"A-Maize-ing" Discovery Could Lead to Higher Corn Yields
Genetics Society of America

Scientists may have made a discovery that could lead to higher corn yields in the United States. In research published in the March 2010 issue of the journal GENETICS, scientists used tropical maize from Mexico and Thailand to discover chromosome regions responsible for detecting seasonal changes in flowering time. This discovery may lead to higher crop yields, improved disease resistance, and heartier plants able to withstand severe weather.

Scientists Make Important Step Toward Stopping Plaque-Like Formations in Huntington’s Disease
Genetics Society of America

They might not be known for their big brains, but fruit flies are helping to make scientists and doctors smarter about what causes Huntington’s disease and how to treat it. New research, published in the journal GENETICS describes a laboratory test that allows scientists to evaluate large numbers of fruit fly genes for a possible role in the formation of plaque-like protein aggregates within cells. Those genes often have counterparts in humans, which might then be manipulated to stop or slow the formation of plaque-like protein aggregates, the hallmark of Huntington’s and several other neurodegenerative diseases.

Want to Slow Aging? New Research Suggests It Takes More than Antioxidants
Genetics Society of America

Don’t put down the red wine and vitamins just yet, but if you’re taking antioxidants because you hope to live longer, consider this: a new study published in the June 2010 issue of the journal GENETICS casts doubt on the theory that oxidative stress to our tissues shortens lifespan. That’s because researchers from McGill University in Canada have identified mutations in 10 different genes of worms (genes believed to have counterparts in humans) that extend their lifespan without reducing the level of oxidative stress the worms suffer. The results contradict the popular theory that production of toxic reactive oxygen species in tissues is responsible for aging.

Why Fad Diets Work Well for Some, but Not Others
Genetics Society of America

Research published in the journal GENETICS suggests that genetic interaction with diet primarily determines variations in metabolic traits such as body weight, as opposed to diet alone.

Fruit Flies Help Sniff Out New Insect Repellents
Genetics Society of America

Research by Yale scientists, published in the journal GENETICS, identifies pieces of control DNA that turn on or off genes that allow fruit flies to differentiate between smells, paving the way for better insect repellents.

Scientists Solve Mystery of Arsenic Compound
Genetics Society of America

Hopkins, Baylor and Stanford scientists identify a protein folding machine in yeast cells that controls the folding of other important “machines” that power cells, as a target for arsenite, an arsenic compound and common water contaminant.

"Green Genes" in Yeast May Boost Biofuel Production
Genetics Society of America

An effort to increase biofuel production has led scientists to discover genes in yeast that improve their tolerance to ethanol, allowing the production of more ethanol from the same amount of nutrients. This study shows how genetically altered yeast cells survive higher ethanol concentrations, addressing a bottleneck in the production of ethanol from cellulosic material (nonfood plant sources) in quantities that could compete economically with fossil fuels.

Attention Ladies and Gentlemen: Courtship Affects Gene Expression
Genetics Society of America

Scientists from Texas have made an important step toward understanding human mating behavior by showing that certain genes become activated in fruit flies when they interact with the opposite sex. This research shows that courtship behaviors may be more influenced by genetics than previously thought. Understanding why and how these genes become activated may also lead to insight into disorders such as autism.

New Model Reveals Pesticide-free Method to Control Mosquito-borne Disease
Genetics Society of America

Two strategies to control mosquito-borne diseases, such as malaria and dengue fever, are reducing mosquito population sizes or replacing populations with disease-refractory varieties. Scientists have modeled a genetic system that may be used for both, without the use of pesticides. This research was published in the February 2011 issue of Genetics.

Scientists Identify and Compare Yeast Genomes
Genetics Society of America

A team of U.S. researchers has identified and compared the genetic codes for all known species of yeasts closely related to bakers’ and brewers’ yeast, which lays the foundation for future understanding of mutation and disease, as studies of yeasts often identify key genes and mechanisms of disease.
