Project description:Grapevine is a commercially important fruit crop that provides berries for direct consumption, juice pressing, drying (raisins), and fermentation to produce wine. The economic value of the crop has encouraged many researchers to study the physiological and molecular basis of berry development, particularly processes that affect wine quality. Post-harvest withering of grapevine berries is used in the production of dessert and fortified wines to alter must quality characteristics and to increase the concentration of simple sugars. Vitis vinifera cv Corvina berries were sampled during the 2006 growing season at four developmental time points and three additional time points during the 91-day post-harvest withering process. The four developmental time points were 59, 71, 98 and 112 days after fruit set, corresponding to pre-veraison, veraison, early ripening and late ripening, and the three withering time points (WI, WII and WIII) were 35, 56 and 91 days after harvest. Three biological replicates were taken at each time point resulting in a total of 21 samples.

Project description:Manipulating the crop load in peach trees determines carbon supply and optimum balance between fruit yield and quality potentials. The impact of carbon supply on peach fruit quality was assessed in three development stages (S2, S3, S4) on fruit of equal maturity from trees that were carbon (C) starved (unthinned) and sufficient (thinned). Previous studies determined that primary metabolites of peach fruit mesocarp are mainly linked with developmental processes, thus, the secondary metabolite profile was assessed using non-targeted liquid chromatography mass-spectrometry (LC-MS). Carbon sufficient (C-sufficient) fruit demonstrated superior quality attributes as compared to C-starved fruit. Early metabolic shifts in the secondary metabolome appear to prime quality at harvest. Enhanced C-availability facilitated the increased and consistent synthesis of flavonoids, like catechin, epicatechin and eriodyctiol, via the phenylpropanoid pathway, providing a link between the metabolome and fruit quality, and serving as signatures of C-sufficiency during peach fruit development.

Project description:Background: While the luminal microbiome composition in the human cervicovaginal tract has been defined, the presence and impact of tissue-adherent ectocervical microbiota remain incompletely understood. Studies of luminal and tissue-associated bacteria in the gastrointestinal tract suggest that they may have distinct roles in health and disease. Here, we performed a multi-omics characterization of paired luminal and tissue samples collected from a clinically well-characterized cohort of Kenyan women. Results: We identified a tissue-adherent bacterial microbiome, with a higher alpha diversity than the luminal microbiome, in which dominant genera overall included Gardnerella and Lactobacillus, followed by Prevotella, Atopobium, and Sneathia. About half of the L. iners dominated luminal samples had a corresponding Gardnerella dominated tissue microbiome. Broadly, the tissue-adherent microbiome was associated with fewer differentially expressed host genes than the luminal microbiome. Gene set enrichment analysis revealed that L. crispatus-dominated tissue-adherent communities were associated with protein translation and antimicrobial activity, whereas a highly diverse microbiome was associated with epithelial remodeling and pro-inflammatory pathways. Communities dominated by L. iners and Gardnerella were associated with low host transcriptional activity. Tissue-adherent microbiomes dominated by Lactobacillus and Gardnerella correlated with host protein profiles associated with epithelial barrier stability, and with a more pro-inflammatory profile for the Gardnerella-dominated microbiome group. Tissue samples with a highly diverse composition had a protein profile representing cell proliferation and pro-inflammatory activity. Conclusion: We identified ectocervical tissue-adherent bacterial communities in all study participants. These communities were distinct from cervicovaginal luminal microbiota in a significant proportion of individuals. This difference could possibly explain that L. iners dominant luminal communities have a high probability of transitioning to high diverse bacterial communities including high abundance of Gardnerella. By performing integrative multi-omics analyses we further revealed that bacterial communities at both sites correlated with distinct host gene expression and protein levels. The tissue-adherent bacterial community is similar to vaginal biofilms that significantly impact women’s reproductive and sexual health.

Project description:Background: Anthocyanins are the most important compounds for nutritional quality and economic values of blood orange. However, there are few reports on the pre-harvest treatment accelerate the accumulation of anthocyanins in postharvest blood orange fruit. Here, we performed a comparative Transcriptome and metabolomics analysis to elucidate the underlying mechanism involved in seasonal drought (SD) treatment during fruit expansion stage on anthocyanin accumulation in postharvest ‘Tarocco’ blood orange fruit. Results: Our results showed that SD treatment slowed down the fruit enlargement and increased the sugar accumulation during fruit development and matured period. Obviously, under SD treatment, the accumulation of anthocyanin in blood orange fruit during postharvest storage was significantly accelerated and markedly higher than that in CK. Meanwhile, the total flavonoids and phenols contents and antioxidant activity in SD treatment fruit were also sensibly increased during postharvest storage. Based on metabolome, we found that substrates required for anthocyanin biosynthesis, such as amino acids and their derivatives, and phenolic acids, have significantly accumulated and higher in SD treated mature fruit compared with that of CK. Further according to the results of transcriptome data and weighted gene coexpression correlation network analysis (WGCNA) analysis, phenylalanine ammonia-lyase (PAL3) was considered key structural gene. qRT-PCR analysis verified that the PAL3 was highly expressed in SD treated postharvest stored fruit and was significantly positively correlated with the anthocyanin content. Moreover, we found that other structural genes in anthocyanin biosynthesis pathway were also upregulated under SD treatment through transcriptome data and qRT-PCR analysis. Conclusions: The findings suggest that SD treatment promotes the accumulation of substrates necessary for anthocyanin biosynthesis during fruit ripening process, and activates the expression of anthocyanin biosynthesis pathway genes during postharvest storage period, especially PAL3, co-contributed to the rapid accumulation of anthocyanin. The present study provides a theoretical basis for postharvest quality control and water-saving utilization of blood orange fruit.

Project description:Fig fruit are highly perishable at the tree-ripe (TR) stage. Commercial-ripe (CR) fruit, which are harvested before the TR stage for their postharvest transportability and shelf-life advantage, are inferior to TR fruit in size, color and sugar content. The succulent urn-shaped receptacle serves as the protective structure and edible part of the fruit, and determines fruit quality. Quantitative iTRAQ reveal the proteins and transcripts that are differentially expressed in fig receptacle at the two harvest stages. We annotated 691 proteins against uni_Moraceae_3487, of which 59 showed ≤1.3 -fold change—in TR vs CR fruit. Ficin was the most abundant soluble protein in the fig receptacle. A high abundance of aminocyclopropane-1-carboxylate oxidase was identified.

Project description:Background: MicroRNAs (miRNAs) represent a family of small endogenous, non-coding RNAs that play critical regulatory roles in plant growth, development, and environmental stress responses. Although Hami melon is an attractive model for valuable biological traits analysis, the role of miRNA action in the fruit development and ripening remains largely unknown. Here, we performed small RNA sequencing to investigate the Hami melon miRNA profiles at four fruit developmental stages Results: Small RNA sequencing yielded raw reads in eight libraries. miRNAs expression profiles were variable at different fruit developmental stages. The expression levels of five known miRNAs were validated by quantitative real-time PCR. Among the identified miRNAs, several miRNAs showed developmentally regulated and differentially expressed pattern during fruit development. Conclusions: Our results present a first comprehensive set of identification and characterization of Hami melon fruit miRNAs and their potential targets, which provide valuable basis for further research on the critical role of miRNAs in melon fruit development.

Project description:We report the construction of an oligo-based microarray using a total of 17,510 unigenes derived from 30,675 high-quality melon ESTs. This chip is particularly enriched with genes that are expressed in fruit and during interaction with pathogens. Hybridizations for three independent experiments allowed the characterization of global gene expression profiles during fruit ripening, as well as in response to viral and fungal infections in plant cotyledons and roots, respectively. Microarray construction, statistical analyses and validation together with functional-enrichment analysis are presented in this study.
