TranscriptomicsTranscription profiling of Arabidopsis dms4-1, drd1-1 and drd1-6 mutant seedlings against wild-type to identify targets of IWR1-like transcription factor
We identified in a forward genetic screen a novel factor required for RNA-directed DNA methylation (IWR1-like transcription factor). The aim of the study was to identify natural targets of this factor and to compare it to targets of drd1 another major key factor required for the RNA silencing proces...

TranscriptomicsEarly effects of cdkf;1 RNAPII CTD Serine-7 kinase mutation on regulation of transcription in 7 days old Arabidopsis seedlings
Serine phosphorylation of conserved Y1S2P3T4S5P6S7 repeats of RNA polymerase II carboxy-terminal domain (RNAPII CTD) plays a central role in the regulation of transcription and co-transcriptional RNA processing. Maintenance of CTD phosphoserine-7 mark in Arabidopsis requires the CDKF;1 kinase, which...

TranscriptomicsNucleosome positioning study of Arabidopsis er/erl1/erl2 mutant using MNase-seq approach
The members of ERECTA family (ERf) leucine-rich receptor like kinases (ERECTA, ERECTA-LIKE1, ERECTA-LIKE2) are involved in various developmental processes and hormonal regulation. In this experiment we showed that inactivation of all three ER's causes wide range of transcriptional changes affecting ...

TranscriptomicsTranscript profiling of Arabidopsis thaliana swi3d mutant with inactivated SWI3D subunit of SWI/SNF complex
SWI3D subunit of SWI/SNF chromatin remodeling complexes (CRCs) is involved in the control of Arabidopsis development. We found, using microarray analysis that inactivation of SWI3D gene caused altered expression of genes belonging to various regulatory pathways, including metabolism, stress, respons...

TranscriptomicsTranscript profiling of Arabidopsis er/erl1/erl2 mutant line
The members of ERECTA family (ERf) leucine-rich receptor like kinases (ERECTA, ERECTA-LIKE1, ERECTA-LIKE2) play important role in various regulatory processes like epidermal patterning, stomata development, meristem size, inflorescence architecture control and hormonal signaling. In this experiment...

TranscriptomicsA plasma membrane calcium ATPase functions in FLS2-mediated immunity
Pattern recognition receptors (PRRs) at the plasma membrane promote plant immunity through the detection of conserved microbe-associated molecular patterns (MAMPs). In plants, the PRR for bacterial flagellin (flg22) is encoded by the receptor kinase FLS2. One of the earliest MAMP responses is the ra...

TranscriptomicsExpression data from Arabidopsis mature siliques
Analysis of the transcriptomes of nearly ripe siliques (18-19 DAP) of the rdo2-1, rdo3 and hub1-2 (rdo4) mutants in comparison with wild-type Ler, using Affymetrix GeneChip Arabidopsis ATH1 Genome Array. The experiment includes rdo2, rdo3, and rdo4 as well the Ler genotypes with three biological rep...

TranscriptomicsStudy of expression changes during RPS4-mediated resistance in Arabidopsis using a temperature-inducible system
Innate immune responses of plant cells confer the first line of defence against pathogens. Signals generated by activated receptors are integrated inside the cell and converge on transcriptional programmes in the nucleus. The Arabidopsis Toll-related intracellular receptor RPS4 operates inside nucle...
