Project description:This study evaluates the transcriptome of transgenic Arabidopsis seedlings expressing the transcription factor TCP14 (AT3G47620) under the UBQ10 promoter.
Project description:This study evaluates the transcriptome of transgenic Arabidopsis seedlings expressing the effector HopBB1 from the bacteria Pseudomonas syringae
Project description:We performed transcriptome and ribosome immunoprecipitation studies of transgenic Arabidopsis (Arabidopsis thaliana) Columbia seeds expressing a His6FLAG-tagged version of the ribosomal large subunit protein L18B (35S:HF-RPL18B)
Project description:DELLA proteins act as hubs that relay environmental information to the multiple transcriptional circuits that control growth and development through physical interaction with transcription factors from different families. We have analyzed the presence of one DELLA protein at the Arabidopsis genome by chromatin immunoprecipitation coupled to large-scale sequencing and we find that it binds at the promoters of multiple genes. Enrichment analysis shows a strong preference for cis elements recognized by specific transcription factor families. In particular, we demonstrate that DELLA proteins are recruited by type-B ARABIDOPSIS RESPONSE REGULATORS (ARR) to the promoters of cytokinin-regulated genes, where they act as transcriptional co-activators. The biological relevance of this mechanism is underpinned by the necessity of simultaneous presence of DELLAs and ARRs to restrict root meristem growth and to promote photomorphogenesis. Provided are 3 biological replicates analysing RGA binding sites in Arabidopsis seedlings. ChIP-seq was performed on plants expressing RGA-GFP under the native RGA promoter and on non-transgenic control plants as reference
