Project description:Our experiments show that exogenous MT treatment can effectively delay the decay and water loss rate of post-harvest wax apples, which may be related to reducing the degree of membrane lipid peroxidation and inhibiting enzymatic browning. MT treatment also maintains the quality of post-harvest wax apple by enhancing the activity of antioxidant enzymes. At the same time, it can reduce the incidence of post-harvest diseases of wax apple by increasing the JA and SA contents. MT can down-regulate the expression of genes related to oxidation, and up-regulate the expression of related genes in antioxidant enzymes and non-enzymatic antioxidant pathways, suggesting that exogenous melatonin can reduce the production of excess ROS and maintain the redox homeostasis of post-harvest wax apple. Therefore, melatonin, as a strong and effective free radical scavenger and antioxidant, plays an important role in delaying the decay of post-harvest wax apples and prolonging the shelf life.

Project description:Based on sensorial analysis over 4 years, 6 apple genotypes with contrasted fruit texture (mealy or not) were selected among a progeny. Apple samples were collected at 100 days after flowering (100 DAF), harvest (H), after 2 and 4 months of cold storage (60DAH and 120DAH respectively).

Project description:Based on sensorial analysis over 4 years, 6 apple genotypes with contrasted fruit texture (mealy or not) were selected among a progeny. Apple samples were collected at 100 days after flowering (100 DAF), harvest (H), after 2 and 4 months of cold storage (60DAH and 120DAH respectively). 6 apple hybrids were analysed in dye-switch. Biological replicates are fruits from 2 to 4 different harvest years. Each mealy hybrid was compared to a non-mealy hybrid from the same harvest year in 12 dye-swap 3 pairs at 4 four time points).

Project description:Based on sensorial analysis, 8 apple genotypes with contrasted fruit texture for mealiness were selected among a progeny. Apple samples were collected at 60 days after flowering (60DAF), 110 days after flowering (110DAF), harvest (Rec), and after 1 or 2 months of cold storage (1M and 2M respectively).

Project description:Apple (Malus x domestica Borkh.) is a model fruit species to study the metabolic changes occurring at the onset of ripening as well the physiological mechanism governed by the hormone ethylene. In this survey, to dissect the climacteric interplay in apple, a multidisciplinary approach was employed. To this end, a comprehensive analysis of gene expression together with the investigation of several physiological entities (texture, volatilome and polyphenolic compounds) was carried out throughout fruit development and ripening. The transcriptomic profiling was conducted with two microarray platforms, a custom array dedicated to fruit ripening pathways (iRIPE) and a whole genome array specifically enriched of ripening related genes for apple (WGAA). The transcriptomic and phenotypic changes following the application of 1-methylcyclopropene (1-MCP), an ethylene inhibitor, were also highlighted. The suppression of ethylene modified and delayed the ethylene receptors turnover, leading to important modifications in the overall fruit physiology. The integrative comparative network analysis showed both negative and positive correlations between ripening related transcripts and accumulation of specific metabolites or texture components. The ripening distortion caused by the inhibition of the ethylene perception besides affecting the ethylene and texture control, stimulated the de-repression of auxin related genes, transcription factors and photosynthethic genes. In the end, the comprehensive repertoire of results obtained here step forwards in the elucidation of the multi-layered control of ethylene, hypothesizing a possible hormonal cross-talk coupled with a transcriptional regulation. 48 samples analyzed; 8 stages have been identified over the fruit development and ripening (from flower to post harvest ripening) of apple fruit belonging to two apple cultivars (Golden Delicious and Granny Smith), ending with 16 samples (3 replacates for each sample)

Project description:Here, we conducted an tandem mass tag (TMT)-based proteomics analysis of apple fruit development over five growth stages. Our objective was to gain a global overview of the dynamics of apple fruit development and identify key regulatory networks and proteins that contribute to fruit development and the metabolism and accumulation of sugars and acids for fruit quality improvement.

Project description:Molecular events regulating apple fruit ripening and sensory quality are largely unknown. Such knowledge is essential for genomic-assisted apple breeding and postharvest quality management. In this study, a parallel transcriptome profile analysis, scanning electron microscopic (SEM) examination and systematic physiological characterization were performed on two apple cultivars, Honeycrisp (HC) and Cripps Pink (CP), which have distinct ripening features and texture attributes. Systematic physiological characterization of fruit ripening based on weekly maturity data indicated substantial differences in fruit crispness and firmness at comparable ripening stages. SEM images of fruit cortex tissues prepared from fruits with equivalent maturity suggested that the cell wall thickness may contribute to the observed phenotypes of fruit firmness and crispness. A high-density long-oligo apple microarray consisting of duplex 190,135 cross-hybridization-free 50-70-mer isothermal probes, and representing 23,997 UniGene clusters, was manufactured on a Nimblegen array platform. Transcriptome profiling identified a total of 1793 and 1209 UniGene clusters differentially expressed during ripening from cortex tissues of HC and CP, respectively. UniGenes implicated in hormone metabolism and response, cell wall biosynthesis and modification and those encoding transcription factors were among the prominent functional groups. Between the two cultivars, most of the identified UniGenes were similarly regulated during fruit ripening; however, a short list of gene families or specific family members exhibited distinct expression patterns between the two cultivars, which may represent candidate genes regulating cultivar-specific apple fruit ripening patterns and quality attributes.
