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...

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...

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...

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 ...

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 ...

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...

TranscriptomicsRNA-seq on SIP+-treated mating type minus cultures of Seminavis robusta
In order to obtain a global view on the transcriptional changes induced by the sex-inducing pheromone released by Seminavis robusta mating type plus cells (SIP+), an RNA-seq experiment was conducted. Therefore, purified SIP+ from RP-UPLC/MS was added to MT- cultures, 15 min before light onset after ...

TranscriptomicsINFLORESCENCE DEFICIENT IN ABSCISSION (IDA) and its receptors HAE/HSL2 are required for cell expansion and cell separation during floral organ abscission in Arabidopsis thaliana (part 2)
Plants have the ability to shed organs that are no longer in use. In Arabidopsis thaliana abscission of floral organs involves cell wall remodeling and cell expansion prior to cell wall dissolution. IDA encodes a secreted peptide that signals through the leucine-rich repeat receptor-like kinases (L...

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...
