Project description:The BnCRY2aOE transgenics over-expressing a blue light photoreceptor (BnCRY2a) flowered earlier than wild-type plants by more than two weeks. To identify the downstream candidate genes involved in regulating the early flowering phenotype in the transgenics, a genome-wide microarray analysis of the transgenic plant vs. wild type was performed. The microarray data analysis revealed the differential up-regulation of many genes involved in flower development, cell growth and differentiation and hormone biosynthesis/signalling in comparison to wild-type.

Project description:To cover a comprehensive understanding of the complex regulatory networks controlling cryptochrome 1(CRY1)-mediated photomorphogenic response in Brassica, a genome-wide differential expression analysis was performed for the 5-day-old T3 BnCRY1-OE and wild type seedlings grown under white light (100 M-BM-5mol mM-bM-^@M-^S2sM-bM-^@M-^S1) on 0.8% agar-gelled MS (Murashige and Skoog) medium containing 2% sucrose. Total RNA was extracted and cleaned up with the Qiagen RNeasy Plant Mini Prep Kit as per the manufacturerM-bM-^@M-^Ys instructions (Qiagen). The yield and RNA purity were determined spectrophotometrically. Integrity of the RNA was checked using Agilent Bioanalyzer (Agilent Technologies, USA). 500 ng RNA of each of the sample was processed for microarray analysis according to Agilent protocol. Keywords: Cryptochrome, Brassica, photomorphogenesis, differential expression.

Project description:In low rainfall regions soils are naturally conditioned with frequent co-occurrence of salinity and alkalinity. Plant salinity responses both at physiological and molecular level have been extensively researched. However, effects of the combined treatment of alkaline salinity that could greatly reduce plant growth and the mechanisms responsible for tolerance remain indeterminate. In Brassica juncea, large reductions in biomass and increased leaf Na+ concentration under alkaline salinity indicates that the combined treatment had greater negative effect than salinity on both growth and the physiological responses of the plant. To determine molecular mechanisms potentially controlling adaptive tolerance responses to salinity and alkaline salinity, the moderately tolerant genotype NDR 8501 was further investigated using microarray analysis. The transcripts of treated leaf tissues verses those of the untreated control sample were analysed after prolonged stress of four weeks. In total, 528 salinity responsive and 1245 alkaline salinity responsive genes were indentified and only 101 genes were expressed jointly in either of the two treatments. Transcription of 37% more genes involved in response to alkaline salinity than salinity alone, which suggests the increased impact and severity of the combined stress on the plant, indicating the transcription of a far greater number of genes likely involved in mitigation and damage control. Transcription of KUP2 and KUP7 genes involved in potassium homeostasis under salinity alone and NHX1 and ENH1 genes for ion (K+ and Na+) homeostasis under alkaline salinity, clearly demonstrated that different genes and genetic pathways are involved in response to each stress. They further provide supporting evidence for the physiological responses that occur in the plant, with massive reprogramming of the transcriptome leading to partial ion exclusion, shuttling and compartmentation. Salinity and alkaline salinity induced gene expression in Brassica juncea leaf was measured at 4 weeks of prolonged treatment of 50 mM NaCl alone and combined with 2.5 mM HCO3- versus non-stressed control. A single experiment was conducted using Brassica juncea genotype NDR 8501 at a single time point (fours weeks after treatment) with three replications per treatment.
