Project description:To identify genes associated with citrus peel development and manifestation of peel disorders, we analyzed flavedo, albedo and juice sac tissues from five types of citrus fruit including, mandarin orange, navel orange, valencia orange, grapefruit and lemon. Fruits of five different citrus cultivars. Mature, healthy fruits of five different citrus cultivars (M-bM-^@M-^\ValenciaM-bM-^@M-^] and M-bM-^@M-^\NavelM-bM-^@M-^] orange [Citrus sinensis], mandarin [Citrus reticulata], lemon [Citrus M-CM-^W limon], grapefruit [Citrus M-CM-^W paradisi]) were purchased from a food market located in Davis, CA, USA. For all five types of fruit, three tissues (flavedo, albedo, and juice sacs) were compared separately. Each of the three tissues from each of the five types of fruit were sampled in three biological replicates, for a total of 45 samples. Samples were prepared from a 1 cm-thick equatorial disc and four sections (N, S, E, and W) were cut. Each section of flavedo, albedo, and juice sac tissue was dissected. gene expression variation underlying quality trait, different genotypes
Project description:To identify genes associated with citrus peel development and manifestation of peel disorders, we analyzed flavedo, albedo and juice sac tissues from navel orange displaying, and not displaying, the puff disorder.
Project description:To identify genes associated with citrus peel development and manifestation of peel disorders, we analyzed flavedo, albedo and juice sac tissues from navel orange displaying, and not displaying, the puff disorder. Symptomatic and healthy M-bM-^@M-^\NavelM-bM-^@M-^] orange fruits were harvested from an orchard located in in Pauma Valley, San Diego County, California, USA. Sampling for all analysis (healthy or disordered Navel orange) was performed at the same time, from trees grown under the same agronomic, soil, and environmental conditions. Healthy and disordered fruits were analyzed at the mature stage. All transcriptome analysis was performed on mature fruit. For each type of fruit, three tissues (flavedo, albedo, and juice sacs) from three different trees (biological replicates) were separately analyzed. Four symptomatic fruits comprised one biological replicate each. Two healthy fruits comprised two biological replicates of control samples. A 1 cm-thick equatorial disc and four sections (N, S, E, and W) were cut per fruit. Each section of flavedo, albedo, and juice sac tissue was dissected. gene expression variation underlying quality trait, different genotypes
Project description:Use of Information Dependent Acquisition mass spectra and Sequential Window Acquisition of all Theoretical fragment-ion mass spectra for fruit juices metabolomics and authentication. LC-MS based untargeted metabolomics are the main untargeted methods used for juice metabolomics to solve the authentication problem faced in fruit juice industry. Objectives To evaluate the performances of different untargeted metabolomics methods on fruit juices metabolomics and authentication, orange and apple fruit juices were selected for this study. Methods IDA-MS and SWATH-MS based on UHPLC-QTOF were used for the metabolomics and authenticity determination of apple and orange juices, including the lab-made samples of oranges (Citrus sinensis Osb.) from Jiangxi Province, apples (Malus domestica Borkh) from Shandong Province, and different brands of commercial orange and apple juice samples from markets. Results IDA-MS and SWATH-MS could both acquire numerous MS1 features and MS2 information of juice components, while SWATH-MS excels at the acquisition rate of MS2. Distinctive separation between authentic orange juice and not authentic orange juice could be seen from principal component analysis and hierarchical clustering analysis based on both IDA-MS and SWATH-MS. After analysis of variance, fold change analysis and orthogonal projection to latent structures discriminant mode, 53 and 46 potential markers were defined by IDA-MS and SWATH-MS (with 77.4% and 100% MS2 acquisition rate) separately. Subsequently, these potential markers were putatively annotated using general chemical databases with 6 more annotated by SWATH-MS. Furthermore, 7 of the potential markers, l-asparagine, umbelliferone, glucosamine, phlorin, epicatechin, phytosphingosine and chlorogenic acid, were identified with standards. For the consideration of model simplicity, two determined makers (umbelliferone and chlorogenic acid) were selected to construct the DD-SIMCA model in commercial samples because of their good correlation with apple adulteration proportion, and the sensitivity and specificity of the model were 100% and 95%. Conclusion SWATH-MS excels at the MS2 acquisition of juice components and potential markers. This study provides an overall performance comparison between IDA-MS and SWATH-MS, and guidance for the method selection on fruit juice metabolomics and juice authenticity determination. Two of the potential markers determined, umbelliferone and chlorogenic acid, could be used as apple juice indicators in orange juice.
Project description:Using a custom microarray platform, we examined expression of 366 genes in leaf, two peel tissues, juice sac, and whole fruit during various developmental stages of Washington Navel orange fruit (Citrus sinensis L. Osbeck). 366 genes were chosen from Citrus EST libraries by in-silico analysis method. Keywords: time course and tissue comparison

Project description:Members of the tomato clade exhibit wide diversity in fruit coloration, growth habit, leaf morphology and mating preferences. However, the mechanisms governing inter-species diversity in fruit coloration are largely unknown. Therefore, a proteomic approach combined with carotenoid profiling and carotenogenic gene expression was used to decipher the diversity in carotenogenesis in green-fruited Solanum habrochaites, orange-fruited S. galapagense, and red-fruited S. pimpinellifolium with S. lycopersicum, cv. Ailsa Craig (tomato).

Project description:Using a custom microarray platform, we examined expression of 366 genes in leaf, two peel tissues, juice sac, and whole fruit during various developmental stages of Washington Navel orange fruit (Citrus sinensis L. Osbeck). 366 genes were chosen from Citrus EST libraries by in-silico analysis method. Keywords: time course and tissue comparison Study to compare gene expression between peel layers and over time as fruit matured. Samples taken from leaf tissue, whole fruit at 24 and 38 days after full bloom (DAFB), and from albedo and flavedo layers of the peel at 80 and 165 DAFB, and flavedo from mature fruit at 220 DAFB. In all cases except one, there were three technical replicates hybridized for each Sample simultaneously.
