  abstract = {{T}axonomy {B}acteria; {P}hylum {P}roteobacteria; {C}lass {G}ammaproteobacteria; {O}rder {L}ysobacterales (earlier synonym of {X}anthomonadales); {F}amily {L}ysobacteraceae (earlier synonym of {X}anthomonadaceae); {G}enus {X}anthomonas; {S}pecies {X}. hortorum; {P}athovars: pv. carotae, pv. vitians, pv. hederae, pv. pelargonii, pv. taraxaci, pv. cynarae, and pv. gardneri. {H}ost range {X}anthomonas hortorum affects agricultural crops, and horticultural and wild plants. {T}omato, carrot, artichoke, lettuce, pelargonium, ivy, and dandelion were originally described as the main natural hosts of the seven separate pathovars. {A}rtificial inoculation experiments also revealed other hosts. {T}he natural and experimental host ranges are expected to be broader than initially assumed. {A}dditionally, several strains, yet to be assigned to a pathovar within {X}. hortorum, cause diseases on several other plant species such as peony, sweet wormwood, lavender, and oak-leaf hydrangea. {E}pidemiology and control {X}. hortorum pathovars are mainly disseminated by infected seeds (e.g., {X}. hortorum pvs carotae and vitians) or cuttings (e.g., {X}. hortorum pv. pelargonii) and can be further dispersed by wind and rain, or mechanically transferred during planting and cultivation. {G}lobal trade of plants, seeds, and other propagating material constitutes a major pathway for their introduction and spread into new geographical areas. {T}he propagules of some pathovars (e.g., {X}. horturum pv. pelargonii) are spread by insect vectors, while those of others can survive in crop residues and soils, and overwinter until the following growing season (e.g., {X}. hortorum pvs vitians and carotae). {C}ontrol measures against {X}. hortorum pathovars are varied and include exclusion strategies (i.e., by using certification programmes and quarantine regulations) to multiple agricultural practices such as the application of phytosanitary products. {C}opper-based compounds against {X}. hortorum are used, but the emergence of copper-tolerant strains represents a major threat for their effective management. {W}ith the current lack of efficient chemical or biological disease management strategies, host resistance appears promising, but is not without challenges. {T}he intrastrain genetic variability within the same pathovar poses a challenge for breeding cultivars with durable resistance. {U}seful websites , , , ,},
