Project description:The green rice leafhopper Nephotettix cincticeps have two mutualistic symbiotic bacteria (Candidatus Sulcia muelleri and Candidatus Nasuia deltocephalinicola) in its symbiont special organ bacteriome and are also infected to rickettsia. In order to determine immune challenge is induced or not in N. cincticeps, we investigated gene expression of Escherichia coli challenged N. cincticeps.
Project description:The green rice leafhopper Nephotettix cincticeps have two mutualistic symbiotic bacteria (Candidatus Sulcia muelleri and Candidatus Nasuia deltocephalinicola) in its symbiont special organ bacteriome and are also infected to rickettsia. In order to determine immune challenge is induced or not by rickettsia infection in N. cincticeps, we investigated gene expression between rickettsia-infected and rifampicin treated uninfected N. cincticeps colonies.
Project description:Two bacterial symbionts of the European pest leafhopper, Macrosteles quadripunctulatus (Hemiptera: Cicadellidae), were fully sequenced. "Candidatus Sulcia muelleri" and "Ca. Nasuia deltocephalinicola" represent two of the smallest known bacterial genomes at 190 kb and 112 kb, respectively. Genome sequences are nearly identical to strains reported from the closely related host species, M. quadrilineatus.
Project description:The global transcriptional responses of the adult potato psyllid gut upon infection of the two Candidatus Liberibacter solanacearum (Lso) haplotypes using Illumina sequencing
Project description:HLB is suggested to be caused by the phloem-limited fastidious prokaryotic α-proteobacterium “Candidatus Liberibacter spp.” Previous studies focused on the proteome and transcriptome analyses of citrus 5 to 35-week-after “Ca. L. spp.” inoculation. In this study, gene expression profiles was analyzed using mandarin of Citrus reticulate Blanco cv. jiaogan leaves after 2-year infection with “Ca. L. asiaticus”. The Affymetrix GeneChip® citrus genome were applied to study the molecular pathways mediated by “Ca. L. asiaticus” inoculated 3-year-old jiaogan seedlings. Each of them was graft-inoculated with one sweet orange scions with or without “Ca. L. asiaticus” in Dectember, 2009. RNA samples from three mandarin trees infected with 'Candidatus Liberibacter asiaticus' and three uninfected trees were used for affymatrix genochip
