Abstract Fruit from rosaceous species collectively display a great variety of flavors and textures as well generally high content nutritionally beneficial metabolites. However, relatively little analysis metabolic networks in fruit has been reported. Among species, peach (Prunus persica) stone fruits composed juicy mesocarp lignified endocarp. Here, were studied across development using metabolomics key regulatory enzymes. Principal component composition revealed clear shifts early through...
Abstract BACKGROUND: Strawberry is a soft fruit, considered as non‐climacteric, being auxins the main hormones that regulate ripening process. The role of ethylene in strawberry currently unclear and several studies have revision possible this hormone. RESULTS: fruit were harvested at white stage treated with ethephon, an ethylene‐releasing reagent, or 1‐methylcyclopropene (1‐MCP), competitive inhibitor action. effects treatments on quality parameters activity enzymes related to anthocyanin...
Reconfiguration of the metabolome is a key component involved in acclimation to cold plants; however, few studies have been devoted analysis overall metabolite changes after storage fruits prior consumption. Here, profiling six peach varieties with differential susceptibility develop mealiness, chilling-injury (CI) symptom, was performed. According metabolic content at harvest; treatment; and ripening, either following treatment or not; clustered distinct groups, depending on harvest-time,...
Peaches are highly perishable and deteriorate quickly at ambient temperature. Cold storage is commonly used to prevent fruit decay; however, it affects quality causing physiological disorders collectively termed 'chilling injury' (CI). To or ameliorate CI, heat treatment often applied prior cold storage. In the present work, metabolic profiling was performed determine dynamics associated with induction of acquired CI tolerance in response shock. 'Dixiland' peach fruits exposed 39 °C, stored,...
In strawberry, the putative participation of aquaporins should be considered during fruit ripening. Furthermore, availability different firmness cultivars in this non-climacteric is a very useful tool to determine their involvement softening. previous work, cloning strawberry fruit-specific aquaporin, FaPIP1;1, which showed an expression profile associated with ripening was reported. Here, FaPIP2;1, aquaporin subtype PIP2 cloned and its functional characterization Xenopus oocytes determined....
Despite the advances in physiology of fruit ripening, role and contribution water pathways are still barely considered. Our aim was therefore to characterize aquaporins, proteins that render molecular basis for putative regulatory mechanisms transport. We focused our work on strawberry ( Fragaria × ananassa ) fruit, a non‐climacteric special interest because its forced brief commercial shelf life. A full‐length cDNA isolated with high homology plasma membrane (PM) intrinsic (named FaPIP1;1),...
Cold storage is extensively used to slow the rapid deterioration of peach (Prunus persica L. Batsch) fruit after harvest. However, subjected long periods cold develop chilling injury (CI) symptoms. Post-harvest heat treatment (HT) prior effective in reducing some CI symptoms, maintaining quality, preventing softening and controlling post-harvest diseases. To identify molecular changes induced by HT, which may be associated protection, differential transcriptome HT was characterized display...
Peaches ripen and deteriorate rapidly at room temperature. Therefore, refrigeration is used to slow these processes extend fruit market life; however, many fruits develop chilling injury (CI) during storage low Given that cell membranes are likely sites of the primary effects chilling, lipidome six peach varieties with different susceptibility CI was analyzed under postharvest conditions. By using liquid chromatography coupled mass spectrometry (LC–MS), 59 lipid species were detected,...
Peach (Prunus persica) is an important economically temperate fruit. The development follows double sigmoid curve with four phases (S1-S4). We centered our work in the early development. In addition to S1, we studied very stage (E) characterized by lag zone of exponential growing phase and second (S2) when pit starts hardening. "Dixiland" peach fruit were collected at 9 (E), 29 (S1), 53 days after flowering (DAF) endocarp mesocarp separated. There was a pronounced decrease total protein...
Peach Leaf Curl Disease, caused by Taphrina deformans, is characterized reddish hypertrophic and hyperplasic leaf areas. To comprehend the biochemical imbalances fungus, dissected symptomatic (C) asymptomatic areas (N) from leaves with increasing disease extension were analyzed an integrated approach including metabolomics, lipidomics, proteomics, complementary techniques. Drastic metabolic differences identified in C respect to either N or healthy leaves, altered chloroplastic functioning...
Leaf peach curl is a devastating disease affecting leaves, flowers and fruits, caused by the dimorphic fungus Taphrina deformans. To gain insight into mechanisms of pathogenesis plant responses, leaves resistant two susceptible Prunus persica genotypes were inoculated with blastospores (yeast), infection was monitored during 120 h post inoculation (h.p.i.). Fungal dimorphism to filamentous form induction reactive oxygen species (ROS), callose synthesis, cell death defence compound production...
The suitability of commercial peaches for minimal processing (MP) is limited, mainly due to shortened shelf-life. Gamma irradiation has emerged in MP fruits as a promising technology. This study aimed investigate the effects gamma on sensory and metabolic profiles from two cultivars - 'Forastero' (FT) 'Ruby Prince' (RP) evaluate relationship between both profiles. were packaged divided into groups: one without additional treatment (K) other subjected (1.0 kGy, I- treatment), making total...
Chromatin assembly factor-1 (CAF-1) is a histone H3/H4 chaperone that participates in DNA and chromatin interaction processes. In this manuscript, we show organs from CAF-1 deficient plants respond differently to ultraviolet-B (UV-B) radiation than other genotoxic stresses. For example, leaves tolerate better UV-B radiation, showing lower cyclobutane pyrimidine dimer (CPD) accumulation, inhibition of cell proliferation, increased wall thickness, absorbing compounds, ploidy levels, whereas...
Peach Leaf Curl Disease, caused by the fungus Taphrina deformans, is characterized reddish hypertrophic and hyperplasic leaf areas. To comprehend biochemical imbalances disease an integrated approach including metabolomics, lipidomics, proteomics complementary techniques was undertaken. Symptomatic asymptomatic areas were dissected from leaves with increasing extension of disease. A differential metabolic behaviour identified in symptomatic respect to either or healthy leaves. showed altered...
