Liberibacter asiaticus (\u003cjats:italic\u003eC\u003c/jats:italic\u003eLas) the most aggressive species. \u003cjats:italic\u003eC\u003c/jats:italic\u003eLas is vectored by the psyllid \u003cjats:italic\u003eDiaphorina citri\u003c/jats:italic\u003e and introduced into sieve cells, establishing a successful infection in all \u003cjats:italic\u003eCitrus\u003c/jats:italic\u003e species. Partial or complete resistance has been documented in the distant relatives \u003cjats:italic\u003eMurraya paniculata\u003c/jats:italic\u003e and \u003cjats:italic\u003eBergera koenigii\u003c/jats:italic\u003e, respectively, providing excellent systems to investigate the molecular basis of HLB-resistance. It has been shown previously that the first weeks after bacterial release into the phloem are critical for the establishment of the bacterium. In this study, a thorough transcriptomic analysis of young flushes exposed to \u003cjats:italic\u003eC\u003c/jats:italic\u003eLas-positive and negative psyllids has been performed in \u003cjats:italic\u003eCitrus × sinensis\u003c/jats:italic\u003e, as well as in the aforementioned resistant species, along the first eight weeks after exposure. Our results indicate that the resistant species do not deploy a classical immunity response upon \u003cjats:italic\u003eC\u003c/jats:italic\u003eLas recognition. Instead, transcriptome changes are scarce and only a few genes are differentially expressed when flushes exposed to \u003cjats:italic\u003eC\u003c/jats:italic\u003eLas-positive and negative psyllid are compared. Functional analysis suggests that primary metabolism and other basic cellular functions could be rewired in the resistant species to limit infection. Transcriptomes of young flushes of the three species are very different, supporting the existence of distinct biochemical niches for the bacterium. These findings suggest that both intrinsic metabolic inadequacies to \u003cjats:italic\u003eC\u003c/jats:italic\u003eLas survival, as well as inducible reprogramming of physiological functions upon \u003cjats:italic\u003eC\u003c/jats:italic\u003eLas recognition, could orchestrate together restriction of bacterial multiplication in these resistant hosts.\u003c/jats:p\u003e","long_citation_html":"Alves et al.
