Balancing male fertility and disease resistance
May 08, 2006An international collaboration of researchers, headed by Dr. Shiping Wang (Huazhong Agricultural University, China) has discovered that a single gene in rice regulates both male fertility and pathogen resistance, providing an unexpected genetic link between reproductive success and the disease resistance.
Dr. Wang and colleagues characterized a new disease resistance (R) gene in rice, xa13, whose expression tips the balance between fertility and pathogen defense. The recessive xa13 allele provides resistance to bacterial leaf blight, the most devastating bacterial plant disease in the world. While expression of the dominant Xa13 allele makes plants more susceptible to disease, it also promotes pollen development. This surprising positive effect of Xa13 on plant fertility helps explain how an apparently detrimental allele has remained in the plant's gene pool.
Dr. Wang is confident that "the finding of multiple roles played by the same gene provided new perspective on relationships between the processes of disease resistance and sexual reproductive development, which will greatly influence our way of thinking in future studies."

Disease Resistance Current Events and Disease Resistance News RSSIowa State University researcher discovers key to vital DNA, protein interaction
A researcher at Iowa State University has discovered how a group of proteins from plant pathogenic bacteria interact with DNA in the plant cell, opening up the possibility for what the scientist calls a "cascade of advances."
UCR researchers develop genetic map for cowpea, accelerating development of new varieties
Cowpea, a protein-rich legume crop, is immensely important in many parts of the world, particularly drought-prone regions of Africa and Asia, where it plays a central role in the diet and economy of hundreds of millions of people.
Coral bleaching increases chances of coral disease
Mass coral bleaching has devastated coral colonies around the world for almost three decades. Now scientists have found that bleaching can make corals more susceptible to disease and, in turn, coral disease can exacerbate the negative effects of bleaching.
Draft potato genome based on unique potato variety
The Potato Genome Sequencing Consortium (PGSC), an international team of scientists from industry and academia in 14 countries, has released a draft sequence of the potato genome with the help of a Virginia Tech researcher.
MSU scientist helps map potato genome; move will improve crop yield
It's been cultivated for at least 7,000 years and spread from South America to grow on every continent except Antarctica. Now the humble potato has had its genome sequenced.
Melon research sweetened with DNA sequence
People smell them, thump them and eyeball their shape. But ultimately, it's sweetness and a sense of healthy eating that lands a melon in a shopper's cart.
Plant protein 'doorkeepers' block invading microbes, study finds
A group of plant proteins that "shut the door" on bacteria that would otherwise infect the plant's leaves has been identified for the first time by a team of researchers in Denmark, at the University of California, Davis, and at UC Berkeley.
Variation in the same gene affects rate of parasite infection in both humans and baboons
Researchers at the Duke University Institute for Genome Sciences & Policy have found that variation in the same gene in humans and baboons produces the same kind of disease resistance.
Bovine genome provides clues to possible new developments
Scientists from Texas AgriLife Research and the Texas A&M University College of Veterinary Medicine & Biomedical Sciences (CVM) are part of a consortium of researchers who have developed an annotated sequence of the cattle genome which could lead to better disease resistance and higher quality meat for consumers, the researchers say.
New wheat disease could spread faster than expected
Both plant and human diseases that can travel with the wind have the potential to spread far more rapidly than has been understood, according to a new study, in findings that pose serious concerns not only for some human diseases but also a new fungus that threatens global wheat production.

The Metabolic Syndrome Program: How to Lose Weight, Beat Heart Disease, Stop Insulin Resistance and More by Karlene Karst (Author) Big Belly? High Body Mass Index? High Blood Pressure? If this sounds like you, you may be one of the millions of North Americans with Metabolic Syndrome. Predicted by medical experts as the likely number one risk factor for heart disease-Metabolic Syndrome, or MSX, describes a constellation of conditions, including those mentioned above, of which the body' resistance to insulin is a primary feature. A byproduct of obesity, 25 percent of the adult U.S. population is now estimated to have MSX. The Metabolic Syndrome Program offers readers a sensible lifestyle-based approach to treating MSX. One of the first books to name and address this condition, The Metabolic Syndrome Program outlines a realistic plan of treatment-without magic pills or quick-fixes to a growing and... |

Insulin Resistance: Childhood Precursors and Adult Disease (Contemporary Endocrinology) by Philip S. Zeitler (Editor), Kristen J. Nadeau (Editor) The prevalence of disorders related to insulin resistance has continued to increase throughout the developed and developing world. The world’s population has continued to become more obese and sedentary. Of great concern in the last decade is the extension of these deleterious lifestyle patterns to the pediatric population, leading to both obesity and the appearance of insulin resistance-related disorders in youth as well as adults. Insulin Resistance: Childhood Precursors and Adult Disease presents topics related to insulin resistance and its consequences across the lifespan. In the first section of the book examining epidemiology, the contributors review controversies over the definition of metabolic syndrome in adults and children, current knowledge regarding the epidemiology of... |

Panax Ginseng Root in Extract 8.8 oz by Chinese Imports Panax ginseng can boost the immune system, and therefore increase resistance to disease. It may increase physical stamina, and stimulate the appetite, which can be especially useful for the elderly. It may improve the memory, and several studies have indicated that American ginseng reduces total blood cholesterol levels. It has an anti-clotting action that may reduce the risk of heart attacks. American ginseng may also be used by diabetics to reduce blood sugar levels, though not before consulting a qualified healthcare professional. |

Diabetes: Managing a 21st Century Lifestyle Disease (NCME Video 769) Also With: Network For Continuing Medical Education (Primary Contributor), Gerald Bernstein (Primary Contributor) Diabetes mellitus affects nearly 6% of the U.S. population, making it one of the most common medical problems seen by physicians. Each year, diabetes costs the nation nearly $100 billion in treatment and disability. Preventing complications, such as kidney failure, cardiovascular disease, blindness, and nerve damage, is an important component of regular care. Equally critical to successful treatment is effective patient selfmanagement and education. Often, this means a coordinated and collaborative healthcare effort. Dr. Bernstein reviews the rising prevalence and pathophysiology of diabetes, including the disturbing rise in Type 2 diabetes among children. In addition, he discusses how associated syndromes, such as insulin resistance, are joining diabetes as major lifestyle diseases of... |
