Biodiversity key to sustainable biofuel according to University of Minn. researcher's findings

...sts and prairies have been cleared to make way for agricultural fields planted with monocultures, buildings and roads. Tilman's research has shown that ecosystems containing many different plant species are more productive than those containing only one of those species. A return to biodiversity may prove to be ...

UC San Diego biologists solve plant growth hormone enigma

...e auxin is produced in the plant can be applied to agricultural problems, such as how to make seedless fruit or plants with stronger stems." Applying auxin to plants can have many different effects. For example, it can promote root development in cuttings, stimulate fruit development in the absence of fertiliz...

Mosquito spray increases toxicity of pyrethroids in creek, study finds

Wild bees and the flowers they pollinate are disappearing together

...ses of the declines are, although land use change, agricultural chemicals and climate change may be important factors. The researchers hope to clarify these issues with follow-up studies. Dr Biesmeijer said: "Whatever the cause, the study provides a worrying suggestion that declines in some species may trigger ...

Ammonia-loving archaea win landslide majority

...archers examined soil samples from 12 pristine and agricultural lands across three climatic zones to see if such ammonia-oxidizing microorganisms were present in terrestrial ecosystems as well. "We measured the abundance of the particular crenarchaeota gene alongside the same type of gene from bacteria," exp...

Basic work on E. coli identifies two new keys to regulation of bacterial gene expression

... variety of bacteria of medical, environmental and agricultural importance," notes Rick Gourse, a professor of bacteriology who published the Cell paper along with a team from his lab. "This knowledge can ultimately be put to use in systems that aren't so amenable to investigation, such as bacteria that cause cho...

Metal homeostasis research in plants will lead to nutrient-rich food and higher yielding crops

...trates such as Cadmium. Industrial, mining, and agricultural activities, particularly the excessive use of phosphate fertilizers, have led to high levels of Cadmium contamination at many locations worldwide. Utilizing DNA shuffling and heterologous expression in yeast, Guerinot and her colleagues isolated alle...

Salk scientists get to the root of plant cell fate

...r a plant cell to develop in ways that better suit agricultural needs. "If we know how a plant forms a root instead of a shoot, and that there is time in which to make such an important change, it might be possible to tell a plant to make a leaf instead of a flower," says the study's lead author, Jeffrey A. Lon...

Potato blight pathogenicity explained by genome plasticity

...ne of the 1840s and continues to cause devastating agricultural losses worldwide today. Infected plants are characterized by dark lesions on the stems, leaves, and tubers; damage to the tuber surface allows other fungi and bacteria to enter and destroy the core, often resulting in a foul odor. P. infestans is...

By discovering a root-knot nematode parasitism gene that's essential for the nematode to infect crops, the scientists have developed a resistance gene effective against all four species. Using a technique called RNA interference, the researche...

New biochip helps study living cells, may speed drug development
