TranscriptomicsTranscriptional response of the marine pennate diatom Phaeodactylum tricornutum to Fe limitation
Diatoms, which are responsible for up to 40% of the 45 to 50 billion metric tons of organic carbon production each year in the sea, are particularly sensitive to Fe stress. Here we describe the transcriptional response of the pennate diatom Phaeodactylum tricornutum to Fe limitation using a partial ...

GenomicsHistone modifications in the marine diatom Phaeodactylum tricornutum
Genome wide mapping of five histone marks (H3K4me2, H3K9me2, H3K9me3, H3K27me3 and H3AcK9/14) as well as nucleosome occupancy was generated by chromatin immunoprecipitation followed by deep sequencing. To gain insights into the dynamic nature of the P. tricornutum epigenome in response to an environ...

TranscriptomicsRNA-seq study of the response of the diatom Leptocylindrus aporus to changing temperature conditions.
The goal of the experiment was to compare the behavior and responses of a warm water diatom species in three different temperatures, low, intermediate and high, with the final aim of investigating possible intraspecific variability and better understanding the physiological plasticity and/or adaptat...

TranscriptomicsTranscription profiling of three atino80 allelic mutants was vs that of wild type and 50B Arabidopsis plants, all Col-0
The transcriptome of the three atino80 allelic mutants was compared to that of wild-type and 50B Arabidopsis plants (see Fritsch et al. 2004). Since the transcriptomes of 50B and wild-type plants were found to be identical, we compared expression in the mutant with 50B and with wild-type without dis...

TranscriptomicsGlobal transcriptome responses of a marine diatom to phosphate fluctuations provides insights into its ecological success
Phosphate (Pi) is an essential element to all living cells yet fluctuations in Pi concentrations are recurrent in the marine environment. Diatoms are amongst the most successful phytoplankton clade living in the world’s oceans adapting to and surviving long periods of sub-optimal conditions and re...

TranscriptomicsWhole genome McrBC-chip on DNA methylation of diatom Phaeodactylum tricornutum
Extensive gene methylation correlated strongly with transcriptional silencing and differential expression under specific conditions. DNA methylation and its role in gene regulation is conserved in stramenopile. Methylome of the whole genome of diatom phaeodactylum tricornutum.
