42 In this review, we summarize the current knowledge on three pathogens that exhibit
43 distinct tissue specificity and modes of pathogenesis in citrus plants. XanthomonasXanthomonas
44 axonopodis pv. citri causes canker disease and invades the host leaf mesophyll tissue
45 through natural openings and can also survive as an epiphyte. X. fastidiosa and Ca.
46 Liberibacter are vectored by insects and proliferate in the vascular system of the host,
47 either in the phloem (Ca. Liberibacter) or xylem (X. fastidiosa) causing variegated
48 chlorosis and huanglongbing diseases, respectively. Ca. Liberibacter can be found
49 within host cells and is thus unique as an intracellular phytopathogenic bacterium.
50 Genome sequence comparisons have identified groups of species-specific genes that
51 may be associated with the particular lifestyle, mode of transmission or symptoms
52 produced by each phytopathogen. In addition, components that are conserved among
53 bacteria may have diverse regulatory actions underpinning the different bacterial
54 lifestyles; one example is the divergent role of the Rpf/DSF cell-cell signalling system
55 in X. citri and X.fastidiosa. Biofilm plays a key role in epiphytic fitness and canker
56 development in X. citri and in the symptoms produced by X. fastidiosa. Bacterial
57 aggregation may be associated with vascular occlusion of the xylem vessels and
