This project is a continuation of the funding that has been provided to SGC to provide an HLB detection laboratory that is available to growers and researchers throughout the state. For the third quarter (1/1/2016 – 3/31/2016), 8,618 samples were processed. Of those, 8,336 were plant samples and 282 were psyllid samples. To date for the funding period, a total of 24,018 samples have been run of which 22,796 were plant samples and 1222 were psyllid samples. SGC has developed a procedure to extract DNA from roots and has been running a limited number of samples for selected experiments. The procedure adds an additional step to the DNA extraction procedure (and about $1.50 more to the cost) but it still allows us to use robotic extraction and the Qiagen magnetic bead chemistry.
