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: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.

Project description:Pseudomonas syringae pv. syringae 9644 (Pss9644) is a causal agent of bacterial cherry canker causing necrotic symptoms on leaves, fruits, gummosis and canker in woody tissues of sweet cherry (Prunus avium). To understand which virulent factor genes were expressed in vitro, Pss9644 was grown in rich media (King's B Broth) and minimum media (hrp-inducing minimum media). The latter mimics the in planta environment.

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 ca. 60 days post-anthesis over three consecutive years (2016-2017-2018).

Project description:Using sRNA-Seq to provide small RNA status in fruit ripening stages in sweet orange DNA methylation is an important epigenetic mark involved in many biological processes. The genome of the climacteric tomato fruit undergoes a global loss of DNA methylation due to active DNA demethylation during the ripening process. It is unclear whether the ripening of other fruits is also associated with global DNA demethylation. We characterized the single-base resolution DNA methylomes of sweet orange fruits. Compared to immature orange fruits, ripe orange fruits gained DNA methylation at over 30,000 genomic regions and lost DNA methylation at about 1,000 genomic regions, suggesting a global increase in DNA methylation during orange fruit ripening. This increase in DNA methylation was correlated with decreased expression of DNA demethylase genes. The application of a DNA methylation inhibitor interfered with ripening, indicating that the DNA hypermethylation is critical for the proper ripening of orange fruits. We found that ripening-associated DNA hypermethylation was associated with the repression of several hundred genes, such as photosynthesis genes, and with the activation of hundreds of genes including genes involved in ABA responses. Our results suggest important roles of DNA methylation in orange fruit ripening.

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:Fleshy fruit help in reproduction by developing structures that, reached a given maturity stage, become attractive to animals that, feeding on them, spread the contained seeds in the environment. According to the species, seed development can be at the same pace with the pericarp, or be ready for dispersion before or after the ripening of the fruit. In peach, seed and mesocarp maturation are on pace in mid-season cultivars, while in early ripening ones the seed is not mature at ripening, with the endosperm not yet fully reabsorbed. On the contrary, slow ripening genotypes show the opposite, i.e. a mature seed in a fruit unable to fully ripen. To gain insights on the molecular control of peach fruit development and ripening and on the interactions between the seed and the mesocarp, genome wide transcriptional changes of the two fruit parts have been investigated throughout development from flower anthesis up to commercial ripening in the mid-season cultivar Fantasia. Besides flower, six time points encompassing the four fruit developmental stages were investigated.

Project description:Kumquat (Fortunella classifolia Swingle) was thought as a close relative to citrus according to fruit morphology taxonomic, but kumquat fruit as well as its flowering characteristic are distinct from other citrus species, the trees usually blooms on the medium of June, obviously later than other citrus species, moreover many kumquat accessions could be blossom more than one times during one growth season, as this reason, the kumquat fruits could be consecutively ripen over several months, which made the study of globe genes expression profile for different development stage fruit easy. Kumquat is non-climacteric fruit, however the kumquat fruit ripening process, especially genes expression change in young and ripe kumquat fruits are less known, so studying on the global genes expression profiles of kumquat fruits in young and ripe stage are especially helpful to identify ripening-related genes and unravel the mechanism of ripening process.
