Citrus x paradisi Transcriptome or Gene expression

Huanglongbing (HLB) is currently the most destructive disease of citrus worldwide. Although there is no immune cultivar, field tolerance to HLB within citrus and citrus relatives has been observed at the USDA Picos farm at Ft. Pierce, Florida, where plants are exposed to a very high level of HLB pressure. It is apparent that some citrus types are more tolerant to HLB. By profiling the transcriptome of HLB tolerant and HLB susceptible citrus trees, we could find out the candidate genes that have been suppressed or activated in HLB tolerant citrus tree, which lead to the promotion of the basal resistance or immunity of citrus trees. This study may help us understand HLB-tolerance and provide guidance for breeding HLB-tolerant citrus in the future.
