‘Candidatus Phytoplasma asteris’ subgroups display distinct disease progression dynamics during the carrot growing season

Citation

Names
Ca. Phytoplasma asteris
Abstract
Aster Yellows phytoplasma (AYp; ‘Candidatus Phytoplasma asteris’) is an obligate bacterial pathogen that is the causative agent of multiple diseases in herbaceous plants. While this phytoplasma has been examined in depth for its disease characteristics, knowledge about the spatial and temporal dynamics of pathogen spread is lacking. The phytoplasma is found in plant’s phloem and is vectored by leafhoppers (Cicadellidae: Hemiptera), including the aster leafhopper, Macrosteles quadrilineatus Forbe

Genome-based reclassification of Amycolatopsis eurytherma as a later heterotypic synonym of Amycolatopsis thermoflava

Names
Amycolatopsis eurytherma Amycolatopsis thermoflava
Abstract
The present study was carried out to clarify the taxonomic assignment of two closely related Amycolatopsis species. Genomic information for 48 type strains was available at the time of conducting this analysis. Our analysis showed that two species, viz. Amycolatopsis eurytherma Kim et al. 2002 and

‘Candidatus Phytoplasma stylosanthis’, a novel taxon with a diverse host range in Australia, characterised using multilocus sequence analysis of 16S rRNA, secA, tuf, and rp genes

Names
Ca. Phytoplasma Ca. Phytoplasma luffae Ca. Phytoplasma stylosanthis
Abstract
In Australia, Stylosanthes little leaf (StLL) phytoplasma has been detected in Stylosanthes scabra Vogel, Arachis pintoi Krapov, Saccharum officinarum L., Carica papaya L., Medicago sativa L., and Solanum tuberosum L. The 16S rRNA gene sequence of StLL phytoplasma strains from S. scabra, C. papaya, S. officinarum and S. tuberosum were compared and share 99.93–100 % nucleotide sequence identity. Phylogenetic comparisons between the 16S rRNA genes of StLL phytoplasma and other ‘Candidatus Phytopla

The agent associated with blue dwarf disease in wheat represents a new phytoplasma taxon, ‘Candidatus Phytoplasma tritici’

Abstract
Wheat blue dwarf (WBD) is one of the most economically damaging cereal crop diseases in northwestern PR China. The agent associated with the WBD disease is a phytoplasma affiliated with the aster yellows (AY) group, subgroup C (16SrI-C). Since phytoplasma strains within the AY group are ecologically and genetically diverse, it has been conceived that the AY phytoplasma group may consist of more than one species. This communication presents evidence to demonstrate that, while each of the two 16 r
