Transcription profiling of Arabidopsis root developmental zones after iron deficiency (-Fe) treatment

ABSTRACT: To gain a genome-scale understanding of the role that developmental processes play in regulating stimulus response, we examined the effect of -Fe stress on gene expression along the longitudinal axis of the root. Since roots grow from stem cells located near the tip, the position of cells along the longitudinal axis can be used as a proxy for developmental time, with distance from the root tip correlating with increased differentiation. To estimate the role developmental stage plays in regulating salt response, roots were dissected into four longitudinal zones (LZ data set) after transfer to standard or -Fe media and transcriptionally profiled. Little is known about how developmental cues affect the way cells interpret their environment. Here we characterize the transcriptional response
