Microarray expression data for iron and zinc stresses in maize. Microarray expression data for iron and zinc stresses in maize

Elucidation of molecular basis of Iron and zinc homeostasis is crucial to breed iron and zinc use efficient and iron -zinc biofortified maize cultivars. The present investigation was framed to decipher the global expression snapshot maize seedlings in response to iron and zinc starvtion. Genome-wide transcriptome assay was performed with ~18,000 transcripts distributed across the maize genome, in maize seedlings after exposing the seedlings to three Fe and Zn stress treatments (+Fe–Zn, –Fe+Zn, –Fe–Zn) along with control (+Fe+Zn). Microarrays were used to study the global gene expression pattern iron and zinc starvation responsive genes in maize. Overall design: Experiment was designed as a two-factor experiment with the four possible treatments among iron and zinc combination viz., 1) +Fe+Zn, 2) +Fe–Zn, 3) –Fe+Zn and 4) –Fe–Zn. Three biological replications were included in each treatment.
