Researchers find gene that may be at root of potato blight
Researchers have found a gene they suspect plays an important role in triggering the blight that wiped out Ireland's potato crops a century-and-a-half ago. The scientists describe the gene, called Avr3a, in a study...15 generations of untrained jocks, couch potatoes show big physiological adaptations
So, you don't like to exercise? Maybe you could blame it on your great-great-grandparents. Similarly, if you're a practiced and proud couch potato who suddenly woke up to the fact that you're a "natural" athlete, the credit could also belong to your genes. Exercise research traditionally has focused on the effects of training, rather than underlying genetic mechanisms. But physiologists wo...Finding rewrites the evolutionary history of the origin of potatoes
Humans have cultivated potatoes for millennia, but there has been great controversy about the ubiquitous vegetable's origins. This week, writing in the Proceedings of the National Academies of Sciences, a team led by a USDA potato taxonomist stationed at the University of Wisconsin-Madison has for the first time demonstrated a single origin in southern Peru for the cultivated potato. The s...Malaria, potato famine pathogen share surprising trait
Two wildly different pathogens ?one that infects vegetables, the other infecting humans - essentially use the same protein code to get their disease-causing proteins into the cells of their respective hosts. That's what researchers from Ohio State and Northwestern universities report in a study published in the current issue of the journal PLoS Pathogens. The scientists were surprised to l...Potato blight pathogenicity explained by genome plasticity
A team of researchers from Wageningen University report in this month's issue of that they have identified a unique genetic fingerprint in the pathogen responsible for potato blight. Some strains of the pathogen possess multiple copies of a specific gene, while other strains possess only a single copy. Certain potato plants do not recognize strains of the pathogen with on...Anti-Acid Phosphatase, Potato Polyclonal Antibody, Unconjugated from CHEMICON
Description:Acid phosphatase (Potato). Monospecific by IEP. Some cross reactivity between Acid phosphatases of other species may occur....Inoculation of Viral RNA and cDNA to Potato and Tobacco Plants Using the Helios Gene Gun
Tuija Kekarainen and Jari P. T. Valkonen, Department of Plant Biology, SwedishUniversity of Agricultural Sciences (SLU), P.O. Box 7080, SE-75007 Uppsala, Sweden Particle bombardment is a physical method widely used for gene transfer into plants, mammals, fungi and bacteria (Armaleo et al. 1990, Klein et...Potato powder to stop bleeding
Researchers from Mayo clinic study that a potato-based powder holds potential for the treatment of everything from minor cuts to surgical incisions, and may even combat injuries. Hemostat, a blood-clotting agent,produces immediate coagulation at the surface of a wound, followed by the normal blood-clotting processes.// The powder-based coagulant may one day help anesthesiologists limit bleeding d...Slimmer’s Delight: Potato Version 2, on a platte
Kudos to scientists who have discovered low calorie potatoes, giving spuds, another potato variety, a run for its money! Vivaldi, the new age potato, signals the arrival of potatoes that significantly taste better with nearly half the calories of spuds. Talk of Health choices in ubiquitous potatoes!// Vivaldi was the result of a lot of hard work and research for nine long years. Allie...A potato (couch or not) in the diet adverse for diabetics.
'Potato-potato' burning bright in the hands of you could predispose you to an elevated risk of type 2 diabetes.According to a long-term study of nearly 85 000 United States women Harvard University researchers’ //found that those with the highest potato intake had a modestly elevated risk of developing type 2 diabetes. Obese women, who are already at increased risk of the disease,...A new disease: couch potato: needs drug therapy
Couch potato is a layman word for “Extreme laziness” which is a medical condition called motivational deficiency disorder (MoDeD). This was told by Australian researchers in a report in the 1 April issue of the British Medical Journal (BMJ) // Professor Leth Argos, a neuroscientist at the University of Newcastle, reportedly identified the new disorder. In severe cases it can be fatal b...Repeated Weight loss Messages Have No Effect On Couch Potatoes
The obsession of the media as well as the society of having slim bodies may not be enough motivation for couch potatoes to get up and exercise// , according to a UCLA study. In fact the repeated stress on weight loss may make obese people more determined to spend time doing nothing, the study said. Published in the June edition of the peer-reviewed journal Obesity, the cross-cultural s...
