Tools to learn about the battle against HLB
Questions? We have answers.
We have a PowerPoint presentation, prepared for grower and end-user audiences and tailored for specific venues, which provides general background on the genetics that are used to modify crops, and provide information on state and national regulatory approaches and consumer attitudes. Here are examples of the questions that are addressed:
- What are the general processes of genetically modifying plants and insects?
- When and where did huanglongbing (HLB) come from?
- What are some genetic approaches to controlling HLB?
- What is consumer response to engineered crops and foods?
Technologies developed to fight HLB
Every year California’s diverse ecosystem is invaded by new, often-destructive species of exotic pests, resulting in annual economic losses of more than $3 billion. The University of California at Davis has received $4.58 million, bolstering plant pathology researcher Bryce Falk’s work on preventing huanglongbing (HLB) using RNA technology.
The University of California Davis, UC Riverside, University of Florida, California Institute of Technology, USDA-ARS Fort Pierce FL, and the University of Arizona received $9 million to develop a ‘nupsyllid’ that is incapable of transmitting the bacterium. If successful, this program would release the nupsyllids who will then displace the wild psyllids and reduce spread of HLB. Approaches to altering the psyllid include infecting psyllids with Wohlbachia or viruses that reduce their ability to reproduce or their ability to transmit the Clas bacterium and also directly transforming the genes of the psyllid.
