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

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.

Microarray analysis of NAD-treated and water-treated Pineapple sweet orange

Project description:The goal of the microarray experiment was to identify genes that were differentially expressed in NAD-treated and water-treated sweet orange leaf tissues. Results indicated that, compared with the water treatment, the NAD tretament triggered profound transcriptome changes in the citrus leaves, with about 1,200 genes being up-regulated or down-regulated by twofold or more.

A genomic approach to bud mutation in sweet orange (Citrus sinensis L. Osbeck) fruit

Project description:Bud mutations arise often in citrus. The selection of mutants is one of the most important breeding methods in citrus. However, the molecular bases of bud mutation have rarely been studied. To identify the potential important or novel genes involved in bud mutation, different transcriptomic techniques combing suppression subtractive hybridization (SSH) and microarray were performed between a lycopene accumulated mutant, ‘Hong Anliu’ sweet orange (Citrus sinensis L. Osbeck), and its wild-type during fruit maturation. Microarray analysis revealed that differentially expressed clones are extensively coordinated with the initiation of lycopene accumulation. After sequencing of the differentially expressed clones, a total of 267 non-redundant transcripts were obtained, 182 (68.2%) of which share homology (E-value ≤ 1×10-10) with known gene products or known protein domains. A list of candidate genes which involved in cellular metabolic process, primary metabolic process, localization, macromolecular metabolic process was obtained. Out of these genes, 12 share homology with previously described signal transduction or transcription factors, suggesting complex regulatory control. These results demonstrate profound effect on gene expression of bud mutation in citrus fruits and provide new insights into the molecular basis of bud mutation. Keywords: bud mutation, candidate genes, Citrus, cNDA microarray, suppression subtractive hybridization (SSH)

Keywords: bud mutation, candidate genes, Citrus, cNDA microarray, suppression subtractive hybridization (SSH) Fruits from the mutant and its wild type were collected at five time points from August to December. Total RNA extracted from the mutant was hybridized to the array together with RNA from the wild type. Each hybridization was performed in duplicate by dye swap.

Transcriptome dynamics during fruit development of sweet orange (Citrus sinensis)

Project description:• To dissect how the genes are dynamically and differentially expressed during fruit development in sweet orange, a comprehensive transcriptomic study was performed in a pleiotropic mutant (MT) and its wild type (WT). • The detection of the fruit transcriptomic changes was conducted at five stages of fruit development by deep sequencing; the obtained millions of reliable tags were mapped on orange unigenes and subjected to cluster analysis and functional categorization. Sugar and organic acid contents were determined based on the prediction of differential biological processes. • The global clustering analysis revealed a total of 14 expression patterns for the genes involved in fruit development of sweet orange. More than 94% of the genes showed differential expression during fruit development. Comparative transcripts profiling between WT and MT revealed that between 410 and 634 genes were significantly differentially expressed at the five stages. Functional categorization indicated that TCA cycle, carotenoid biosynthesis, and pentose phosphate pathway (OPP) were among the most regulated pathways. • This study provided a dynamic-view of the transcriptome changes during fruit ripening in sweet orange; the results highlighted a set of molecular processes involved in the formation of the mutation trait in the orange fruits. Investigate the transcriptome changes during five fruit developmental stages of two sweet orange genotypes
