Project description:Berries were sample at three developmental stages (green, veraison and ripe) and flash frozen in the field in liquid nitrogen. The frozen tissue was subsequently ground in liquid nitrogen and stored at 80°C. At least three independent berry samples were collected (with n≥50 berries per sample) at three time points: at pre-véraison/green stage (Eichhorn-Lorenz (E-L) system stage 31), at véraison (E-L stage 34) and at ripe/harvest stage (E-L stage 38) Ground tissues for each developmental stage were pooled. Replicates: Separate RNA extractions were performed on aliquots of the ground tissue from each developmental stage, labeled and hybiridized to the microarrays

Project description:The experiment was aimed at describing similarities and differences between grapevine flesh and skin ripening at the transcriptome level. Transcriptional profiles throughout flesh and skin ripening were followed in three biological replicas during two consecutive growing seasons in a table grape cultivar ‘Muscat Hamburg’. Berries were weekly picked off bunches (one bunch per vine from each selected vine) from june to august. For each sampling, berries were classified in five ripening stages based on monitoring developmental stages instead of a simple chronological sampling. They corresponded to pre-véraison (P), 50% véraison (V1), 100% véraison (V2), ripe 1 (R1), and ripe 2 R2). P samples were harvested as green, hard berries of at least 15 mm in size, according to touch-assessed hardiness. Véraison berries with half or full coloured skin surface corresponded to V1 and V2 samples. After véraison, ripening berries were classified according to their floatability in solutions with different NaCl densities, as an indication of the internal sugar concentration. At this stage berries were sampled with densities between 110-130 g NaCl/L for R1 and between 130-150 g NaCl/L for R2, which corresponded to commercially ripen table grape berries. On each of the five samples, frozen berries were dissected and RNA from flesh and skin was obtained and processed for Grapegen Genechip microarray hybridizations. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Pablo Carbonell-Bejerano.

Project description:Studying the effect of varying durations (1, 7 and 14 days) of locally applied heat stress on grape berries at three developmental stages (middle green, veraison and middle ripening). Among various environmental factors, temperature is a major regulator affecting plant growth, development and fruit composition. Reproductive development of grapevine and berry composition, are both highly influenced by temperature. To date, the molecular mechanisms involved in grapevine berries tolerance to high temperatures (HS) are poorly understood. Although recent data addressed the consequences on berry development of elevated temperatures applied at the whole plant level, the present work particularly focuses on the fruit responses triggered by direct exposure to heat stress. In the context of climate change, this work focused on microclimate effect is of particular interest to better understand the consequences of leaf removal (a common viticultural practice) on berry development. HS (+ 8°C) was locally applied to clusters from Cabernet Sauvignon fruiting cuttings at three different developmental stages (middle green, véraison and middle ripening). Samples were collected 1, 7 and 14 days after treatment and used for metabolic and transcriptomic analyses. The results showed dramatic and specific biochemical and transcriptomic changes in heat exposed berries, depending on the developmental stage and the stress duration. When applied at the herbaceous stage, HS delayed the onset of véraison. Heating also strongly altered the berry concentration of amino acids and organic acids (e.g. PHE, GABA, and malate) and decreased the anthocyanin content at maturity. These physiological alterations could be partly explained by the deep remodelling of transcriptome in heated berries. More than 7000 genes were deregulated in at least one of the nine experimental conditions. The most affected processes belong to the categories “stress responses”, “protein metabolism” and “secondary metabolisms”, highlighting the intrinsic capacity of grape berries to perceive heat stress and to build adaptive responses. Additionally, important changes in processes related to “transport”, “hormone” and “transcription” might contribute to the postponing of véraison. Finally, opposite effects depending on heating duration were observed for genes encoding enzymes of the general phenylpropanoid pathway, suggesting that the HS-induced decrease in anthocyanin content may result from a combination of transcript abundance and product degradation.

Project description:A bunch of grapes at veraison is comprised of berries at different stages of development ranging from hard green to soft ripe red. Veraison represents an important transition stage in the ripening process where key genes may be switched on or off. Single berries at various stages of development from hard green to ripe red were collected at a single time point from a single bunch of grapes going through veraison. Gene expression patterns were obtained from single berries representing different developmental stages. Keywords: Developmental series

Project description:Blueberry is one of the most desirable and nutritious fruits. During fruit development, the blueberry’s organoleptic properties and phytonutrient composition are ever-changing [1]. Blueberry fruit development is typically described in five phases: pads, cups, green, pink, and blue (ripe) [2]. The former two phases are referred to as the initial “expansion”. During expansion, young fruit is generally hard, dark green and distinguishable by size [3]. The latter three phases are referred to as maturation. Green fruit are hard and fully rounded green berries; pink berries are partially pigmented; blue (ripe) berries are fully colored and soft. Fruit maturation has attracted considerable research attention, and typically, the characteristics fruit softening, coloring, and sweetening are assessed [4].

Project description:The study investigated protein dynamics throughout fruit developmental and ripening process of blue-colored bilberry. The proteomic approach was applied to study at four different ripening stages, S2-small green fruit, S3- large green fruit, S4- purple ripening fruit, S5- ripe, blue fruit of bilberry. Regulatory network of plant hormones and physiological processes occurring during bilberry fruit ripening was revealed for the first time. The white-colored mutant bilberry, at the ripe stage, was also investigated differences compared to wild, blue-colored berries.

Project description:The role of photosynthesis in fruits still challenges scientists. This is especially true in the case of mature grape berries of red varieties lined by an anthocyanin-enriched exocarp (skin) almost impermeable to gases. Although chlorophylls are degraded and replaced by carotenoids in several fruits, available evidence suggests that they may persist in red grapes at maturity. In the present study, chloroplasts were isolated from the skin of red grape berries (cv. Vinhão) to measure chlorophyll levels and the organelle proteome. The results showed that chloroplasts (and chlorophylls) are maintained in ripe berries masked by anthocyanin accumulation and that the proteome of chloroplasts from green and mature berries is distinct. Several proteins of the light reactions significantly accumulated in chloroplasts at the mature stage, including those of light-harvesting complexes of photosystems I (PSI) and II (PSII), redox chain, and ATP synthase, while chloroplasts at the green stage accumulated more proteins involved in the Calvin cycle and the biosynthesis of amino acids, including precursors of secondary metabolism. Taken together, results suggest that although chloroplasts are more involved in biosynthetic reactions in green berries, at the mature stage, they may provide ATP for energy-demanding processes such as anthocyanin biosynthesis or even O2 to feed the respiratory demand of inner tissues.
