Synthetic photoreceptor stimulates germination and development irrespective of exposure to light; results of researchers from Japan and Karlsruhe are published in the Plant Cell journal Plants are dependent on the sun. Sunlight does not only supply them with energy, but also controls their development steps. So-called photoreceptors activate the processes of germination, leaf development, bud formation, and blossoming in the cells. The light-absorbing component of a photoreceptor may be...

The Absence Of Elephants And Rhinoceroses Reduces Biodiversity In Tropical Forests
2012-05-11 08:52:07

The progressive disappearance of seed-dispersing animals like elephants and rhinoceroses puts the structural integrity and biodiversity of the tropical forest of South-East Asia at risk. With the help of Spanish researchers, an international team of experts has confirmed that not even herbivores like tapirs can replace them. "Megaherbivores act as the 'gardeners' of humid tropical forests: They are vital to forest regeneration and maintain its structure and biodiversity", as was explained...

Soybeans soaking in warm water could become a new "green" source for production of a cancer-fighting substance now manufactured in a complicated and time-consuming industrial process, scientists are reporting in ACS' Journal of Agricultural and Food Chemistry. Hari B. Krishnan and colleagues explain that the substance, Bowman-Birk Protease Inhibitor (BBI), has shown promise for preventing certain forms of cancer in clinical trials. Those human tests resulted from evidence of BBI's...

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...

University of Alberta researcher Christina Engels has discovered how to extract a compound from mustard seeds that can protect against food spoilage. Engels recovered a particular compound–sinapic acid–from mustard seed meal, which shows antibacterial effects against such strains as Staphylococcus aureus, E. coli and Listeria monocytogenes, all of which can cause grave illness and death in humans. Canada is the world's largest exporter of mustard seed. The results published...

New research reveals Artemisia tridentata seeds can form a persistent seed bank, ensuring its survival in an invasive, fire-prone system Big sagebrush (Artemisia tridentata) is a key foundational species in an ecosystem that is threatened by invasion of cheatgrass and the subsequent increase in fire frequency. Critical to the conservation, reestablishment, and restoration of the sagebrush steppe ecosystem (which comprises 63 million hectares of the Great Basin of North America) is...

Noise Pollution Has Effect On Plants, Study Finds
2012-03-23 06:50:06

A new study published in the Proceedings of the Royal Society B has found that human noise like traffic can have ripple effects on plants. Lead author Clinton Francis of the National Evolutionary Synthesis Center (NESCent) in Durham, North Carolina, said the consequences of noise could last for decades, even after the source of the noise goes away. Previous studies found that some animals increase in numbers near noisy sites, while others decline, but the results of the new study found...

Recalcitrant seeds
2013-08-21 08:52:36

Recalcitrant seeds are seeds that have to be protected from certain elements, such as drying and freezing, to remain viable. Seeds must be maintained at temperatures no less than 50 degrees Fahrenheit and does not have long shelf lives. Damage to the seeds results when they are allowed to dry out excessively, damaging the intracellular structures of the seeds, along with the forming of toxic chemicals within the seed. Recalcitrant seeds can be found in avocado, mango, cocoa and the...

Seed bank
2013-07-31 15:37:35

Seed banks are gene pools of seeds from food crops and other rare species. If seeds from the reserves are destroyed, seeds from seed banks can be used to generate new crops. Seed banks are not open to the public as are seed libraries or seed swaps. Maintaining seeds in a seed bank will preserve the seeds during times of natural disasters, disease outbreaks, or even war. SEED DORMANCY Seeds can remain dormant for decades as long as the storage environment remains cool and dry. Seeds that...

Seed Drilling
2013-05-18 07:39:11

Seed drilling is a method used by farmers in order to have a more unified, crop-yielding season. The first known use of seed drilling was in 1500 BC by the Sumerian. At this time, they were using a single tube. Later, in the 2nd Century BC, the Chinese developed a multi-tube iron drill. This facilitated in a larger crop planting allowing them to feed their large population. The first recorded patent of a sowing machine was in 1566 by the Venetian Senate, attributing Camillo Torello. In the...

Seed Saving
2013-05-18 07:22:11

Seed saving is the preserving of seeds from mature vegetables, herbs, and flowers used in subsequent years along with bulbs and tubers. Home gardeners have saved seeds for generations and the practice is now becoming common with organic farmers as well as permaculturists. Growers will clone plants so as not to produce seeds keeping the plant “true to type” to the parent plant. True to type refers to the characteristics of the parent plant such as large fruit/blooms. Plants...

Biennial Plant
2013-04-27 07:50:37

Biennial plants have a two year life cycle; roots, stems and leaves in the first year with flowers following the next year after a cold winter dormant period. Biennials will produce seed and fruit before dying. There are not as many biennial plants as there are perennials or annuals. Biennial plants, when exposed to extreme climate conditions, may have a shortened life cycle of a few months especially if the plants were exposed to colder than normal temperatures. Most biennials can be...
