First Report of ‘Candidatus Liberibacter solanacearum’ Naturally Infecting Tomatoes in the State of Mexico, Mexico

Citation
Ling et al. (2011). Plant Disease 95 (8)
Names
“Liberibacter solanacearum”
Abstract
In January 2011, tomato (Solanum lycopersicum) plants exhibiting stunting, yellow mosaic, short, chlorotic leaves, aborted flowers, and reduced-size fruits, symptoms similar to those exhibited by plants infected by ‘Candidatus Liberibacter solanacearum’ (2), were observed in approximately 5% of tomato plants in greenhouses in Jocotitlan in the State of Mexico, Mexico. Occasional plant recovery was also observed. Tomato plants in this facility were previously shown to be infected by Mexican papi

Lack of Evidence for Seed Transmission of ‘Candidatus Liberibacter africanus’ Associated with Greening (Huanglongbing) in Citrus in South Africa

Citation
van Vuuren et al. (2011). Plant Disease 95 (8)
Names
Ca. Liberibacter africanus
Abstract
‘Candidatus Liberibacter africanus’ is associated with citrus greening (huanglongbing [HLB]) in South Africa. Various unpublished reports have suggested that the related bacterium ‘Ca. L. asiaticus’ associated with HLB in citrus might be seed transmissible based on real-time PCR results. Seed transmission poses a risk of long distance disease spread, especially with the dissemination of rootstock seed. Therefore, it was essential to determine whether ‘Ca. L. africanus’ is seed transmitted in ci

Molecular Characterization of ‘Candidatus Phytoplasma asteris’ Associated with Aster Yellows-Diseased Potatoes in China

Citation
Cheng et al. (2011). Plant Disease 95 (6)
Names
Ca. Phytoplasma asteris
Abstract
Potatoes (Solanum tuberosum) are one of the most important crops in China following rice, wheat, and corn. Aster yellows phytoplasma appeared to be widespread in China; it was found to cause diseases on alfalfa, oranges, peaches, periwinkles, bamboo (1), and cactus (4). However, scant information of this pathogen on potatoes is available except for a few short reports published during the 1950s. During the potato disease surveys conducted from 2005 to 2010 in Yunnan and Inner Mongolia, 10 to 35
