Navel oranges are the most widely grown citrus type in California. Because they are seedless, navel oranges cannot be improved with conventional breeding. As a result, this variety is particularly vulnerable to the introduction of new pests and pathogens.
Citrus varieties that are unavailable from the CCPP exist in California and elsewhere that hobbyists would like to grow in California. With the presence of the Asian citrus psyllid and HLB in California, such varieties represent a severe threat to citrus in California because hobbyists may propagate them using diseased budwood.
We propose to develop a streamlined strategy for effective gene editing of Citrus in order to engineer disease resistance in already established horticulturally important cultivars. Building on our prior work, we will develop a suite of methods aimed at rapidly and efficiently editing genes involved in HLB susceptibility.
