Project description:Transcriptome analysis of Allium cepa (Onion) bulb

Project description:Onion is regarded as non-climacteric. In onion, ethylene can suppress sprouting however, the ethylene binding inhibitor, 1-MCP can also suppress sprout growth although it is unknown how ethylene and 1-MCP elicit the same response. In this study, onion bulbs were treated with 10 μL L-1 ethylene or 1 μL L-1 1-MCP individually or in combination for 24 h at 20°C before or after curing (six weeks) at 20 or 28°C then stored at 1°C. Following curing, a subset of these same onion bulbs was stored separately under continuous air or ethylene (10 μL L-1) at 1°C

Following curing, a subset of these same onion bulbs was stored separately under continuous air or ethylene (10 μL L-1) at 1°C Six treatments were chosen for microarray analysis; four samples were taken before curing immediately after treatment with ethylene or 1-MCP or ethylene and 1-MCP in combination for 24 h at 20°C. The other two samples and two were taken at the end of storage following 6 weeks curing at 28°C andafter 29 weeks cold storage (1°C) in continuous air or continuous ethylene totalling 35 weeks storage. The four pre-curing samples used were untreated (control) or treated with EB, MB or EMB and the two samples after storage were control bulbs stored in continuous ethylene or air at 1°C. There were three biological replicates of each of the six treatments making 18 samples in total.

Project description:The goal of this study was to compare differentially expressed transcripts in onion bulbs induced when inoculated with Salmonella using transcriptome profiling (RNA-seq) .Transcriptomic analysis of onion bulb tissue (Variety Don Victor) in response to Salmonella was performed 24 hours and 7 days post-inoculation to identify Differentially Expressed Genes (DEGs) in onion. Within 24 hours of inoculation, 4259 genes were upregulated while 3393 genes were downregulated. After 7 days, 8213 and 6417 genes were up and down-regulated, respectively, as shown below. (FDR<0.05 and Abs (log 2(Y/X) >0)

Project description:This study aimed to compare differentially expressed transcripts in Salmonella recovered from the inoculated onion bulbs using transcriptome profiling (RNA-seq). The Salmonella strains of Salmonella enterica subsp. enterica ser. Newport, isolated from clinical cases affected by the onion-linked outbreak in 2020 (CDC, 2020), was used for the onion bulb inoculation. Transcriptomic analysis of Salmonella was performed 1 day (24 hours) and 7 days post-inoculation to identify Differentially Expressed Genes (DEGs) . 925 and 736 genes were upregulated within 24 hours and seven days after inoculation, while the number of downregulated genes in the same timeframe was 690 and 826, respectively (FDR<0.05 and Abs (log 2(Y/X) >0).
