“…Ruffner et al . (1976) [102] reported an increase in PEPCK activity in ripening grapes which coincides with two PEPCK transcripts found by Terrier et al (2005) [12]. In microvine berries two PEPCKs were consistently up-regulated throughout development ( VIT_00s2840g00010, VIT_07s0205g00070 ; cluster 8; Table S5).…”

Is Transcriptomic Regulation of Berry Development More Important at Night than During the Day?

Diurnal changes in gene expression occur in all living organisms and have been studied on model plants such as Arabidopsis thaliana. To our knowledge the impact of the nycthemeral cycle on the genetic program of fleshly fruit development has been hitherto overlooked. In order to circumvent environmental changes throughout fruit development, young and ripening berries were sampled simultaneously on continuously flowering microvines acclimated to controlled circadian light and temperature changes. Gene expression profiles along fruit development were monitored during both day and night with whole genome microarrays (Nimblegen® vitis 12x), yielding a total number of 9273 developmentally modulated probesets. All day-detected transcripts were modulated at night, whereas 1843 genes were night-specific. Very similar developmental patterns of gene expression were observed using independent hierarchical clustering of day and night data, whereas functional categories of allocated transcripts varied according to time of day. Many transcripts within pathways, known to be up-regulated during ripening, in particular those linked to secondary metabolism exhibited a clearer developmental regulation at night than during the day. Functional enrichment analysis also indicated that diurnally modulated genes considerably varied during fruit development, with a shift from cellular organization and photosynthesis in green berries to secondary metabolism and stress-related genes in ripening berries. These results reveal critical changes in gene expression during night development that differ from daytime development, which have not been observed in other transcriptomic studies on fruit development thus far.

“…This is in partial agreement with a previous study showing that titratable acidity was affected by season in a polycarbonate greenhouse, with a decrease in the autumn cycle culture compared to the spring cycle (Anza et al 2006) under climatic conditions different from those of the present study since the experiment was located in Spain. These differences could be related to changes in solar radiation and temperature with their impact on source-sink relationships (Baldet et al 2002) in relation with temperature influence on activities of enzymes such as sucrose synthase (Rosales et al 2007) or malic enzyme (Ruffner et al 1976(Ruffner et al , 1984. Valine was higher in March-May samples in the present experiment.…”

Proton NMR quantitative profiling for quality assessment of greenhouse-grown tomato fruit

et al. 2009

Tomato is an essential crop in terms of economic importance and nutritional quality. In France, the third most important region for tomato (Solanum lycopersicum L.) production is Aquitaine where the major part of production is now grown soilless under greenhouse conditions with harvest from March to November. Tomato fruit quality at harvest is a direct function of its metabolite content at that time. The aim of this work was to use a global approach to characterize changes in the fruit organoleptic quality at harvest under commercial culture conditions during an entire season for two varieties and two different fertilization practices (with or without recycling of the nutrient solution) for one variety. Absolute quantification data of 32 major compounds in fruit without seeds were obtained through untargeted (proton nuclear magnetic resonance, 1 H-NMR) quantitative profiling. These data were complemented by colorimetric analysis of ascorbate and total phenolics. They were analyzed with chemometric approaches. Principal component analysis (PCA) or partial least square analyses (PLS) revealed more discriminant metabolites for season than for variety and showed that nutrient solution recycling had very little effect on fruit composition. These tendencies were confirmed with univariate analyses. 1 H-NMR profiling complemented with colorimetric analyses therefore provided a diagnostic tool to follow the changes in organoleptic and nutritional quality of tomato. In addition the quantitative information generated will help to increase our knowledge on the mechanisms of plant response to environmental modifications.Electronic supplementary material The online version of this article (

“…Or, Baybik, Sadka, and Saks () suggested that the control of malate metabolism throughout growth of grape berries involves developmental regulation of phosphoenolpyruvate carboxylase, malate dehydrogenase, and malic enzyme transcript availability. Earlier, in the studies conducted on grapes ( Vitis vinifera L.), enzymes involved in malate metabolism were reported to respond differently to temperature in berries at different development stages (Lakso & Kliewer, ; Ruffner, Hawker, & Hale, ). A study on tomato fruits of Solanum lycopersicum L. cv.…”

Regulation of phytochemicals in fruits and berries by environmental variation—Sugars and organic acids

et al. 2018

View full text Add to dashboard Cite

Sugars and organic acids are important phytochemicals contributing to the nutrition and sensory properties of fruits and berries. Their contents are closely correlated to the genetic background of plants as well as to the environmental conditions during growth. This review focuses on the recent researches on the metabolism of these compounds in fruits and berries in response to the variation of environmental conditions, including temperature, radiation, and water supply. A great deal of investigations indicates that the influence of environmental factors on the composition of fruits/berries depended largely on the genetic background. Moreover, the metabolic regulation in response to environmental changes also varies between different plant developmental stages. Nevertheless, some general trends, like the positive correlation between light intensity and sugar content, were observed in most investigations. In grapes (Vitis vinifera L.), the content of malic acid always decreases as light intensity increases, and as the water supply decreases. Practical applications The contents of sugars and organic acids, and especially their relative ratio, are important indicators determining the taste and quality of fruits and fruit products. In this review, we summarized the investigations carried out on the regulation of these sensory contributing primary metabolites in fruits and berries in relation to the variation of environmental conditions. It was indicated that various factors, such as plant genotype, growing period, and interaction between environmental factors, might contribute to the impact of environmental changes on the composition of fruits/berries. The article not only provides comprehensive knowledges in food chemistry and plant physiology but also provide important background knowledge for berry cultivation and breeding, as well as useful guidelines for utilization of fruits and berries in food industry.
