‘Candidatus Liberibacter solanacearum’ distribution and diversity in Scotland and the characterisation of novel haplotypes from Craspedolepta spp. (Psylloidea: Aphalaridae)

Abstract: The phloem limited bacterium ‘Candidatus Liberibacter solanacearum’ (Lso) is associated with disease in Solanaceous and Apiaceous crops. This bacterium has previously been found in the UK in Trioza anthrisci, but its impact on UK crops is unknown. Psyllid and Lso diversity and distribution among fields across the major carrot growing areas of Scotland were assessed using real-time PCR and DNA barcoding techniques. Four Lso haplotypes were found: C, U, and two novel haplotypes. Lso haplotype C was also found in… Show more

“…The species Ca. L. psyllaurous is known to establish facultative infections in psyllids within the Bactericera and Trioza genera and has recently been detected in two Craspedolepta species (family Aphalaridae) collected in the United Kingdom (Sumner-Kalkun et al, 2020). Ca.…”

“…Phylogenetic comparison of the nucleic acid sequences from each of these genes identified these new sequences as most closely related to the newly described Ca. L. solanacearum haplotype H, identified in Finland from plant species in the Polygonaceae, and haplotypes Cras1a/1b and Cras2, discovered in Scotland infecting Craspedolepta (Aphalaridae) psyllids 19,20 . 'Ca.…”

“…Two haplotypes designated as H were described, one in carrots and in two species of Poligonaceae: Persicaria lapathifolia L. and Fallopia convolvulus L. in Finland [12], and another in Convolvulaceae species in USA [28]. Finally, haplotypes Cra1 and Cra2 have been found in psyllids from the Aphalaridae family: Craspedolepta nebulosa (Zetterstedt, 1828) and C. subpunctata (Foerster, 1848) in United Kingdom [29].…”
