For Better Or Worse: Links Between Genetics And Stress

By Diane Nelson

Our genes can influence how we respond to stress. Science shows that some people are more genetically predisposed than others to develop depression and anxiety in response to stressful situations.

UC Davis psychologists Johnna Swartz (left) and Jay Belsky have found that genetic traits that make people vulnerable to stress-related mental health problems, are also those best equipped to respond to positive interventions.

What’s more, researchers say that chronic exposure to stressful conditions—such as poverty, family discord, and poor nutrition—can alter the way genes behave in children and adolescents, making them more susceptible to depression, anxiety, and other negative effects of stress.

Wheat Gene Database is Tool for Improved Yield and Nutrition

By Ann Filmer

Plant scientists and wheat breeders now have a new tool to develop more nutritious and productive wheat varieties: A public online database of 10 million mutations in wheat genes. Scientists at UC Davis and three institutions in the UK created the database, which will allow scientists worldwide to study the function of every gene of wheat. The research will be reported in Proceedings of the National Academy of Sciences this week.

UC Davis Plant Sciences Professor, Jorge Dubcovsky is working to improve the yield and nutritional value of wheat, one of the world's most important crops.
