(Submitter supplied) The present work describes the effects on iron homeostasis when copper transport was deregulated in Arabidopsis thaliana by overexpressing copper transporters (COPTOE). A genome-wide analysis conducted on COPT1OE plants, highlighted that iron homeostasis gene expression was affected, both under copper deficiency and excess. Among the inhibited genes were those encoding the iron uptake machinery and their transcriptional regulators. more...

(Submitter supplied) Higher plants have developed sophisticated mechanisms to efficiently acquire and use micronutrients such as copper and iron. In the present work, we studied effects produced by the presence of a wide copper range in growth media and altered copper transport on iron homeostasis in Oryza sativa plants. The global analysis of gene expression in the rice seedlings grown under copper deficiency versus excess in the medium showed an increased expression of the genes involved in iron homeostasis. more...

(Submitter supplied) au13-06_fit - Fe-FIT-Diff - FIT (FER-LIKE IRON DEFICIENCY-INDUCED TRANSCRIPTION FACTOR) is a regulator of Fe deficiency responses in the root. FIT is a basic helix-loop-helix protein. Here, we investigated the transcriptome changes in response to Fe deficiency (- Fe) versus the control condition (+ Fe) in wild type, the fit-3 loss of function mutant and in FIT overexpression plants.
