Pest categorisation of Palm lethal yellowing phytoplasmas [PDF]

, 2017
The EFSA Panelon Plant Health performed a pest categorisation of Palm lethal yellowing phytoplasmas for the EU territory. This name is used to describe diseases that share the same succession of symptoms in palms that are caused by a number of strains of

Evolutionary Diversification in Insect Vector–Phytoplasma–Plant Associations [PDF]

Annals of the Entomological Society of America, 2020
AbstractThe association between insect herbivores and vascular plants represents one of the greatest success stories in terrestrial evolution. Specific mechanisms generating diversity in the association remain poorly understood, but it has become increasingly clear that microbes play important roles in mediating plant–insect interactions.

Detection of Russian olive witches’-broom disease and its insect vector in Northwestern Iran

Journal of Plant Protection Research, 2017
Recently, Russian olive trees showing witches’-broom and little leaf symptoms have been widely observed in northwestern and central Iran. Polymerase chain reaction (PCR) and nested PCR assays using phytoplasma universal primer pairs confirmed phytoplasma

Detection of ‘Candidatus Phythoplasma prunorum’ in Apricot Trees and its Associated Psyllid Samples

Agronomy, 2023
‘Candidatus Phytoplasma prunorum’ is causing ever increasing economic losses through the decline of apricot trees in European countries, e.g., Hungary. In this study, the pathogen was identified from plant tissues and insects by nested-PCR.

Genome-wide analyses of Liberibacter species provides insights into evolution, phylogenetic relationships, and virulence factors. [PDF]

, 2020
'Candidatus Liberibacter' species are insect-transmitted, phloem-limited α-Proteobacteria in the order of Rhizobiales. The citrus industry is facing significant challenges due to huanglongbing, associated with infection from 'Candidatus Liberibacter ...

The grapevine microbiota: A review on the possible impacts of plant protection programs on phyllosphere microorganisms

Annals of Applied Biology, EarlyView.
This review highlights recent advances in understanding how plant protection programs and alternative fungicides affect the taxonomic composition of the grapevine phyllosphere microbiota. Bacterial and fungal communities are primarily shaped by the plant compartment, vineyard location, and sampling time. Plant protection programs generally have a minor

Identification d'insectes vecteurs "potentiels" du Cape Saint Paul Wilt sur le cocotier au Ghana par PCR [PDF]

, 2008
Le vecteur du phytoplasme responsable du jaunissement mortel du cocotier au Ghana est inconnu à ce jour. Il est cependant admis que les phytoplasmes sont transmis par des insectes piqueurs-suceurs, ces insectes étant supposés être les seuls à avoir la ...

Spatiotemporal dynamics and quantitative analysis of phytoplasmas in insect vectors [PDF]

Scientific Reports, 2020
AbstractPhytoplasmas are transmitted by insect vectors in a persistent propagative manner; however, detailed movements and multiplication patterns of phytoplasmas within vectors remain elusive. In this study, spatiotemporal dynamics of onion yellows (OY) phytoplasma in its vectorMacrosteles striifronswere investigated by immunohistochemistry-based 3D ...

Lethal Effects of the Wild Potato Solanum bulbocastanum on the Planthopper Pentastiridius leporinus, a Vector of Bacterial Pathogens in Potato

Journal of Applied Entomology, EarlyView.
ABSTRACT The planthopper Pentastiridius leporinus [Hemiptera: Cixiidae] is a vector of the two plant pathogenic bacteria ‘Candidatus Arsenophonus phytopathogenicus’ and ‘Candidatus Phytoplasma solani’ causing ‘bacterial potato tuber wilt’ in potato.
