“…Mango peel is considered a major location of polyphenols within the whole fruit . In agreement with the previous report by Kim et al ., the concentrations of total phenols in the peel were 36‐ and 8‐fold higher than pulp in ‘Kensington Pride’ and ‘R2E2’ mangoes, respectively.…”

“…There is extensive information regarding the ripening physiology (Bulens et al 2014) due to its biological, nutritional, and economical value. Except for a recent report on its predicted plastid proteome (Schaeffer et al 2014), not much is known about the novel proteomic or metabolomic constitution of apple plastids, which carry out important biochemical processes.…”

Plastids are the defining organelle for a plant cell and are critical for myriad metabolic functions. The role of leaf plastid, chloroplast, is extensively documented; however, fruit plastids—chromoplasts—are poorly understood, especially in the context of the diverse metabolic processes operating in these diverse plant organs. Recently, in a comparative study of the predicted plastid-targeted proteomes across seven plant species, we reported that each plant species is predicted to harbor a unique set of plastid-targeted proteins. However, the temporal and developmental context of these processes remains unknown. In this study, an ultrastructural analysis approach was used to characterize fruit plastids in the epidermal and collenchymal cell layers at 11 developmental timepoints in three genotypes of apple (Malus × domestica Borkh.): chlorophyll-predominant ‘Granny Smith’, carotenoid-predominant ‘Golden Delicious’, and anthocyanin-predominant ‘Top Red Delicious’. Plastids transitioned from a proplastid-like plastid to a chromoplast-like plastid in epidermis cells, while in the collenchyma cells, they transitioned from a chloroplast-like plastid to a chloro-chromo-amyloplast plastid. Plastids in the collenchyma cells of the three genotypes demonstrated a diverse array of structures and features. This study enabled the identification of discrete developmental stages during which specific functions are most likely being performed by the plastids as indicated by accumulation of plastoglobuli, starch granules, and other sub-organeller structures. Information regarding the metabolically active developmental stages is expected to facilitate biologically relevant omics studies to unravel the complex biochemistry of plastids in perennial non-model systems.

“…CA reduces respiration and ethylene production, and preserves firmness and color of apples (Kader , Herregods ). Furthermore, previous studies conducted on specific segments of the metabolic pathway demonstrated the diverse and broad effect of O 2 and CO 2 in the electron transport chain (Nanos and Kader , Saquet et al ), glycolysis (Kerbel et al ), tricarboxylic acid (TCA) cycle (Shipway and Bramlage ), ethanolic fermentation (Ke et al ), Yang cycle (Bulens et al ) and amino acid metabolism (Hansen et al ). Low O 2 storage reduces cytosolic pH and energy charge of pears (Nanos and Kader ) and apples (Saquet et al ).…”

“…1‐MCP treatment combined with CA storage is more effective in maintaining the firmness of the fruit than 1‐MCP treatment with regular air (RA) storage (Watkins et al ). However, the efficacy of 1‐MCP depends on several factors such as cultivar, degree of maturity, treatment temperature and storage temperature and duration (DeEll et al , Blankenship and Dole , Bulens et al ). Also, 1‐MCP negatively influences aroma production (Ferenczi et al ), can have a positive, negative or negligible effect on soluble solid concentration (SSC) content (Watkins ), and increases the CO 2 injury (Fawbush et al ) and flesh browning of some apple cultivars such as ‘Empire’ apple (Jung and Watkins ).…”

Apples are predominantly stored in controlled atmosphere (CA) storage to delay ripening and prolong their storage life. Profiling the dynamics of metabolic changes during ripening and CA storage is vital for understanding the governing molecular mechanism. In this study, the dynamics of the primary metabolism of 'Jonagold' apples during ripening in regular air (RA) storage and initiation of CA storage was profiled. 1-Methylcyclopropene (1-MCP) was exploited to block ethylene receptors and to get insight into ethylene mediated metabolic changes during ripening of the fruit and in response to hypoxic stress. Metabolic changes were quantified in glycolysis, the tricarboxylic acid (TCA) cycle, the Yang cycle and synthesis of the main amino acids branching from these metabolic pathways. Partial least square discriminant analysis of the metabolic profiles of 1-MCP treated and control apples revealed a metabolic divergence in ethylene, organic acid, sugar and amino acid metabolism. During RA storage at 18°C, most amino acids were higher in 1-MCP treated apples, whereas 1-aminocyclopropane-1-carboxylic acid (ACC) was higher in the control apples. The initial response of the fruit to CA initiation was accompanied by an increase of alanine, succinate and glutamate, but a decline in aspartate. Furthermore, alanine and succinate accumulated to higher levels in control apples than 1-MCP treated apples. The observed metabolic changes in these interlinked metabolites may indicate a coordinated adaptive strategy to maximize energy production.
