Infection by Candidatus Liberibacter solanacearum’ haplotypes A and B in Solanum lycopersicum ‘Moneymaker’

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

Dynamics of ‘Candidatus Liberibacter asiaticus’ Colonization of New Growth of Citrus

Citation

Names
Ca. Liberibacter asiaticus
Abstract
‘Candidatus Liberibacter asiaticus’ is a phloem-colonizing intracellular bacterial pathogen of citrus associated with the disease huanglongbing. A study of patterns of colonization and bacterial population growth in new growth of different citrus types was conducted by pruning infected citron, sweet orange, sour orange, mandarin, citrange, and Citrus macrophylla trees to force the growth of axillary and adventitious shoots. The first three leaves on newly emerged shoots were collected at 30, 60

‘CandidatusLiberibacter solanacearum’ Is Tightly Associated with Carrot Yellows Symptoms in Israel and Transmitted by the Prevalent Psyllid VectorBactericera trigonica

Names
“Liberibacter solanacearum”
Abstract
Carrot yellows disease has been associated for many years with the Gram-positive, insect-vectored bacteria, ‘Candidatus Phytoplasma’ and Spiroplasma citri. However, reports in the last decade also link carrot yellows symptoms with a different, Gram-negative, insect-vectored bacterium, ‘Ca. Liberibacter solanacearum’. Our study shows that to date ‘Ca. L. solanacearum’ is tightly associated with carrot yellows symptoms across Israel. The genetic variant found in Israel is most similar to haplotype

The Asian Citrus Psyllid Host Murraya koenigii Is Immune to Citrus Huanglongbing Pathogen ‘Candidatus Liberibacter asiaticus’

Citation
Beloti et al. (2018). Phytopathology® 108 (9)
Names
Ca. Liberibacter asiaticus
Abstract
The Asian citrus psyllid (ACP) Diaphorina citri, vector of ‘Candidatus Liberibacter asiaticus’ (CLas), the putative causal agent of citrus Huanglongbing (HLB), is controlled by application of insecticides, which, although effective, has resulted in serious biological imbalances. New management tools are needed, and the technique known as “trap crop” has been attracting attention. A potential plant for use as a trap crop in the management of the ACP is Murraya koenigii (curry leaf). However, for

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

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
