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:Transcriptome analysis of Eggplant cv. PPL during fruit development at 0, 5, 10, 20 and 50 dpa. Eggplant is third most important solanaceae crop species after potato and tomato. It is a versatile crop adapted to different agro-climatic regions and can be grown throughout the year. Unripe eggplant fruit is consumed as cooked vegetable in various ways. It is low in calories and fats, contains mostly water, some protein, fibre and carbohydrates. To decipher molecular mechanisms involved in fruit development eggplant fruit were collected at 0, 5, 10, 20 and 50 dpa and gene expression profiles were analyzed using Affymetrix tomato GeneChip Genome array.
Project description:Pepper fruits at four different developmental stages were collected: early fruit [EF; 1 cm long; 7 days after pollination (dap)], mature green fruit (MG; 6-7 cm length; 20 dap), breaking or turning red fruit (BR; fruit are partially red; 35 dap), and red ripe fruit (RR; fully red; 40 dap). Tomato fruits at corresponding developmental stages were also collected: EF (less than 1cm; 7 dap), MG (40 dap), BR (50 dap), and RR (55 dap). For the monitoring of fruit-specific and fruit ripening-related genes, we did array hybridization by using the leaves as a common reference and each corresponding fruit developmental stage sample.
Project description:Microarray analysis was used to compare the gene expression profiles of red and purple sectors of VIGS (Virus-induced gene silencing)-treated Del/Ros1 fruit in the MoneyMaker background. Fruit were silenced at the mature green stage and harvested at differing number of days after breaker.

To decipher molecular mechanisms involved in fruit development eggplant fruit were collected at 0, 5, 10, 20 and 50 dpa and gene expression profiles were analyzed using Affymetrix tomato GeneChip Genome array. Eggplant plants were was grown under controlled conditions in glasshouse. Flowers were hand-pollinated at anthesis and samples were collected at 0, 5, 10, 20 and 50 days post anthesis (dpa). Total RNA was isolated using SpectrumTM Plant Total RNA kit (Sigma, USA) according to the manufacturerM-bM-^@M-^Ys protocol. Affymetrix tomato GeneChip Genome array (Affymetrix, USA) having 10,000 probe sets was used for transcriptome analysis. Three biological replicates were maintained to test the reproducibility and quality of the chip hybridization. cDNA labeling, array hybridization, staining and washing procedures were carried out as described in the Affymetrix protocols. CEL files having estimated probe intensity values were analyzed with GeneSpring GX-11.5 software (Agilent Technologies, USA) to get differentially expressed transcripts. The Robust Multiarray Average (RMA) algorithm was used for the back ground correction, quantile normalization and median polished probe set summarization to generate single expression value for each probe set. Normalized expression values were log2-transformed and differential expression analysis was performed using unpaired t-test. The p-values were corrected by applying the false discovery rate (FDR) correction (Benjamini and Hochberg, 2000).
Project description:‘Crumbly’ fruit is a developmental disorder in red raspberry (Rubus idaeus) that results in malformed fruit with poor adherence of drupelets to one another. In terms of quality and yield, crumbly fruit has become a serious problem in the raspberry industry resulting in unsaleable fruit and waste. A microarray experiment, using pools of progeny from a segregating mapping population (Glen Moy x Latham) with either 'normal' or 'crumbly' fruit at three different fruit developmental stages ('closed'; 'open'; 'green'), identified several genes that were differentially expressed between the crumbly and non-crumbly phenotypes within three quantitative trait loci (QTL) identified. Analysis of gene function highlighted the importance of processes that compromise ovule fertilization as triggers of the crumbly fruit phenotype.
Project description:Microarray analysis was used to compare the gene expression profiles of red and purple sectors of VIGS (Virus-induced gene silencing)-treated Del/Ros1 fruit in the MoneyMaker background. Fruit were silenced at the mature green stage and harvested at differing number of days after breaker. Custom two-colour microarray (TOM2); where one channel was employed as a common reference.
Project description:Gene expression in wild-type fruit. Strand-specific RNA-Seq data was used to calculate the gene expression value (RPKM) in four wild-type fruit developmental stages including immature fruit at 17DPA, mature green fruit (seeds development completes) at 39DPA, breaker fruit (onset of ripening) at 42DPA and fully ripe fruit at 52DPA. For each sample, two to four biological replicates were sequenced. Note: Samples in SRA were assigned the same sample accession. This is incorrect as there are different samples, hence âSource Nameâ was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.
