Effects of Temperature on ‘Candidatus Liberibacter solanacearum’ and Zebra Chip Potato Disease Symptom Development

Citation
Munyaneza et al. (2012). Plant Disease 96 (1)
Names
“Liberibacter solanacearum”
Abstract
Temperature has been shown to have a significant effect on development of liberibacter species associated with citrus Huanglongbing disease. ‘Candidatus Liberibacter africanus’ and ‘Ca. L. americanus’ are both heat sensitive, whereas ‘Ca. L. asiaticus’ is heat tolerant. The recently described ‘Ca. L. solanacearum’ is associated with zebra chip (ZC), a newly emerging and economically important disease of potato worldwide. This psyllid-transmitted liberibacter species severely affects several oth

Effect of ‘Candidatus Liberibacter solanacearum’ on Fitness of Its Insect Vector, Bactericera cockerelli (Hemiptera: Triozidae), on Tomato

Names
“Liberibacter solanacearum”
Abstract
The potato/tomato psyllid, Bactericera cockerelli transmits the bacterium ‘Candidatus Liberibacter solanacearum’, also known as ‘Ca. L. psyllaurous’, which causes zebra chip disease in solanaceous crops. There have been no studies addressing the effect of the bacterial plant pathogen on the biology of its insect vector. We examined several life-history traits, including 7-day fecundity, hatching percentage, incubation time, nymphal survival percentage, nymphal development time, total developmen

First Report of ‘Candidatus Phytoplasma asteris’ Associated with Oilseed Rape Phyllody in Poland

Citation

Names
Ca. Phytoplasma asteris
Abstract
Winter oilseed rape (Brassica napus L.) is widely grown in Poland to produce vegetable oil for industrial processing of human and animal feed. In recent years, according to European Union directives on the use of biofuels (Directive 2003/30/EC), the area under oilseed rape cultivation in Poland has dramatically increased to 810,000 ha in 2009 and is still increasing. Morphological deformations of winter oilseed rape indicative of phytoplasma infection have been observed sporadically in Poland s
