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.

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:Transcriptome analysis of 7 tissues of commercial tomato (S. lycopersicum cv MoneyMaker) and its wild red-fruited ancestor (S. pimpinellifolium LA0722) genotypes performed to assess expression level of tomato transcriptome and to aid whole genome annotation. Sequencing of fruit at 3 different developmental stages will help to assess gene regulation through ripening.
Project description:Six stages of flower and fruit materials from S. lycopersicum var. Moneymaker (MM), S. lycopersicum var. cerasiforme LA1310 (CC) and Solanum pimpinellifolium PI365967 (PP) including 5DPA, 20DPA, mature green, break stage and red ripen fruits and -2DPA flower
Project description:We sequenced mRNA from immature green (15 days after anthesis) and red (Breaker+10 days) tomato (Solanum lycopersicum) fruit tissues from plants over-expressing SlGLK1 and SlGLK2 and from control plants 'M82' to compare gene expression levels between transgenic fruit and the control. Note: Samples in SRA were assigned the same sample accession. This is incorrect as there are different samples, hence “Source Name” was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.
Project description:Anthocyanins are high value plant antioxidants which are not present in the fruits of cultivated tomato. However, both the dominant gene Anthocyanin fruit (Aft) and the recessive gene atroviolacea (atv), introgressed into domesticated tomato from two different wild Solanum species, stimulate a limited anthocyanin pigmentation. Surprisingly, double mutant Aft/Aft atv/atv tomatoes are characterised by the presence of anthocyanins in the fruit peel, resulting in intensely purple pigmented fruit. We carried out a transcript profiling analysis using GeneChip® Tomato Genome Arrays, in order to identify differentially expressed genes when comparing wild type, Aft/Aft, atv/atv, and Aft/Aft atv/atv fruits. The expression pattern of several genes involved in the anthocyanin pathway was analyzed in detail. Among the fruit peel-associated differentially expressed transcripts, genes involved in phenylpropanoid pathway, cell wall composition, biotic and abiotic stress responses, sugar and hormone metabolism were overrepresented in Aft/Aft atv/atv. Transcriptomic analysis thus revealed that the activation of anthocyanin synthesis in tomato fruit was accompanied by a complex remodulation of gene expression, likely affecting important agronomic and merceological traits. Wild type (Cv. Ailsa Craig, accession number LA2838A), Aft/Aft (accession number LA1996), atv/atv (accession number LA0797) and double mutant (Aft/Aft atv/atv) were grown during the winter season in a controlled heated greenhouse. Fruits were collected at mature green, turning red and red stages of development. The transcriptional profile in Aft/Aft, atv/atv, and Aft/Aft atv/atv fruits when compared to the wild type was analyzed using the GeneChip® Tomato Genome Array.
Project description:Fruit pericarp at two stages, cell expasion and orange red. From Solaunm Lycopersicum and Solaunm Lycopersicum var cerasiforme genotypes. Two Dimensional Polyacrylamide Gel Electrophoresis (Coomasie staining, Band excision, Enzyme digestion) LC/MS (Thermo Finnigan LTQ XL) Software processing (X! Tandem, CYCLONE (2010.12.01.1)) Databases (Contaminants database is a home-made database. It is a set of 25 proteic sequences corresponding to proteins that could be present in the samples, 21 correspond with keratins, 2 with trypsin and 2 with bovin serum albumins. 17 sequences come from SwissProt and 8 from TrEMBL. ITAG2.3 database is the set of proteic sequences predicted in the version 2.3 of the annotation of the tomate genome published by the ITAG group (ftp.solgenomics.net))
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.
