TranscriptomicsSystem responses to equal doses of photosynthetically usable radiation of blue, green, and red light in the marine diatom Phaeodactylum tricornutum.
We have studied the transcriptional, metabolic and photo-physiological responses to light of different spectral quality in the marine diatom Phaeodactylum tricornutum through time-series studies of cultures exposed to equal doses of photosynthetically usable radiation of blue, green and red light. T...

TranscriptomicsTranscriptomic responses in Arabidopsis thaliana to PIPL3 peptide treatment
In order to investigate possible roles of IDL and PIP/PIPL peptides, the transcriptomic response of Arabidopsis seedlings to treatment with PIPL3 peptide was analysed. PIPL3 (At4g37295) was chosen, as no functional data was available for this peptide; furthermore, PIPL3 was expressed in leaf tissue ...

TranscriptomicsAn Integrated Analysis of Molecular Acclimation to High Light in the Marine Diatom Phaeodactylum tricornutum
Photosynthetic diatoms are exposed to rapid and unpredictable changes in irradiance and spectral quality, and must be able to adapt their light harvesting systems to varying light conditions. Molecular mechanisms behind light acclimation in diatoms are largely unknown. We set out to investigate the ...

TranscriptomicsMolecular responses to prolonged darkness and subsequent acclimation to re-illumination in the diatom Phaeodactylum tricornutum
We have investigated both the response to prolonged darkness and the re-acclimation to M-bM-^@M-^\moderate intensityM-bM-^@M-^] white irradiance (E = 100 M-BM-5mol m-2 s-1) in the diatom Phaeodactylum tricornutum, using an integrated approach involving global transcriptional profiling, pigment analy...

TranscriptomicsGene regulation of carbon fixation, storage and utilization in the diatom Phaeodactylum tricornutum acclimated to light/dark cycles
Regulation of carbon metabolism in the diatom Phaeodactylum tricornutum at cell, metabolite and gene expression level in exponential fed-batch cultures is reported. Transcriptional profiles and cell chemistry sampled simultaneously at all time-points provide a comprehensive data set on carbon incorp...

TranscriptomicsSystems Biology approach to identify transcriptome reprogramming in Arabidopsis thaliana during insect and bacterial attack (Brevicoryne brassicae)
We have implemented an integrated Systems Biology approach to analyze overall transcriptomic reprogramming and systems level defense responses in the model plant Arabidopsis thaliana during an insect (Brevicoryne brassicae) and a bacterial (Pseudomonas syringae pv. tomato strain DC3000) attack. The ...

TranscriptomicsGenome-wide profiling of responses to cadmium in the diatom Phaeodactylum tricornutum
The only group of organisms in which a biological function for cadmium has been shown is the diatoms, which are unicellular phytoplankton. Yet diatoms exhibit similar sensitivity to Cd as other groups of phytoplankton. We have investigated responses of Cd on molecular, metabolic and physiological le...

TranscriptomicsThe IDA-LIKE peptides IDL6 and IDL7 are negative modulators of stress responses in Arabidopsis thaliana
We present a functional characterisation of two members of the IDA-LIKE (IDL) peptide family in Arabidopsis thaliana, IDL6 and IDL7. They are processed both C- and N-terminally to produce active peptides. Structure analyses of synthesized IDL6 and IDL7 peptides indicate that they lack secondary stru...

TranscriptomicsTranscriptional profiling of an Fd-GOGAT1/GLU1 mutant in Arabidopsis thaliana
Transcriptional profiling of an Fd-GOGAT1/GLU1 mutant in Arabidopsis thaliana reveals a multiple stress response and extensive reprogramming of the transcriptome Glutamate plays a central position in the synthesis of a variety of organic molecules in plants and is synthesised from nitrate through a ...
