Names
Ca. Phytoplasma pruni Ca. Phytoplasma
Abstract
Western X (WX) disease, caused by ‘Candidatus Phytoplasma pruni’, is a devastating disease of sweet cherry resulting in the production of small, bitter-flavored fruits that are unmarketable. Escalation of WX disease in Washington State prompted the development of a rapid detection assay based on recombinase polymerase amplification (RPA) to facilitate timely removal and replacement of diseased trees. Here, we report on a reliable RPA assay targeting putative immunodominant protein coding region

Targeted Early Detection of Citrus Huanglongbing Causal Agent ‘Candidatus Liberibacter asiaticus’ Before Symptom Expression

Citation
Pandey, Wang (2019). Phytopathology® 109 (6)
Names
Ca. Liberibacter asiaticus
Abstract
Citrus Huanglongbing (HLB) is the most severe disease of citrus plants caused by ‘Candidatus Liberibacter asiaticus’ and transmitted by the insect vector Asian citrus psyllid (ACP). No effective curative measure is available against HLB. For citrus production areas without HLB or with low HLB disease incidence, removal of ‘Ca. L. asiaticus’ inoculum is critical to prevent HLB spread. Such a strategy requires robust early diagnosis of HLB for inoculum removal to prevent ACP acquisition and trans

A LAMP Protocol for the Detection of ‘Candidatus Phytoplasma pyri’, the Causal Agent of Pear Decline

Names
Ca. Phytoplasma pyri
Abstract
Phytoplasmas are cell-wall-less bacteria that cause diseases in approximately 1,000 plant species. ‘Candidatus Phytoplasma pyri’, the causal agent of pear decline, induces various symptoms on its hosts, leading to weakening and dieback of the plants, reduced fruit size and yield, and, consequently, considerable financial losses in all pear-growing areas. Fighting this disease requires a reliable and inexpensive method for pathogen detection in propagation material as well as plant stocks in orc

Taxonomic resolution of the genus Cyanothece (Chroococcales, Cyanobacteria), with a treatment on Gloeothece and three new genera, Crocosphaera, Rippkaea, and Zehria

Names
Crocosphaera watsonii T
Abstract
The systematics of single‐celled cyanobacteria represents a major challenge due to morphological convergence and application of various taxonomic concepts. The genus Cyanothece is one of the most problematic cases, as the name has been applied to oval‐shaped coccoid cyanobacteria lacking sheaths with little regard to their phylogenetic position and details of morphology and ultrastructure. Hereby we analyze an extensive set of complementary genetic and phenotypic evidence to disentangle the rela

Genetic Diversity of ‘Candidatus Liberibacter asiaticus’ Revealed by Short Tandem Repeats and Prophage Typing Indicates Population Homogeneity in Brazil

Names
Ca. Liberibacter asiaticus
Abstract
‘Candidatus Liberibacter asiaticus’ is the most common huanglongbing-associated bacteria, being present in Asia, South, Central, and North America. Genomic approaches enabled sequencing of ‘Ca. L. asiaticus’ genomes, allowing for a broader assessment of its genetic variability with the application of polymerase chain reaction (PCR)-based tools such as microsatellite or short tandem repeat (STR) analysis. Although these tools contributed to a detailed analysis of strains from Japan, China, and t
