UVR8-mediated changes in gene expression in response to UV-B, compared to genes misexpressed in pif4pif5 mutants

We analysed global gene expression changes in Arabidopsis thaliana in response to 6h UV-B, applied at the same low level that was seen to promote subsequent UV-B stress tolerance, in order to elucidate the transcriptional reprogramming that leads to UV-B acclimation. mRNA profiles generated by deep sequencing from triplicate replicate Arabidopsis thaliana 4-day-old seedling samples sourced from independent seedling plates either protected from UV-B or exposed to 6h acclimation-level UV-B.
