Project description:In order to find the gene which were regulated by SlLBD40, the fruits of WT and SlLBD40-KO-5 line were collected at 25 DDA to do the RNA-Seq. Total RNA was extracted from above tomato fruits by TRIzol reagent and three biological replicates were taken. The clean data were aligned to the tomato reference genome release SL2.50. According to the RNA-Seq data, many development-related genes were down-regulated in SlLBD40-KO-5 fruit. We find the potential SlLBD40-regulated genes.
Project description:The goal of this research was to measure the gene expression levels thoughout 10 stages of tomato fruit development. Whole buds, flowers or fruits were collected at various developmental timepoints.

Whole buds, flowers or fruits were collected at various developmental timepoints. Total RNA was extracted from 10 stages of flower and fruit development. A single technical and biological repeat was performed. cDNA was amplified and labelled using standard Affymetrix protocols.
Project description:To elucidate the mechanisms of fruit body development in Pleurotus ostreatus, the transcriptomes of four different development stages including mycelium, primordium, young fruit body, and mature fruit body were obtained by RNA-seq.
Project description:Gene expression in three stages of ripening tomato fruit (variety Ailsa Craig) was determined with the EUTOM3 Affymetrix array in order to compare with degradrome sequencing data from study GSE42661, treated as RNAseq.
Project description:To evaluate the role of seeds in fruit quality, we induced parthenocarpy in tomato by regulating ovule-specific auxin synthesis or responsiveness using the INO promoter from A. thaliana, which is expressed in the outer layer of the integuments during early stages of ovule development. We compared these to fruit where the same coding regions were expressed from the DeFH9 promoter which is expressed in carpel tissues during early stages of ovule development. Expression of auxin synthesis or responsiveness genes by both of these promoters produced seedless parthenocarpic tomato fruit. We compared fruit samples using the Affymetrix tomato GeneChip (GPL4741) to determine how gene regulation and expression differed between wild-type and transgenic fruit.

Project description:Gene expression in three stages of ripening tomato fruit (variety Ailsa Craig) was determined with the EUTOM3 Affymetrix array in order to compare with degradrome sequencing data from study GSE42661, treated as RNAseq. three replicates of each stage (MG, mature green; T, turning/breaker; RR, red ripe) were hybridized; Expression values were normalized for each sample and reported by iTAG2.3 cDNA identifier in the accompanying matrix table.

We compared fruit samples using the Affymetrix tomato GeneChip (GPL4741) to determine how gene regulation and expression differed between wild-type and transgenic fruit. Experiment Overall Design: Wild-type fruit with seeds was compared with transgenic lines INO-IaaM, DefH9-IaaM, INO-RolB, and DefH9-RolB. To find genes with seed-specific expression, we also compared the control with wild-type fruit from which seeds had been manually removed. We had three biological replicates for each treatment and control except DefH9-RolB, for which only two replicates were available. Each CEL file from the microarray represents one plant from each line.
Project description:Tomato fruit ripening is associated with a dramatic increase in susceptibility to the fungal pathogen Botrytis cinerea, the causal agent of gray mold. Mature green fruit, prior to ripening, are largely resistant to B. cinerea, whereas red fruit, at the end of ripening, are susceptible to B. cinerea infection. We used microarrays to detail the gene expression changes that are induced by B. cinerea when tomato fruit at unripe and ripe stages are infected. Experiment Overall Design: Tomato fruit at mature green and red ripe stages were wound inoculated with a water suspension of B. cinerea conidia. Twenty four hours post inoculation fruit pericarp and epicarp tissue around and including the inoculation sites was collected and the total RNA extracted. Total RNA was also collected from healthy and mock inoculated fruit.
