Grosser said Gmitter continued …
Editing a plant’s genes is only half the battle. Before a new, improved trait can ever reach a farmer’s field, scientists must be able to grow a whole plant from just a few edited cells. That process can be slow, unreliable and, for some plant species, impossible. A new study describes a way to speed up that bottleneck across crops, …
By Christopher Vincent and Rashmi Kumari Florida summers come with intense sunlight, high temperatures and frequent rain. Just as people use sunscreen to protect exposed skin from intense sunlight, plants can benefit from a protective coating on exposed leaf and fruit surfaces. One way to provide this protection is by spraying a kaolin clay particle film on the tree. Although …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted a field day in Jason Griffin’s Polk County grove in mid-September.

By Lauren Fessler Mathews, Ana Redondo and Ozgur Batuman The positive impact of oxytetracycline (OTC) trunk injections for citrus production in HLB-infected trees has been well established. Additionally, there has been extensive work showing that plant defense inducers (PDIs) can help boost tree health and reduce symptom development from a variety of pathogens. Based on this, University of Florida Institute …
There’s been a great deal of effort over the past 15 years or so to develop or identify citrus varieties and rootstocks that have greater tolerance to HLB.
