Project description:The transcriptome of Leptosphaeria maculans was analyzed in mycelium and during oilseed rape (Brassica napus) leaf infection. The array probes were designed from gene models from the L. maculans whole genome annotation. One aim of this study was to verify the expression of the automatically annotated gene models in various conditions. Another goal was to monitor gene expression profiles during oilseed rape leaf infection and to highlight tissue-specific transcripts, e.g. in plant up-regulated transcripts, for further analyses. We performed 9 hybridizations (NimbleGen) with samples derived from mycelium and infected oilseed rape leaves. Samples from infected oilseed rape leaves were harvested 7 and 14 days post infection. Three replicates each. All samples were labeled with Cy3.

Project description:High temperature stress results in yield loss and alterations to seed composition during seed filling in oilseed rape (Brassica napus). However, the mechanism underlying this heat response is poorly understood. In this study, we employed a microarray analysis with silique walls and seeds from the developing siliques (20 days after flowering) of Brassica napus that had undergone heat stress. Two-condition experiment, control vs heat stress, 2 time points

Project description:Glutathione (GSH) is a tripeptide involved in controlling heavy metal movement in plants. Our previous study demonstrated that GSH, applied to plant roots site-specifically, inhibited Cd translocation from roots to shoots in oilseed rape plants (Brassica napus) cultured hydroponically. One of the factors of this inhibitory effect was due to activation of Cd efflux from root cells. To investigate the molecular mechanism triggered by root applied GSH in more detail, the Cd movement was monitored non-invasively using a positron-emitting tracer imaging system (PETIS). The Cd absorption and efflux process in roots were visualized successfully. The effects of GSH on Cd efflux from root cells were estimated by analyzing obtained imaging data. Another image analysis suggested that Cd return was activated by GSH, applied to roots, at the shoot base. Cutting the shoot base of oilseed rape plants significantly inhibited Cd efflux from root cells. These experimental results demonstrated the shoot base is playing important roles in distributing Cd in the plant bodies. Furthermore, DNA microarray analysis revealed that over 300 genes in the roots of oilseed rape plants responded to root applied GSH. Among them, transporter proteins, related to heavy metal movement in plants, and proteins related to changing the structure of cell walls were involved.

Project description:To identify oilseed rape genes with a potential role in N-remobilization during leaf senescence of developmentally old leaves in the lower canopy and young leaves in the upper canopy, transcriptomes of leaf number 4 and leaf number 8 of B. napus (cultivar Mozart) were analysed at different harvest time points under mild N deficiency and optimal N fertilization.
