“…CaLso is transmitted from potato mother tubers to growing plants and to progeny tubers (Pitman et al, 2011) and is a carrot seed borne pathogen , which poses a high risk of introduction of the bacterium into new areas in which contaminated carrot seeds are commercialized. The bacterium is also horizontally and naturally spread by different psyllid species (Hemiptera: Psylloidea) following establishment (Hansen et al, 2008;Alfaro-Fernández et al, 2012;Nissinen et al, 2014).…”

The bacterium 'Candidatus Liberibacter solanacearum' is a recent plant pathogen of several crops in Solanaceae and Apiaceae and is associated with economically important diseases. The bacterium is a carrot seed borne pathogen that can also be transmitted from potato mother tubers and by psyllid vectors. The psyllid Bactericera trigonica Hodkinson was described carrying CaLso associated with vegetative disorders in carrot and celery crops in Spain and its competence to transmit this phloem-limited bacterium among vegetables is currently being investigated. Here electrical penetration graphs showed that B. trigonica fed in the phloem of carrot and celery and probed the phloem in potato, but not in tomato plants. The bacterium was efficiently transmitted to carrot and celery plants when either single B. trigonica or groups of ten fed on these species. An inoculation access period of 24 hours was sufficient for a single B. trigonica to transmit the bacterium to carrot (67.8%), celery (21.1%) and eventually to potato and tomato (6.0%). Higher transmission rates were obtained with 10 individuals on celery (100%), carrot (80%), potato (10%) and tomato (10%). Bactericera trigonica laid eggs, and the hatched nymphs develop into adult on carrot and celery, but not on potato and tomato. CaLso was detected in 20% of the eggs laid by females carrying the bacterium. The results confirmed that B. trigonica is a vector of the bacterium to carrot and celery, and it is discussed the potential role of this psyllid in the transmission of the pathogen to potato and tomato plants.Additional keywords: electrical penetration graph; haplotype E; psyllids; real-time PCR; transovarial passage.

“…Liberibacter psyllaurous' (Hansen et al, 2008), is a gramnegative, phloem-limited, and psyllid-vectored bacterium in the family Rhizobiaceae of the α-Proteobacteria group. The bacterium is associated with zebra chip, which is one of the most economically important bacterial diseases of potato (Solanum tuberosum L.).…”

“…All previously described species of the genus 'Ca. Liberibacter' are transmitted through an insect vector of the family Psyllidae (Capoor et al, 1967;Hansen et al, 2008;Raddadi et al, 2011). Whether BT-1 T inhabits an insect host is unknown; however, the leafhopper Empoasca papayae is recommended for further study due to previous documentation of its association with phloem-limited bacteria in papaya (Pérez et al, 2010).…”

The Gram-stain-negative, rod-shaped bacterial isolate BT-1T is the closest relative to the genus ‘Candidatus Liberibacter ’ cultured to date. BT-1T was recovered from the phloem sap of a defoliating mountain papaya in Puerto Rico. The BT-1T 16S rRNA gene sequence showed that strain BT-1T is most closely related to members of the genus ‘Ca. Liberibacter ’ sharing 94.7 % 16S rRNA gene sequence similarity with ‘Ca. Liberibacter americanus ’ and ‘Ca. Liberibacter asiaticus ’. Additionally, average nucleotide identity, 16S rRNA gene sequences and conserved protein sequences supported inclusion of the previously described species of the genus ‘Ca. Liberibacter ’ in a genus with BT-1T. The prominent fatty acids of isolate BT-1T were C18 : 1ω7c (77.2 %), C16 : 0 OH (4.8 %), C18 : 0 (4.4 %) and C16 : 0 (3.5 %). Both physiological and genomic characteristics support the creation of the genus Liberibacter , as well as the novel species Liberibacter crescens gen. nov., sp. nov. with type strain BT-1T ( = ATCC BAA-2481T = DSM 26877T).
