This study evaluates the transcriptome of transgenic Arabidopsis seedlings expressing the transcription factor TCP14 (AT3G47620) under the UBQ10 promoter. Overall design: Arabidopsis thaliana seedlings were grown under short day conditions (9h of light at 21°C - 15h of dark at 18°C) for two weeks. Samples were harvested in the beginning of the light period and used for RNA extraction and Illumina sequencing. Lines Col-0 (4 replicates), UBQ10::YFP-TCP14-3 (4 replicates), UBQ10::YFP-TCP14-4 (1 replicate), and coi1-16 (2 replicates) were used in the experiment. Each replicate corresponds to approximately 30 seedlings grown in the same pot.
