Names
“Liberibacter solanacearum”
Abstract
‘Candidatus Liberibacter solanacearum’ is a plant pathogen associated with diseases affecting several crops of the Solanaceae and Apiaceae families. Two ‘Ca. L. solanacearum’ haplotypes (LsoA and LsoB) infect solanaceous crops in North America and are transmitted by the tomato psyllid Bactericera cockerelli. Although both ‘Ca. L. solanacearum’ haplotypes cause zebra chip in potato, the diseases associated with each haplotype in tomato (Solanum lycopersicum) have not been described. ‘Ca. L. sola

Genotyping Points to Divergent Evolution of ‘Candidatus Phytoplasma asteris’ Strains Causing North American Grapevine Yellows and Strains Causing Aster Yellows

Citation
Davis et al. (2018). Plant Disease 102 (9)
Names
Ca. Phytoplasma asteris
Abstract
Grapevine yellows diseases occur in cultivated grapevine (Vitis vinifera L.) on several continents, where the diseases are known by different names depending upon the identities of the causal phytoplasmas. In this study, phytoplasma strains associated with grapevine yellows disease (North American grapevine yellows [NAGY]) in vineyards of Pennsylvania were characterized as belonging to 16S ribosomal RNA (rRNA) gene restriction fragment length polymorphism group 16SrI (aster yellows phytoplasma

Postharvest Development of ‘Candidatus Liberibacter solanacearum’ in Late-Season Infected Potato Tubers under Commercial Storage Conditions

Citation
Rashed et al. (2018). Plant Disease 102 (3)
Names
“Liberibacter solanacearum”
Abstract
Zebra chip (ZC) disease of potato is associated with the putative pathogen ‘Candidatus Liberibacter solanacearum’, which is transmitted by the potato psyllid Bactericera cockerelli (Hem., Triozidae). The present study was initiated to investigate ‘Ca. L. solanacearum’ development during and following typical commercial storage practices. Using bacteriliferous psyllids, Russet Norkotah potato tubers were infested in field cages 14, 10, and 4 days before harvest. Changes in ‘Ca. L. solanacearum’
