pinpointed the last crucial piece of the 80-year-old puzzle of how plants "know" when to flower. Determining the proper time to flower, important if a plant is to reproduce successfully, involves a sequence of molecular events, a plant's circadian clock and sunlight. Understanding how flowering works in the simple plant used in this study — Arabidopsis — should lead to a better understanding of how the same genes work in more complex plants grown...

How Flowers Pollinate With Precision
2012-05-17 11:25:35

Next Mother's Day, say it with an evolved model of logistical efficiency – a flower. A new discovery about how nature's icons of romance manage the distribution of sperm among female gametes with industrial precision helps explain why the delicate beauties have reproduced prolifically enough to dominate the earth. In pollination, hundreds of sperm-carrying pollen grains stick to the stigma suspended in the middle of a flower and quickly grow a tube down a long shaft called a style...

Birds Cultivate Decorative Plants To Attract Mates
2012-04-23 10:35:51

An international team of scientists has uncovered the first evidence of a non-human species cultivating plants for use other than as food. Instead, bowerbirds propagate fruits used as decorations in their sexual displays. The researchers discovered male bowerbirds had unusually high numbers of fruit-bearing plants growing around their bowers, and used these fruits in order to attract females. Published today (24 April), in Current Biology the research was carried out by the Universities of...

When unproductive plants were given the working protein, their flowering time was restored Flowering is the most crucial act that plants undergo, as the fruits of such labor include crops on which the world depends, and seeds from which the next generation grows. While classic experiments have demonstrated that plants are able to adjust the timing of their flowering in response to environmental conditions, such as light, temperature and the availability of nutrients, very little has...

Flowering is the most crucial act that plants undergo, as the fruits of such labor include crops on which the world depends, and seeds from which the next generation grows. While classic experiments have demonstrated that plants are able to adjust the timing of their flowering in response to environmental conditions, such as light, temperature and the availability of nutrients, very little has been known about what exactly triggers plants to make flowers instead of leaves, under various...

Seed size is controlled by small RNA molecules inherited from a plant's mother, a discovery from scientists at The University of Texas at Austin that has implications for agriculture and understanding plant evolution. "Crop seeds provide nearly 70 to 80 percent of calories and 60 to 70 percent of all proteins consumed by the human population," said Z. Jeff Chen, the D.J. Sibley Centennial Professor in Plant Molecular Genetics at The University of Texas at Austin. "Seed production is...

Plants Mimic Scent Of Pollinating Beetles
2012-04-04 03:33:16

The color and scent of flowers and their perception by pollinator insects are believed to have evolved in the course of mutual adaptation. However, an evolutionary biologist from the University of Zurich has now proved that this is not the case with the arum family at least, which evolved its scent analogously to the pre-existing scents of scarab beetles and thus adapted to the beetles unilaterally. The mutual adaptation between plants and pollinators therefore does not always take place....

Iris is a genus of flowering plants with showy flowers ranging in color from gold, copper-red or yellow to white, blue, blue-violet, lavender, tan, maroon and purple. Pink and apricot colored irises have also been bred in some species. The name "Iris" can be applied to the genus or to any of the species within it. It is also applied to various subdivisions within the genus. Description There are many species of iris widely distributed throughout the northern temperate zone. Their...
