In 2011, researchers developed a technique, called phage-assisted continuous evolution (or PACE), that rapidly generates proteins with new, sought-after properties and therapeutic potential. Originally conceived as a tool for pharmaceutical development, the researchers now have shown its potential in protecting crops from insects.

UF/IFAS Researchers Try to Cut Costs to Control Aquatic Invasive Plants in Florida

Aquaticinvasivesplants062816.jpg

From 2008 to 2015, state and federal water resource managers spent about $125 million to control invasive aquatic plants in Florida, according to an April Extension document co-written by Lyn Gettys, a UF/IFAS assistant professor of agronomy and aquatic weed specialist. Of all the invasive plants in Florida’s waterways, hydrilla costs the most to contain -- $66 million over a seven-year period.

A “Fitbit” for Plants?

P1010255.JPG

Knowing what physical traits a plant has is called phenotyping. Because it is such a labor intensive process, scientists are working to develop technology that makes phenotyping much easier. The tool is called the Phenocart, and it captures essential plant health data. The Phenocart measures plant vital signs like growth rate and color, the same way a Fitbit monitors human health signals like blood pressure and physical activity.

UF/IFAS Researchers to Study How to Reduce Carbon Dioxide in Ranch Soil

CattleResearchGrants1081815.jpg

“The goal is to put together a model that can predict the release of greenhouse gases like carbon dioxide and nitrous oxide from soils under a climate that is expected to be warmer and experience more extreme dry and wet periods across the Southeast,” said Stefan Gerber, a UF/IFAS assistant professor in soil and water sciences and one of the investigators on the new study.

Nematode Containment Facility Has Ability to Inspect Soil and Plants Prior to Export

NMSU has made upgrades to its nematode containment facility, which provides producers with the certification of sites being free of nematodes. The facility is now able to successfully accommodate and inspect a large amount of plant samples at one time. Funding was also used for new equipment to improve the molecular characterization of nematodes.
