Researcher finds alternatives to antibiotics for growing chickens
...odies and CLA, rather than antibiotics, will allow breeders
to select for animals with stronger immune systems, according to Cook. That would lead to animals better able to fight off infections on their own, thus further decreasing the need for antibiotics to treat sick birds....
Genetic extremism overstates risks
...eeding for hundreds of years," Strauss said. "When breeders
attempt to introduce new traits via breeding, or attempt to develop a crop for a new environment, there are many bumps along the road as the varieties and technology are refined. This is very similar to the early stages of genetic engineering." "The ...
Clemson University delivers healthy mares and foals
...Aside from the investment aspect,both professional breeders
and private individuals want to protect thehealth and well-being of their horses. "We studied the cellular action of the alkaloids produced by thefungus-infected fescue grass," Cross said. "The alkaloids were activatingdopamine receptors that...

Research Bears Fruit, And Patents
... Scottish Crop Research Institute in 1989, and the breeders
at the USDAhelped me develop my breeding philosophies. Derek and I established geneticengineering protocols for raspberries and blackberries. He helped me raise thescope and depth of our program to what it is today." The researchers' objec...
Summer Science: Where Have All The Honeybees Gone? UD 'Bee Guy' Asks Why--From
America To The Amazon
... Italian species. Well-meaning South American bee breeders
also brought the Africanized or"killer" bee to Brazil, Caron says. And, the varroa mite may have hitched a ridefrom Japan to South America, then hopped on the backs of bees headed for theUnited States, appearing in the United States in 1987. "Our bee...
'Mean Gene' Found In Africanized Honey Bees
...version of stinging genes so it will be easier for breeders
to avoid using these queen bees," he says. "Ultimately it might be possible to clone the gene through map-based cloning so that we can better understand how this gene affects stinging behavior. "We made a genetic map of the honey bee using the same t...
'Suicide Response' Gives Colorado State Researchers Important Clues On Preventing Bacterial Invasion In Crops Worldwide
... in plants exposed togram-positive bacteria. Plant breeders
have successfully engineered plantsresistant to diseases caused by gram-negative bacteria, which has been a focusof research for a number of years. But gram-positive bacteria have remained amystery, in part because they are difficult to grow in a lab...

Pea Plant Stem Growth Gene Cloned
... a review of the conference showed that many plant breeders
had never heard of Mendel or his experiments. They were excited by the "new" findings and soon put theory into practice. From these humble beginnings, genetics and later molecular biology, evolved. "Mendel's experiments are now included in every h...
Wild Plant Genes Increase Food Production
...ion. Before the availability of molecular markers, breeders
had no way of finding the genes from the wild species because there was no way to identify the functions of genes controlling complex (or quantitative) traits in any species. The researchers have genetically mapped rice and made the information avail...
First Salmonella Vaccine For Poultry To Be On The Market Soon
... When given a dose of the vaccine, newborn chicks, breeders
and laying hens develop a lifelong immunity to salmonella. The immunity is transferred to offspring and eggs that people consume. The vaccine is in its final stage of testing by scientists at Megan Health Inc. in St. Louis, a company licensed by Wa...

Purdue Researchers Prod Plants To Clean Up Pollution
...rabidopsis could be applied to other plants. Once breeders
develop metal-mining plants, EPA Superfund-site farmers might clean up contaminated sites after a few cropping seasons. The same DNA responsible for a plant's ability to pull toxic metals from soil could be manipulated to coerce carrot, corn, apple o...
