NC State scientists are exploring the molecular-level processes that cause tomatoes to ripen, and what they find could have big implications for a range of traits -- from flavor to firmness -- in fruit-bearing crops.
CALS Student Scientists Dance – With Research
CALS students push themselves beyond traditional science classes, and in turn, find fresh perspective and a much-needed outlet for stress relief and creative thinking.
Student Spotlight: Estefania Castro-Vazquez Uses Science To Serve
Estefania Castro-Vazquez is still exploring possible career goals, but her motivation is already clear: putting science to work to improve lives.
I AM CALS
Brooklynn Newberry wanted to be the first in her limited-income family to get a degree. When her first CALS application was deferred, she chose an alternate path.
Modeling tool IDs genes that control plants’ stress response
An interdisciplinary team of researchers from North Carolina State University and University of California, Davis has developed a modeling algorithm that is able to identify plant genes associated with specific biological functions. The modeling tool will help plant biologists target individual genes that control how plants respond to environmental stressors.
One size doesn’t fit all
A general cross-continent model to predict the effects of climate change on savanna vegetation isn’t as effective as examining individual savannas by continent, according to research published in Science this week. Savannas – grasslands dotted with trees – cover about 20 percent of the earth’s land and play a critical role in storing atmospheric carbon, says Dr. William Hoffmann, associate professor of plant and microbial biology at North Carolina State University and co-author of the study. “We wanted to find out what controls savanna vegetation – essentially the density of trees within the savanna – and whether we can use a single global model to predict what will happen to savannas if global temperatures rise,” Hoffmann said.
Interns learn valuable life lessons while studying tropical plant pathology in Costa Rica
Mary Lewis spent six weeks traveling around Costa Rica working on research designed to shed light on one of the most important diseases affecting bananas. While her focus was the fungal disease black sigatoka, the College of Agriculture and Life Sciences student says the experience taught her just as much – or more – about what it takes to work in a foreign country and to interact with people from other cultures.
Solving molecular mysteries
Over the years he’s spent studying cassava mosaic disease, Tanzanian scientist Dr. Joseph Ndunguru has noted something curious: Wherever there are DNA molecules called satellites associated with the geminiviruses contributing to the disease, symptoms are greater and losses are heavier – even in plants bred specifically to resist the disease. Figuring out more about those subviral particles could be key, Ndunguru believes, to developing a strategy to beat the disease for good. That’s why he has teamed with CALS’ Dr. Linda Hanley-Bowdoin on a project designed to yield the scientific insight necessary to do just that.
Designing jet fuels of the future
Using micro-organisms able to survive in some of the most extreme environments on Earth, two CALS researchers are working to turn plants and algae into oil-producing factories efficient enough to help solve the problem of the world’s diminishing petroleum reserves.
David Higgins: Figuring out flower development
This CALS senior and recipient of a national undergraduate research fellowship isn't content to leave scientific questions unanswered. With plant geneticist Dr. Bob Franks, he's been studying how flowers develop.
