Gene expression profiles of Washington navel oranges (Citrus sinensis (L) Osbeck) graft innoculated with Candidatus Liberibacter asiaticus, Spiroplasma citri, or two citrus tristeza isolates

Project description:Pathogens can trigger a broad array of changes in gene expression in plants. In this study we report the changes in gene expression patterns that occurred when greenhouse grown Washington Navel oranges (C. sinensis) was graft innoculated with citrus pathogens. Candidatus Liberibacter asiaticus, Spiroplasma citri, and two isolates of citrus tristeza virus were studied.

Enriched vascular proteomics reveals insights to the role of peroxidase and serine proteases during infection with Candidatus Liberibacter asiaticus (CLas) in Washington navel.

Project description:The dataset for this project was to identify significantly changing proteins in the vasculature of Washington Navel (Citrus sinensis (L) Osbeck) during Candidatus Liberibacter asiaticus (CLas) infection. The navel trees were graft-inoculated with the Hacienda Heights, CA CLas strain (HHCA) and then sampled ten months after graft inoculation.

Response of Sweet Orange (Citrus sinensis) to Candidatus Liberibacter asiaticus Infection

Project description:Citrus greening or huanglongbing (HLB) is a devastating disease of citrus. HLB is associated with the phloem-limited fastidious prokaryotic alpha-proteobacterium Candidatus Liberibacter spp. In this report, we used sweet orange (Citrus sinensis) leaf tissue infected with 'Ca. Liberibacter asiaticus' and compared this with healthy controls. Investigation of the host response was examined with citrus microarray hybridization based on 30,171 sets expressed sequence tag sequences from several citrus species and hybrids. The microarray analysis indicated that HLB infection significantly affected expression of 624 genes whose encoded proteins were categorized according to function. The categories included genes associated with sugar metabolism, plant defense, phytohormone, and cell wall metabolism, as well as 14 other gene categories. Young, healthy Valencia sweet orange (C. sinensis) plants were graft inoculated with budwood from Ca. L. asiaticus-infected citrus plants. Prior to the innocualtion, the plants were confirmed to be Ca. L. asiaticus-free in ordinary and quantitative PCR tests. The presence of the bacteria in the inoculated plants was confirmed in both conventional and quantitative PCR with specific primers to Ca. L. asiaticus. The stem and root samples used for RNA extraction and hybridization on Affymetrix microarrays were obtained from three symptomatic and three healthy control trees of similar size, approximately 1 year after inoculation.

Transcriptional response of susceptible and tolerant citrus to infection with Candidatus Liberibacter asiaticus

Project description:Candidatus Liberibacter asiaticus (Las), a non-culturable phloem-limited bacterium, is the suspected causal agent of Huanglongbing (HLB) in Florida. HLB is one of the most devastating diseases of citrus and no resistant cultivars have been identified to date, though tolerance has been suggested in the genus Poncirus. A recent study conducted in our laboratory demonstrated tolerance of US-897, a hybrid of Poncirus trifoliata (L. Raf.) and the susceptible ‘Cleopatra’ mandarin (Citrus reticulata Blanco), to Ca. L. asiaticus, the presumed causal agent of HLB in Florida (Albrecht & Bowman, HortScience 46 (2011) 16-22). This study compares transcriptional changes in tolerant US-897 and susceptible ‘Cleopatra’ mandarin seedlings in response to infection with Las using the Affymetrix GeneChip citrus array with the main objective of identifying genes associated with tolerance to HLB. Such genes may be suitable as potential targets for biotechnology approaches, providing one strategy to possibly control this destructive disease of citrus.

Expression data from Senescence Process of citrus

Project description:The postharvest senescence processes of citrus fruits were analyzed transcriptomic. The present study was aimed to: further uncover the rind-flesh communication of hesperidium; characterize the differential storage behaviors of different citrus varieties; reveal the important changes during storing process; and demonstrate the specific non-climacteric characteristics of citrus fruits. We chose four major table fruit varieties of citrus: satsuma mandarin (Citrus unshiu Marc) (M), ponkan (Citrus reticulata Blanco) (K), newhall navel orange (Citrus sinensis L. Osbeck) (O) and shatian pummelo (Citrus grandis Osbeck) (P). They were sampled every 10 days during 50 DAH (days after harvest), almost covering the commercial storage period of loose-skin citrus.

Transcriptome profiling of Candidatus Liberibacter asiaticus in citrus and psyllids

Project description:Candidatus Liberibacter asiaticus (Las) is an emergent bacterial pathogen associated with the devastating citrus Huanglongbing (HLB), also known as the greening disease. Vectored by the Asian Citrus Psyllid (Diaphorina citri), Las colonizes the phloem tissue of citrus. So far, efforts of cultivating Las in vitro have not been successful and dual-transcriptome analyses could only detect ~100 Las genes due to the low abundance of bacterial RNA in infected citrus/psyllid tissues. Therefore, the biology of this pathogen is poorly understood. Here, we established a procedure to enrich Las RNA for transcriptome analysis in order to obtain insights into the interactions of Las with its two hosts. We were able to confidently determine the expression profiles of >400 Las genes, including 106 that were differentially expressed between citrus and psyllids. Genes related to transcription/translation and defense were found to be upregulated in citrus; whereas genes upregulated in psyllids are involved in metabolic pathways related to tricarboxylic acid (TCA) cycle. Genes encoding the succinate dehydrogenase and NADH quinone oxidoreductase complexes, as well as the flagellar system are also expressed to higher levels in psyllids. We also analyzed the relative expression levels of Sec-delivered effectors, which are considered key virulence factors of Las. This work advances our understanding of the HLB biology and offers novel insight into the HLB pathogenesis.

Transcriptional analyses of mandarins seriously infected by “Candidatus Liberibacter asiaticus”

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
