“…4). It suggests that sweet orange is able to activate its defense mechanism at the late stage of HLB infection, similar to the results reported by our previous work (Fan et al 2011) and the work of Kim and associates (2009) and Albrecht and Bowman (2011b). In addition, our results showed that inoculation of rough lemon and sweet orange with 'Ca.…”

Although there are no known sources of genetic resistance, some Citrus spp. are reportedly tolerant to huanglongbing (HLB), presumably caused by 'Candidatus Liberibacter asiaticus'. Time-course transcriptional analysis of tolerant rough lemon (Citrus jambhiri) and susceptible sweet orange (C. sinensis) in response to 'Ca. L. asiaticus' infection showed more genes differentially expressed in HLB-affected rough lemon than sweet orange at early stages but substantially fewer at late time points, possibly a critical factor underlying differences in sensitivity to 'Ca. L. asiaticus'. Pathway analysis revealed that stress responses were distinctively modulated in rough lemon and sweet orange. Although microscopic changes (e.g., callose deposition in sieve elements and phloem cell collapse) were found in both infected species, remarkably, phloem transport activity in midribs of source leaves in rough lemon was much less affected by HLB than in sweet orange. The difference in phloem cell transport activities is also implicated in the differential sensitivity to HLB between the two species. The results potentially lead to identification of key genes and the genetic mechanism in rough lemon to restrain disease development and maintain (or recover) phloem transport activity. These potential candidate genes may be used for improving citrus tolerance (or even resistance) to HLB by genetic engineering.

“…Similar observations were noticed in citrus-Huanglongbing (HLB) transcriptome, wherein only 17 genes were modulated in resistant genotype (US 897) in comparison to 326 genes that were significantly upregulated in the susceptible citrus genotype (Cleopatra) (Albrecht and Bowman, 2012). Of the 17 genes, the constitutive disease resistance 1 (CDR1) gene was highly expressed in resistant genotype (11.2 fold in uninfected US 897 as compared with 3.3 fold in uninfected Cleopatra).…”

“…This family of proteins is comprised of enzymes that are involved in various plant metabolic processes, including ethylene biosynthesis, flavonoid synthesis, and coumarin (defense-related) biosynthesis [44]. Genes of 2-oxoglutarate oxygenase are also reportedly induced on infection in citrus [45]. The present findings indicate that 2-oxoglutarate Fe (II)-dependent…”
