Enhancing PCR Capacity To Detect ‘Candidatus Liberibacter asiaticus’ Utilizing Whole Genome Sequence Information

Names
Ca. Liberibacter asiaticus
Abstract
‘Candidatus Liberibacter asiaticus’ (CLas) is an unculturable α-proteobacterium associated with citrus Huanglongbing (HLB; yellow shoot disease). PCR procedures that accurately confirm or exclude CLas infection in citrus tissue/Asian citrus psyllid (ACP) samples are critical for HLB management. When CLas was described in 1994, a 23-bp signature oligonucleotide sequence (OI1) in the 16S rRNA gene (rrs, three genomic copies) was identified based on Sanger sequencing. OI1 contains single nucleotid

Interactions Between Solanaceous Crops and ‘Candidatus Liberibacter solanacearum’ Haplotypes in Relation to Infection and Psyllid Survival on the Hosts

Abstract
‘Candidatus Liberibacter solanacearum’ (Lso), transmitted by the potato psyllid (Bactericera cockerelli), is the putative causal agent of potato zebra chip disease. The bacterial pathogen infects a wide range of solanaceous plants (both wild and cultivated species), among which are peppers, potatoes, and tomatoes. Currently there are two commonly detected, genetically distinct haplotypes of Lso (A and B) identified from potatoes in the United States. To determine whether there are interactions
