Transcription profiling of Arabidopsis response to iron (Fe) deficiency - time series

ABSTRACT: We performed a time course analysis (TC data set) of the response of whole seedling roots to -Fe at 6 time points after transfer (3, 6, 12, 24, 48, and 72 hours). Little is known about how developmental cues affect the way cells interpret their environment. Here we characterize the transcriptional response of different cell layers and developmental stages of the Arabidopsis root to high salinity and find that transcriptional responses are highly constrained by developmental parameters. These transcriptional changes lead to the differential regulation of specific biological functions in subsets of cell-layers, several of which correspond to observable physiological changes. We show that known stress pathways primarily control semi-ubiquitous responses and use mutants that disrupt epiderm
