Project description:The experiment was performed in a commercial sweet cherry (cv. Tsolakeika, Prunus avium L.) orchard in North Greece (Edessa) during 2017 growing season. The orchard contained 10-years old trees, planted at 5x5 m spacing between rows and along the row, grafted onto Mahaleb cherry (Prunus mahaleb L.) rootstock, trained in open vase and subjected to standard cultural practices. Three foliar sprays (0.5% or 35 mM CaCl2) were performed at 15, 27 and 37 days after full blossom (DAFB). Cherry fruits (exocarp plus mesocarp tissues) were sampled in two developmental stages, namely at full red color (44 DAFB, S4 stage) and at commercial harvest (55 DAFB, S5 stage). Three biological replicates of 20-fruit sub-lots in control and Ca-treated fruits were frozen in liquid nitrogen, grinding in fine powder and stored at -80 ⁰C for proteomic processing.

Project description:Bud dormancy is a crucial stage in perennial trees and allows survival over winter and optimal subsequent flowering and fruit production. Environmental conditions, and in particular temperature, have been shown to influence bud dormancy. Recent work highlighted some physiological and molecular events happening during bud dormancy in trees. However, we still lack a global understanding of transcriptional changes happening during bud dormancy. We conducted a fine tune temporal transcriptomic analysis of sweet cherry (Prunus avium L.) flower buds from bud organogenesis until the end of bud dormancy using next-generation sequencing. We observe that buds in organogenesis, paradormancy, endodormancy and ecodormancy are characterised by distinct transcriptional states, and associated with different pathways. We further identified that endodormancy can be separated in two phases based on its transcriptomic state: early and late endodormancy. We also found that transcriptional profiles of just 7 genes are enough to predict the main cherry tree flower buds dormancy stages. Our results indicate that transcriptional changes happening during dormancy are robust and conserved between different sweet cherry cultivars. Our work also sets the stage for the development of a fast and cost effective diagnostic tool to molecularly define the flower bud stage in cherry trees.

Project description:Samples from fruit juice vesicle tissue from three lemon genotypes (Frost Lisbon, Faris "sour" and Faris "sweet") differing in fruit acidity were compared at two developmental timepoints (immature, mature). Faris lemon appears to be a graft chimera with the L2 layer derived from normal acid lemon and layer L1 from Millsweet limetta or a closely related genotype. Fruit of Faris sour and Faris sweet grew on different branches of the same tree, with sour fruit developing on branches with L1 and L2 from acid lemon. genotype: Faris sweet lemon - developmental stage: PO:0007009 FF.01 fruit size 30%,(3-replications); genotype: Faris sweet lemon - developmental stage: PO:0007050 FR.03 late stage of fruit ripening,(3-replications); genotype: Faris acid lemon - developmental stage: PO:0007009 FF.01 fruit size 30%,(3-replications); genotype: Faris acid lemon - developmental stage: PO:0007050 FR.03 late stage of fruit ripening,(3-replications); genotype: Frost Lisbon lemon - developmental stage: PO:0007009 FF.01 fruit size 30%,(3-replications); genotype: Frost Lisbon lemon - developmental stage: PO:0007050 FR.03 late stage of fruit ripening,(3-replications) PLEXdb (http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Mikeal L. Roose. The equivalent experiment is CT1 at PLEXdb.

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.

Project description:Sweet cherry (Prunus avium L.) is a stone fruit widely consumed and appreciated for its organoleptic properties, as well as its nutraceutical potential. We here investigated the characteristics of six non-commercial Tuscan varieties of sweet cherry maintained at the Regional Germplasm Bank of the CNR-IBE in Follonica (Italy) and sampled at maturity over three consecutive years (2016-2017-2018). We adopted an approach merging genotyping and targeted gene expression profiling with metabolomics. To complement the data, a study of the soluble proteomes was also performed on two varieties showing the highest content of phenolics. The results obtained revealed that the highest differences were observed in the expression of genes involved in the phenylpropanoid pathway during the three years and among the varieties, while metabolomics identified the presence of flavanols and proanthocyanidins in highest abundance in the varieties Morellona and Crognola. Finally, proteomics on these two varieties showed differences in proteins involved in stress response, primary metabolism, and cell wall expansion. To the best of our knowledge, this is the first multi-pronged study focused on Tuscan sweet cherry varieties providing insights into the differential abundance of genes, proteins and metabolites.
