Ward's Research Featured on KU Today

Monday, February 11, 2013

Joy Ward’s research project funded by the National Science Foundation was recently featured in KU Today’s Headlines for February 11, 2013.  In response to climate change, many plant species seem to be flowering earlier than in the past—and scientists have assumed this was due to increasing global temperatures.  But Ward’s recent research titled, Identification of a major QTL that alters flowering time at elevated [CO2] in Arabidopsis thaliana, has shown that higher concentrations of carbon dioxide (CO2) in the atmosphere might play a direct role in influencing flowering times, and this may be as large or larger than the warming effect.  Ward in collaboration with her colleague, John Kelly, professor of ecology and evolutionary biology, have pinpointed the region of a plant’s genome that drives changes in flowering time in response to atmosphere levels of CO2, a breakthrough finding that shows the genetic architecture behind changes in flowering time in response to CO2 in Arabidopsis thaliana, a model species whose genome has been completely sequenced.
